Vaccine-hesitant families are more susceptible to verbal communication messaging.

OBJECTIVES: Our survey aims to highlight parents' and healthcare workers' opinions and hesitations regarding children's vaccination, identify the main factors influencing these opinions, and assess the impact of hesitations on immunisation for children, included in the National Immunisation Programme in Lithuania. METHODS: We used the questionnaire developed by the European Academy of Paediatrics Research in Ambulatory Settings Network (EAPRASnet). This questionnaire is designed to assess attitudes toward vaccination. The study involved parents raising children aged 1-4 years and primary healthcare providers (paediatricians, family doctors and nurses). RESULTS: We analysed the completed questionnaires from a total of 329 parents (142 fathers, 187 mothers) and 386 medical personnel (150 physicians, 236 nurses). Most parents expressed positive opinions about vaccines (> 8 points out of 10 possible), with older parents exhibiting more favourable attitudes. Compared to mothers, fathers showed more criticism regarding the information provided by physicians (p = 0.04). Family doctors and paediatricians were more supportive of vaccination than nurses and homoeopaths (p < 0.001). Parents and healthcare providers with higher education showed statistically significantly stronger opinions about the benefits of vaccines than those with lower education levels (p = 0.01 for parents, p < 0.001 for physicians and nurses). The Internet was identified as the primary source of negative information for both parents (69.6%) and healthcare providers (86%). However, verbal information received from medical staff during patient consultations or informal conversations among colleagues had the greatest impact on parents' opinions (17.3%) and medical personnel (35.5%). CONCLUSIONS: Confidential conversations with physicians and nurses remain the most trustworthy sources of information and influential factors shaping opinions. The Internet serves as the primary source of inaccurate information about vaccinations for both parents and medical professionals, although verbal information from primary healthcare providers has a more significant impact on vaccination attitudes. Discrepancies in basic education and specific knowledge about vaccination within the same family can pose additional obstacles to child vaccination.

BCG masking phenomena might depend on the species of Mycobacterium.

This study investigated BCG masking dependency on the species of Mycobacterium through the immune response to the mycobacterial region of deletion 1 (RD-1) associated growth affecting proteins (GEP).To evaluate the effects of GEP, 8-week old female BALB/c mice were immunized with either the wild type Mycobacterium bovis (MBGEP) or the ATCC Mycobacterium avium subsp. avium (MAGEP) strain and then subjected to further exposure with Mycobacterium terrae or M. avium sub. avium. Mice immunized with MAGEP and those mice further exposed to M. avium subsp. avium had increased granulocytes (GRA) and monocytes to lymphocytes rate (MLR) compared to control mice. Immunization of mice with GEP induced an antibody response one month after primary immunization, as observed by cross-reactivity. Our findings suggest that MAGEP is related to a latent hypersensitivity reaction and an increased risk of mycobacterial infection susceptibility. According to the results of the present study, previous sensitization with NTM antigens results in varying immune reactions after contact with different NTM argued that masking phenomena may be dependent on the species of Mycobacterium.
