Rubella in Poland in 2021. / Rózyczka w Polsce w 2021 roku.

INTRODUCTION: Rubella is a viral infectious disease, and humans are the only reservoir of the virus. In 2020, all WHO member countries conducted epidemiological surveillance for rubella, and almost all (99%) had access to rubella testing at laboratories operating under the WHO Global Measles and Rubella Laboratory Network. OBJECTIVES: The aim of this study was to evaluate epidemiological indicators of rubella in Poland in 2021 compared to previous years, taking into account the impact of the COVID-19 pandemic. MATERIAL AND METHODS: The assessment of the epidemiological situation was based on a review of data from the bulletin , "Infectious Diseases and Poisons in Poland in 2021" (5), and the assessment of the immunization status of the population was based on data from the bulletin , "Immunization in Poland in 2021" (6). Classification of cases was made based on the definition used in the 2021 surveillance (7). Data from the epidemiological surveillance system "EpiBase" were also used. RESULTS: In 2021, 50 cases of rubella were registered, 48 fewer than in 2020 (98 cases). There was also a decrease in incidence to 0.13 per 100,000, compared to 0.26 per 100,000 in 2020. The highest incidence, regardless of gender and residential environment, was recorded in the 0-4 age group (1.23 per 100 thousand). No cases of congenital rubella syndrome were reported in 2021. CONCLUSIONS: In 2021, there was a decrease in the number of rubella cases in Poland, which could be a result of the COVID-19 pandemic and the introduced restrictions. In addition, rubella was registered 99% on the basis of clinical diagnoses, without the required laboratory confirmation, which means that other rash diseases could be registered as rubella.

Post-campaign coverage evaluation of a measles and rubella supplementary immunization activity in five districts in India, 2019-2020.

BACKGROUND: In alignment with the Measles and Rubella (MR) Strategic Elimination plan, India conducted a mass measles and rubella vaccination campaign across the country between 2017 and 2020 to provide a dose of MR containing vaccine to all children aged 9 months to 15 years. We estimated campaign vaccination coverage in five districts in India and assessed campaign awareness and factors associated with vaccination during the campaign to better understand reasons for not receiving the dose. METHODS AND FINDINGS: Community-based cross-sectional serosurveys were conducted in five districts of India among children aged 9 months to 15 years after the vaccination campaign. Campaign coverage was estimated based on home-based immunization record or caregiver recall. Campaign coverage was stratified by child- and household-level risk factors and descriptive analyses were performed to assess reasons for not receiving the campaign dose. Three thousand three hundred and fifty-seven children aged 9 months to 15 years at the time of the campaign were enrolled. Campaign coverage among children aged 9 months to 5 years documented or by recall ranged from 74.2% in Kanpur Nagar District to 90.4% in Dibrugarh District, Assam. Similar coverage was observed for older children. Caregiver awareness of the campaign varied from 88.3% in Hoshiarpur District, Punjab to 97.6% in Dibrugarh District, Assam, although 8% of children whose caregivers were aware of the campaign were not vaccinated during the campaign. Failure to receive the campaign dose was associated with urban settings, low maternal education, and lack of school attendance although the associations varied by district. CONCLUSION: Awareness of the MR vaccination campaign was high; however, campaign coverage varied by district and did not reach the elimination target of 95% coverage in any of the districts studied. Areas with lower coverage among younger children must be prioritized by strengthening the routine immunization programme and implementing strategies to identify and reach under-vaccinated children.

The path to eradication of rubella.

Since 1969, rubella and its harmful effect on fetuses infected in utero can be prevented by rubella vaccine, usually given in combination with measles vaccine. The rubella vaccine is highly protective both in children and in adults including women intending to become pregnant. Owing to the use of combined measles and rubella vaccines, congenital rubella infection has been eliminated from the Western Hemisphere and nearly all of Europe. Such combined vaccination is now being applied throughout the world, posing the possibility of eventual rubella eradication. The existence of viruses of animals related to rubella does not appear to be a barrier to eradication of the human virus. However, persistent rubella virus in infants infected in utero and of immunosuppressed patients with granulomas may pose a problem for eradication. Nevertheless, this review posits that eradication of rubella is now feasible if routine vaccination of infants and surveillance for chronic infection are correctly applied.

Innovations in vaccine delivery: increasing access, coverage, and equity and lessons learnt from measles and rubella elimination.

Disease eradication and elimination programs drive innovations based on progress toward measurable objectives, evaluations of new strategies and methods, programmatic experiences, and lessons learned from the field. Following progress toward global measles elimination, reducing measles mortality, and increasing introductions of measles and rubella vaccines to national programs, the measles and rubella immunization program has faced setbacks in recent years. Currently available vaccine delivery methods have complicated logistics and drawbacks that create barriers to vaccination; innovations for easier, more efficient, and safer vaccine delivery are needed. Progress can be accelerated by new technologies like microarray patches (MAPs) that are now widely recognized as a potential new tool for enhancing global immunizations efforts. Clinical trials of measles-rubella vaccine MAPs have begun, and several other vaccine MAPs are in the pre-clinical development pathway. MAPs could significantly contribute to Immunization Agenda 2030 priorities, including reaching zero-dose children; increasing vaccine access, demand, coverage, and equity; and achieving measles and rubella elimination. With strong partnerships between public health agencies and biotechnology companies, translational novel vaccine delivery systems can be developed to help solve public health problems and achieve global health priorities.

After the honeymoon, the divorce: Unexpected outcomes of disease control measures against endemic infections.

The lack of effective vaccines for many endemic diseases often forces policymakers to rely on non-immunizing control measures, such as vector control, to reduce the massive burden of these diseases. Controls can have well-known counterintuitive effects on endemic infections, including the honeymoon effect, in which partially effective controls cause not only a greater initial reduction in infection than expected, but also large outbreaks during control resulting from accumulation of susceptibles. Unfortunately, many control measures cannot be maintained indefinitely, and the results of cessation are poorly understood. Here, we examine the results of stopped or failed non-immunizing control measures in endemic settings. By using a mathematical model to compare the cumulative number of cases expected with and without control, we show that deployment of control can lead to a larger total number of infections, counting from the time that control started, than without any control-the divorce effect. This result is directly related to the population-level loss of immunity resulting from non-immunizing controls and is seen in a variety of models when non-immunizing controls are used against an infection that confers immunity. Finally, we examine three control plans for minimizing the magnitude of the divorce effect in seasonal infections and show that they are incapable of eliminating the divorce effect. While we do not suggest stopping control programs that rely on non-immunizing controls, our results strongly argue that the accumulation of susceptibility should be considered before deploying such controls against endemic infections when indefinite use of the control is unlikely. We highlight that our results are particularly germane to endemic mosquito-borne infections, such as dengue virus, both for routine management involving vector control and for field trials of novel control approaches, and in the context of non-pharmaceutical interventions aimed at COVID-19.

Comparing catch-up vaccination programs based on analysis of 2012-13 rubella outbreak in Kawasaki City, Japan.

During the 2012-13 rubella outbreak in Japan, local governments implemented subsidy programs for catch-up vaccination to mitigate the rubella outbreak and prevent congenital rubella syndrome (CRS). In most local governments, to prevent CRS, eligible persons of the subsidy program were women who were planning to have a child and men who were partners of pregnant women. On the other hand, in Kawasaki City, unimmunized men aged 23-39 years were additionally included in the eligible persons, because they were included in an unimmunized men group resulting from the historical transition of the national routine vaccination in Japan. The number of rubella cases in the city decreased earlier than that in the whole Japan. First, in order to estimate the effect of the catch-up vaccination campaign in Kawasaki City on the epidemic outcome, we performed numerical simulations with a Susceptible-Vaccinated-Exposed-Infectious-Recovered (SVEIR) model incorporating real data. The result indicated that the catch-up vaccination campaign showed a beneficial impact on the early decay of the rubella cases. Second, we numerically compared several different implementation strategies of catch-up vaccinations under a fixed amount of total vaccinations. As a result, we found that early and intensive vaccinations are vital for significant reduction in the number of rubella cases and CRS occurrences. Our study suggests that mathematical models with epidemiological and social data can contribute to identifying the most effective vaccination strategy.

Routine Childhood Vaccines Given From 1 through 18 Years of Age.

In addition to the vaccines due in the first year of life, the US Advisory Committee on Immunization Practices recommends that children continue to receive vaccines regularly against a variety of infectious diseases. Starting at 12 to 15 months of life, these include the two-dose measles-mumps-rubella vaccine series and the two-dose varicella vaccine series. Also in the second year of life, infants should begin the two-dose hepatitis A vaccine series and complete the Haemophilus influenzae type B vaccine series as well as the pneumococcal conjugate vaccine series. Before 19 months of life, infants should receive the third dose of the poliovirus vaccine and the fourth dose of diphtheria-tetanus-acellular pertussis (DTaP) vaccine. The final doses of poliovirus and tetanus-diphtheria-acellular pertussis vaccines are both due at 4 to 6 years of life. Before each influenza season, every child should receive the influenza vaccine. Those less than 9 years of age who previously received less than two doses need two doses a month apart. At 11 to 12 years of life, all should get two doses of the human papillomavirus vaccine, the adolescent/adult version of the tetanus-diphtheria-acellular pertussis vaccine, and begin a two-dose series of meningococcal ACWY vaccine. Each of these vaccines is due when the vaccine works to protect against both an immediate risk as well as to provide long-term protection. Each vaccine-preventable disease varies in terms of the nature of exposure, the form of the morbidity, the risk of mortality, and potential to prevent or ameliorate its harm.

A comparative study of the efficacy and safety of intralesional measles, mumps, and rubella vaccine versus intralesional vitamin D3 for the treatment of warts in children.

BACKGROUND: Intralesional vitamin D3 has recently emerged as a new treatment for cutaneous warts. The use of the measles, mumps, and rubella (MMR) vaccine for this purpose is an established modality. However, relevant data on the efficacy of either the MMR vaccine or vitamin D3 as immunotherapy for cutaneous warts in the pediatric population are limited. OBJECTIVES: To compare the efficacy and safety of intralesional injections of MMR vaccine to intralesional injections of vitamin D3 in children aged 8-16 years with multiple warts. METHODS: A total of 74 children were randomly allocated into two groups. Group A patients received intralesional MMR vaccine into the largest wart, and group B received intralesional vitamin D3 into the largest wart. The injections were repeated every 4 weeks until clearance or for a maximum of three treatments. After the last injection, children were followed up every 2 weeks for 3 months, and at the sixth month, a final clinical assessment was conducted. RESULTS: Of 74 children, 60 completed the study, with 30 children in each group. Complete clearance of the injected wart was observed in 26 (86.67%) patients in the MMR group (group A) and 23 (76.7%) patients in the vitamin D3 group (group B). Distant warts cleared in 23 (76.7%) patients in group A compared to 20 (66.6%) patients in group B. There was no significant difference between groups. No recurrence was seen in group A, whereas two (6.6%) children in group B exhibited recurrence in the ensuing 6-month follow-up. The most common adverse events were injection site pain and swelling. CONCLUSION: Both intralesional MMR and vitamin D3 are safe, generally well-tolerated, and equally effective in children for the treatment of cutaneous warts.

Strategies for elimination of rubella in pregnancy and of congenital rubella syndrome in high and upper-middle income countries.

Rubella infection generally leads to mild symptoms; otherwise, in pregnant women it can cause severe damages. The only way to prevent rubella is vaccine. Before the introduction of the vaccine, up to 4 babies in 1000 live births were born with CRS. This work aims to review the most important strategies for the elimination of CRS in upper and high-income countries. Papers were selected through a PubMed search up to January 2019, using keywords rubella, congenital rubella syndrome and epidemiology. Articles published in the last 12 years and referred to upper income and high-income countries in title or abstract were included. Sixty-five papers were selected dealing with one or more of the following strategies: increasing of rubella vaccination coverage in childbearing age women, males, immigrants; exploitation of all appropriate occasions; improving of rubella surveillance. Despite numerous suggestions and indications for valid strategies to eliminate rubella in pregnancy and congenital rubella syndrome, a practical application is often missing.

Rubella IgM epidemiology in the pre-rubella vaccination era in Uganda.

BACKGROUND: Control of Rubella and Congenital Rubella Syndrome using vaccination has shown great success in the America's. Uganda is due to introduce the Rubella vaccine however the magnitude of transmission is not well documented. Therefore this study was done to determine IgM sero-prevalance for Rubella in order to help monitor vaccine effectiveness post introduction of the vaccine in routine vaccination programme. METHODS: A retrospective review of suspected measles cases data for the reporting period January 2007 to December 2016 in Uganda was Done. rubella IgM testing was done on 15,296 of the cases and the data was analyzed using STATA version 13. RESULTS: In total 15,296 cases were tested and 4255 (27.8%) tested positive and among females aged 15-49 years 88 out of 322 (27%) tested positive. The age distribution range was 0-80 years, rubella IgM positivity was reported in all the 15 regions of Uganda and throughout the ten year period in every month. Age group 5-15 years had OR 2.5 p-value < 0.001 of being rubella IgM positive compared to age < 5 years and testing measles IgM negative OR 6.3 p-value < 0.001. CONCLUSION: Rubella is endemic in Uganda and although rubella IgM positivity is highest in the age 5-15 years even the younger, older and women of reprodutive age are affected. This means the risk of Congenital Rubella Syndrome is high hence the need to introduce the rubella vaccine for infants and pregnant mothers and continued surveillance to enhance its control.

Epidemiology of acute rubella infection in Zambia during the pre-vaccination period (2005-2016) as a baseline for monitoring rubella epidemiology in the post-rubella vaccine introduction era.

BACKGROUND: Rubella is highly under reported in Zambia as in most sub-Saharan countries despite being a disease of major public health concern especially among women of childbearing age. In September 2016, Zambia introduced a combined measles-rubella vaccine in children 0-14 years. In this study, we estimated the proportion positive for acute rubella among suspected but negative measles cases between 2005 and 2016 and determined its correlates for monitoring rubella epidemiology post-rubella vaccine introduction. METHODS: In a retrospective study, 4497 measles IgM negative serum samples from 5686 clinically suspected measles cases were examined for rubella IgM antibodies using the Siemens, Enzygnost® ELISA kit at the national measles laboratory. Data on demographics, year and month of onset were extracted from the surveillance data. Multivariate logistic regression analysis using backward variable selection was conducted to determine independent predictors for acute rubella. The magnitude of association was estimated using adjusted odds ratio with a 95% confidence interval. RESULTS: Overall, a proportion of 29.2% (1313/4497) affecting mostly those between 5 and 24 years was determined. Only age, province, month and year were independently associated with acute rubella. The regional proportions varied from 21.8-37.3% peaking in the month of October. Persons in the age group 10-14 years (Adjusted Odds Ratio [AOR] = 2.43; 95% CI [2.01-2.95]) were more likely while those aged < 1 year less likely (AOR = 0.31; 95% CI [021-0.48]) to have acute rubella compared to those aged 25 years or older. Persons in 2010 were less likely (AOR = 0.12; CI [0.05, 0.28]) to have acute rubella compared to those in 2016. While acute rubella was more likely to occur between July and November compared to December, it was less likely to occur between February and May. CONCLUSIONS: Rubella virus was circulating in Zambia between 2005 and 2016 affecting mostly persons in the age group 5-24 years peaking in the hot dry season month of October. Although vaccination against rubella has been launched, these baseline data are important to provide a reference point when determining the impact of the vaccination program implemented.

The cost saving opportunity of introducing a card review into measles-containing vaccination campaigns.

Measles vaccination is a cost-effective way to prevent infection and reduce mortality and morbidity. However, in countries with fragile routine immunization infrastructure, coverage rates are still low and supplementary immunization campaigns (SIAs) are used to reach previously unvaccinated children. During campaigns, vaccine is generally administered to every child, regardless of their vaccination status and as a result, there is the possibility that a child that is already immune to measles (i.e. who has had 2+ vaccinations) would receive an unnecessary dose, resulting in excess cost. Selective vaccination has been proposed as one solution to this; children who were able to provide documentation of previous vaccination would not be vaccinated repeatedly. While this would result in reduced vaccine and supply cost, it would also require additional staff time and increased social mobilization investment, potentially outweighing the benefits. We utilize Monte Carlo simulation to assess under what conditions a selective vaccination policy would indeed result in net savings. We demonstrate that cost savings are possible in contexts with a high joint probability of an individual child having both 2+ previous measles doses and also an available record. We also find that the magnitude of net cost savings is highly dependent on whether a country is using measles-only or measles-rubella vaccine and on the required skill set of the individual who would review the previous vaccination records.

Pesquisa inmuno-epidemiológica en niños con meningoencefalitis vírica vacunados contra la parotiditis, rubeola y sarampión / Immuno-epidemiological inquiry in children suffering viral meningoncephalitis vaccinate against mumps, rubella and measles

En las meningoencefalitis de etiología viral se encuentran implicados los paramixovirus (virus de la parotiditis, sarampión y rubeola). Las vacunas combinadas trivalentes han sido utilizadas durante años en muchos países. El objetivo del trabajo es determinar la respuesta poliespecífica de anticuerpos de tipo IgG anti parotiditis, rubeola y sarampión en pacientes pediátricos con meningoencefalitis víricas agudas. Se realizó un estudio retrospectivo en el año 2018 en muestras de pacientes pediátricos con meningoencefalitis viral aguda vacunados con la triple viral, donde se utilizó el índice de anticuerpos específicos anti-parotiditis, anti-rubeola y anti-sarampión para identificar el estado de respuesta inmunológica contra dichos virus en la muestra estudiada, procedentes de la serorraquioteca de LABCEL. Las determinaciones se hicieron por ELISA. Todos los pacientes presentaron respuesta poliespecífica intratecal, disminución significativa del índice de anticuerpos IgG anti-parotiditis con respecto a la edad y al tiempo de respuesta. Se evidencia un acortamiento del tiempo de respuesta de los anticuerpos de tipo IgG específicos anti-parotiditis en relación a la edad de vacunación(AU)

Paramixovirus like mumps, rubella and measles are involved in some viral meningoencephalitis. Triple combined vaccines have been employed for several years in many countries. The aim of this work is to determine the IgG anti mumps, rubella and measles polyspecific response in pediatric patients with acute viral meningoencephalitis. A 2018 retrospective study in pediatric patients with acute viral meningoencephalitis previously vaccinated with the triple viral vaccine MMR was performed to identify the immune response status against mumps, rubella and measles in samples from LABCEL serum and cerebrospinal fluid collection. Quantification of IgG specific antibody was performed by ELISA. Intrathecal polyspecific response was present in all patients. A significant decrement of anti IgG mumps specific antibody index was observed according to age and response time. A shortage of the response time of IgG mumps specific antibodies according to the age of vaccination was demonstrated(AU)

What are the beliefs and perceptions of practice nurses' influence about the uptake of the measles, mumps, and rubella vaccine?: An integrative literature review.

AIM: The aim of this study was to ascertain the beliefs and perceptions of practice nurses' influence about the uptake of the measles, mumps, and rubella vaccine. BACKGROUND: Immunization decision-making for parents is a complex process. Principle health professionals involved in immunization programmes are health visitors, general practitioners, and practice nurses. There is evidence that health visitors and general practitioners influence parental immunization decision-making. However, there is a lack of evidence about the influence of the practice nurse despite their well-documented role in immunization. DESIGN: Integrative literature review. DATA SOURCES: A systematic search of electronic databases, including CINAHL; Medline; PubMed; Google Scholar; ScienceDirect; and Scopus from February 1998 - April 2017. Hand searching and reviewing of secondary references were also undertaken. REVIEW METHODS: Two reviewers independently screened records on title and abstract. Studies where the beliefs and perceptions of practice nurses about the measles, mumps, and rubella vaccine were explored and were published in English were included. The data were analysed using the integrative review processes. RESULTS: Twelve studies were included; these studies were principally descriptive and were of variable methodological quality. Four themes were identified: parental immunization influencing factors, practice nurse characteristics, information and communication, and personal views and concerns. While this review provides an excellent baseline for this information, more recent research conducted in the current policy environment is urgently needed to determine if these views persist. CONCLUSION: Immunization training and annual updates are essential for practice nurses to keep abreast with the evidence base underpinning national immunization programmes.

Last cases of rubella and congenital rubella syndrome in Spain, 1997-2016: The success of a vaccination program.

With a highly immunized population, rubella infection in Spain is so low that the WHO has declared the elimination of rubella. Rubella in pregnant women is also very rare. The objective of this study is to describe the last cases of congenital rubella syndrome reported and recommend actions to maintain the status of the disease as eliminated. The CRS cases reported to the Spanish National Epidemiological Surveillance Network between 1997 and 2016 were studied, and the epidemiological, clinical, diagnostic and maternal characteristics of newborns with CRS described. The incidence of CRS was calculated using Birth Statistics from the Spanish National Statistics Agency (INE). Twenty-three cases of CRS were reported, 70% of which were associated with rubella outbreaks. The most common clinical conditions were heart disease (52.2%), deafness (39.1%) and cataracts (30.4%); 91.3% of cases were confirmed by laboratory testing. 70.0% were born from a non-vaccinated foreign mother, resident in Spain (cumulative rate incidence (CR): 1.1/100,000 births), with mothers coming from Africa (36.0%), Latin America (29.0%), Eastern Europe (21.0%) and Asia (14.0%). Six were born to Spanish mothers (CR: 0.08/ 100,000 births), the last of which were in 2005. The majority of CRS cases were born to unvaccinated immigrant women infected in Spain during rubella outbreaks. Universal vaccination in childhood is the most efficient strategy to prevent rubella. The limited circulation of the virus will, however, quickly lead to a loss of awareness about rubella among clinicians and epidemiologists. It is necessary to maintain protocols capable of identifying signs consistent with rubella in pregnant women and signs suggestive of congenital rubella in newborns.

Vaccination Status and Other Preventive Measures in Medical Schools. Big Needs and Opportunities.

BACKGROUND: Proper immunization and knowledge in infection prevention are key factors in protecting medical students. AIM OF THE STUDY: To describe the status on vaccination recommended for healthcare workers (HCW) and infection prevention knowledge. METHODS: We conducted a cross-sectional study on medical students at clinical years of medical school from a public University in Mexico. RESULTS: A total of 1,824 medical students responded the survey. One thousand ninety (59.8%) were women. Median age was 22 years. One thousand six hundred twenty-two (88.9%) knew their childhood immunization status. One thousand seventy-one (58.7%) were vaccinated against influenza for the 2016-2017 season; 1667 (91.4%) had been vaccinated at least once against hepatitis B, only 315 (18.9%) of vaccinated had received a full course with 3 doses. Most students were vaccinated against measles, mumps and rubella during childhood, 542 (29.7%) received an additional dosage during or after adolescence. Six hundred ninety-seven (38.2%) were concerned about vaccine's safety. A total of 1,431 (78.5%) properly identified situations were standard precautions are recommended, and 1540 (84.4%) had received some training on safe care delivery and personal protective equipment. Regarding needle-stick injuries, 1165 (63.9%) had been informed on the protocols to follow if an injury occurred. Three hundred forty-nine (19.1%) had suffered needle-stick injuries, only 125 (35.8%) received immediate medical attention at the point of care. CONCLUSIONS: Most medical students were not vaccinated as recommended, and they were not adequately instructed on safe practices for medical attention, nor advised or followed when a health-care related accident occurs. The results may be useful for implementation strategies on vaccination compliance and training on infection prevention.

No. 203-Rubella in Pregnancy.

OBJECTIVE: To provide an update on rubella and pregnancy so that health professionals remain aware of the potentially devastating effects on the developing fetus. OUTCOMES: Rubella vaccination has been effective in virtually eliminating congenital rubella syndrome in Canada. EVIDENCE: Medline, PubMed, and Cochrane Database were searched for articles published between 1985 and 2007. VALUES: The quality of evidence was rated using the criteria described in the report of the Canadian Task Force on Preventive Health Care. SPONSOR: The Society of Obstetricians and Gynaecologists of Canada.

Social capital, trust in health information, and acceptance of Measles-Rubella vaccination campaign in Tamil Nadu: A case-control study.

Background: Parents' decision about vaccination of children is influenced by social relationships and sources of information. The aim of this study was to assess the influence of social capital and trust in health information on the status of Measles-Rubella (MR) vaccination campaign in Tamil Nadu. Materials and Methods: This was a case-control study carried out in Kancheepuram district in Tamil Nadu where the MR vaccination campaign offered by Government of Tamil Nadu had poor acceptance. Cases were parents of children who had refused the MR vaccine and controls were parents having children in the same age group who had accepted the vaccine. Data on social capital and trust in health information were collected by using social capital scale developed by the researchers and trust in the source of information was measured by using simple questions on the level of trust in the information source. Results: Nonadministration of MR vaccine was high among young parents and parents of younger children. Vaccine acceptance was higher when it was offered at school (P < 0.000) and also among parents who trusted school teachers (P < 0.003) and other school children (P < 0.014) as source of information. MR vaccine acceptance was less among parents who trusted social media and WhatsApp information. Greater levels of health-related physical social capital led to greater vaccine hesitancy. Multivariate analysis revealed that greater the age of the child, better parental attitudes toward vaccination, poorer health-related physical social capital, and greater trust in health information provided by school teachers led to overall greater acceptance of the MR vaccine. Conclusion: Strong homogeneous bonding social capital had a negative influence on MR vaccine acceptance. Schools and school teachers played a vital role in influencing parental decision to vaccinate.
