COVID-19 impact on childhood vaccination attitudes in pregnant antenatal class attendants in Rome

Abstract Background The COVID-19 pandemic caused a decrease in vaccination rates, impacting vulnerable populations such as pregnant women (PW), who concern about future children’s immunisations. The aim of this study was to assess whether the pandemic led to changes in childhood vaccination attitudes among PW attending antenatal classes at the Fondazione Policlinico Universitario A. Gemelli in Rome. Specifically, it assessed the impact of the pandemic on the perceived usefulness of information sources, their trust in healthcare workers (HCWs) and the National Health Service (NHS), their perception of the risk of infection and severity of vaccine-preventable diseases (VPDs), and their vaccination intentions. Methods A repeated cross-sectional study was conducted across three flu seasons by administering an anonymous questionnaire: one before and two during the pandemic. Intention to vaccinate children was expressed as the percentage of PW who selected each vaccination from the questionnaire. Trust in HCWs and the NHS, and perception of the risk of infection and severity of VPDs were expressed as the percentage of PW who answered “quite” or “very”. For the usefulness of information sources, mean scores were calculated. To assess differences of the three periods a chi-square test was performed (p = 0.05). Results Course attendance surged from 105 to 340. Significant shifts in vaccination intentions were noted: 7.5% and 10% decreases for measles (p = 0.02) and pertussis (p = 0.004), respectively, from 2019-20 to 2020-21. Perceived contagion risk decreased, but perceived disease severity increased. A significant reduction in the proportion of PW suspecting economic interest behind NHS workers promoting vaccination, and an increase in the perceived usefulness of non-institutional websites and of the advice from non-NHS physicians were noted. Conclusions PW’s attitudes towards vaccinations might have been modified by COVID-19 pandemic, regarding risk perception and trust in NHS HCWs. Key messages • Our findings suggests that PW’s attitudes towards childhood vaccinations might be modified by the COVID-19 pandemic, in particular risk perception and trust in NHS healthcare workers. • These findings could help Public Health to develop evidence-based interventions and communication strategies, to maintain vaccine confidence and mitigate potential adverse effects.
