RESUMEN
BACKGROUND: Between 2015 and 2018 The Netherlands experienced increases of invasive meningococcal disease (IMD) serogroup W (MenW). Therefore in 2018 the MenACWY vaccination was introduced in the National Immunisation Programme (NIP) and a catch-up campaign was initiated targeting adolescents. This study aimed to gain insight into what factors played a role in the decision-making process regarding the MenACWY vaccination. The focus was on the differences in the decision-making of parents and adolescents in order to assess what factors influence the decisions made. METHODS: An online questionnaire was offered to adolescents and one of their parents. We used random forest analyses to determine which factors best predict the outcome of the MenACWY vaccination decision. We carried out ROC (receiver-operator characteristics) analyses to confirm the predictive value of the variables. RESULTS: Among parents several factors stand out, centring on the process of the decision, their attitude about the MenACWY vaccination, trust in the vaccination, and ideas of important people around them. Among adolescents the three stand-out predictors are the ideas of important people around them, the process of the decision and trust in the vaccination. Parents have prominent influence in the decision-making, while the adolescent's influence in the household decision-making is more limited. Adolescents tend to be less engaged and spend less time thinking about the decision compared to parents. Opinions of parents and adolescents from the same households concerning the factors that are influential do not differ a lot in the final decision-making. CONCLUSIONS: Information about MenACWY vaccination might be mainly addressed to the parents of the adolescents and whereby the dialogue about MenACWY vaccination between parents and adolescents will be stimulated. With regard to the predictor trust in vaccination, raising the frequency of use of certain sources, especially those deemed very reliable among households such as conversations with a GP or the provider of the vaccination (GGD/JGZ), might prove a useful strategy to solidify vaccination uptake numbers.

BACKGROUND: Effective and safe vaccines are available outside national immunization programs (NIP). Increased awareness and vaccine uptake can improve public health. Before the inclusion of maternal pertussis vaccination (MPV) in the Dutch NIP in December 2019, extra communication efforts were undertaken. Here we examine the success of these efforts, investigating women's awareness of and their decision-making process regarding MPV. METHODS: Between December 2018 and January 2019, one year before the introduction of MPV in the NIP, and about three years after MPV was recommended by the Dutch Health Council, pregnant and non-pregnant women (i.e. child younger than two years) were invited to fill out an online questionnaire. Participant's decision-making processes regarding MPV were assessed with an adapted Precaution Adoption Process Model (PAPM), including stages of awareness, engagement, information-seeking, and vaccination behaviour. Furthermore, factors related to the decision-making process were examined. RESULTS: In total, 942 women were included, of whom 62% were non-pregnant. Most of the pregnant and nonpregnant women were aware of MPV during pregnancy (respectively 69 and 56%). Most aware women had heard about MPV through their midwife and the Public Health Institute (PHI) website. Women unaware of MPV reported a need for information, preferably from their midwives. Most aware women felt MPV was important to them (88%) and were classified as "engaged". Of the eligible and "engaged" pregnant women, 58% were vaccinated, versus 38% of "engaged" non-pregnant women. CONCLUSIONS: As the most preferred and trusted source of information, midwives are essential to increasing awareness of MPV. The PHI website is considered to be a reliable information source and is often consulted. To increase awareness, appropriate healthcare workers should be encouraged to actively inform target groups about available, additional vaccinations.

OBJECTIVE: Between 2015 and 2018 The Netherlands experienced increases of invasive meningococcal disease (IMD) serogroup W (MenW), from 0.02 cases/100,000 people between 2010 and 2014 up to 0.5 cases/100,000 in 2017. Therefore in 2018 the MenACWY vaccination was introduced in the National Immunisation Programme (NIP) and a catch-up campaign was initiated among adolescents. This study aimed to gain insight into the decision-making process within households regarding the MenACWY vaccination. The focus was on the differences in the decision-making process of parents and adolescents and of those that had accepted the MenACWY vaccination and those that had not, in order to assess how these types of decisions are made within households. METHOD: We conducted a total of 38 semi-structured interviews in 20 households (7 not vaccinated) with 20 parents and 18 adolescents (18 dyads) across The Netherlands concerning their decision-making process. Interview guides were constructed based on the Precaution Adaption Process (PAP) model. We performed thematic analysis using qualitative data analysis software (MAXQDA). RESULTS: Parents are the main actors in the household decision-making process regarding the MenACWY vaccination. Parents start their decision-making process before adolescents are even aware of the issue. Households in the study took different approaches in involving the adolescent in the decision-making, resulting in three styles of household decision-making: parents decide without the adolescent, parents involve the adolescent, or parents leave it up to the adolescent to decide. CONCLUSION: Parents influence adolescent reasoning, engagement and involvement during the MenACWY vaccination decision-making. And this is the case both among those that have accepted and rejected the MenACWY vaccination. Adolescent engagement with the MenACWY vaccination decision-making is either short-lived or non-existent. However, the moment offers opportunities to engage adolescents on vaccinations and decision-making, with parents as key figures to promote this.
