“…This finding is in line with a previous report that 43.86% of students who had not been vaccinated against HPV were unwilling to accept it because of “rumors of serious side effects” 15. In addition, a recent Greek study showed that one of the most common reasons for women refusing vaccination was a fear of adverse effects 16. Moreover, in a cross-sectional study of physicians and medical students in Brazil, only 38.5% believed that HPV vaccination would be free of side effects 17…”

BackgroundThere are still sparse data on vaccination coverage against human papillomavirus (HPV) among students in the health professions. The aim of this study was to investigate HPV vaccination coverage in female students from the health professions in Greece.MethodsA self-administered, anonymous questionnaire was distributed to second-year and third-year female students pursuing degrees in medicine, nursing, and paramedical health disciplines in central Greece.ResultsOverall vaccination coverage was 44.3%. The major reason for lack of vaccination was fear about safety of the vaccine. Participants who had received information about safety of the vaccine from the mass media and paramedical students had lower vaccination coverage in comparison with students who had received information about vaccine safety from alternative sources.ConclusionFurther quantitative and qualitative research is needed to design educational activities targeting female students in the health professions in order to create a positive domino effect and improve HPV vaccination coverage levels in Greece.

“…Knowledge about the HPV vaccine, HPV virus and its relationship with these cancers and anogenital warts is considered fundamental in ensuring informed vaccination decision-making 46, 47, 48. Evidence suggests that improved knowledge may facilitate increased adolescent involvement in immunisation decisions, reduce fear about getting vaccines, increase the likelihood that vaccination decisions are informed and their attitudes to vaccination are favourable 12, 14, 15, 20. It is important to be able to measure these domains in adolescents so that interventions to improve such domains can be evaluated.…”

“…Fear and anxiety regarding the vaccine has also been reported, which may in part be attributed to this lack of knowledge and the presence of myths and rumours 14, 15. This fear and anxiety has been found to not only affect uptake16, 17 but also completion of the vaccine series 18 .…”

ObjectivesWe describe the development and validation of measures of human papillomavirus (HPV)/HPV vaccination knowledge, fear/anxiety about vaccination, involvement in HPV vaccine decision-making, and self-efficacy with regard to getting the vaccine, designed to evaluate the efficacy of an intervention to affect these domains (collectively termed the HAVIQ: HPV Adolescent Vaccine Intervention Questionnaire).Study designLiterature search, cognitive interviews and cross-sectional survey.MethodsA literature search identified existing items that were modified for the present measures. Experts reviewed draft measures for face and content validity. Cognitive interviews with adolescents were also used to assess content validity. Adolescents completed the measures and an internal reliability analysis of each measure was performed.ResultsThe four experts concurred that the measures had face validity. Cognitive interviews identified items requiring refinement. Content validity was examined with ten experts and was deemed acceptable. There were 1800 adolescents who completed the measures; Cronbach's alpha was >0.6 for three of the four measures. The four final measures are brief, comprising 25 items in total.ConclusionsThe measures are robustly developed and validity-tested. The HAVIQ may be used in research settings to evaluate adolescents' knowledge and experiences of the process of HPV vaccination in a school-based vaccination programme.

“…Fear of side effects was an important reason for non-uptake of vaccine in our study and has been cited as a barrier to vaccination in a number of countries [29], [31]–[33]. This can substantially impact programmatic delivery and uptake of vaccine, especially following potentially misleading media coverage [34], [35].…”

Reasons for Receiving or Not Receiving HPV Vaccination in Primary Schoolgirls in Tanzania: A Case Control Study

et al. 2012

BackgroundThere are few data on factors influencing human papillomavirus (HPV) vaccination uptake in sub-Saharan Africa. We examined the characteristics of receivers and non-receivers of HPV vaccination in Tanzania and identified reasons for not receiving the vaccine.MethodsWe conducted a case control study of HPV vaccine receivers and non-receivers within a phase IV cluster-randomised trial of HPV vaccination in 134 primary schools in Tanzania. Girls who failed to receive vaccine (pupil cases) and their parents/guardians (adult cases) and girls who received dose 1 (pupil controls) of the quadrivalent vaccine (Gardasil™) and their parents/guardians (adult controls) were enrolled from 39 schools in a 1∶1 ratio and interviewed about cervical cancer, HPV vaccine knowledge and reasons why they might have received or not received the vaccine. Conditional logistic regression was used to determine factors independently associated with not receiving HPV vaccine.ResultsWe interviewed 159 pupil/adult cases and 245 pupil/adult controls. Adult-factors independently associated with a daughter being a case were older age, owning fewer household items, not attending a school meeting about HPV vaccine, and not knowing anyone with cancer. Pupil-factors for being a case included having a non-positive opinion about the school de-worming programme, poor knowledge about the location of the cervix, and not knowing that a vaccine could prevent cervical cancer. Reasons for actively refusing vaccination included concerns about side effects and infertility. Most adult and pupil cases reported that they would accept the HPV vaccine if it were offered again (97% and 93% respectively).ConclusionsSensitisation messages, especially targeted at older and poorer parents, knowledge retention and parent meetings are critical for vaccine acceptance in Tanzania. Vaccine side effects and fertility concerns should be addressed prior to a national vaccination program. Parents and pupils who initially decline vaccination should be given an opportunity to reconsider their decision.
