Effects of the COVID-19 Pandemic on the Decision and Doubts About Vaccination in Catalonia: Online Cross-sectional Questionnaire
Notice bibliographique
Résumé
BACKGROUND: Hesitancy to get vaccinated during the COVID-19 pandemic may decrease vaccination coverage and facilitate the occurrence of local or global outbreaks. OBJECTIVE: The objective of this study was to analyze the impact of the COVID-19 pandemic in Catalonia on 3 aspects: the decision to get vaccinated against COVID-19, changes in opinion about vaccination in general, and the decision to get vaccinated against other diseases. METHODS: We performed an observational study with the population of Catalonia aged 18 years or over, obtaining information through a self-completed questionnaire in electronic format. Differences between groups were determined using the chi-square test, Mann-Whitney U test, or the Student t test. RESULTS: We analyzed the answers from 1188 respondents, of which 870 were women, 47.0% (558/1187) had sons or daughters under the age of 14 years, and 71.7% (852/1188) had studied at university. Regarding vaccination, 16.3% (193/1187) stated that they had refused a vaccine on some occasion, 76.3% (907/1188) totally agreed with vaccines, 1.9% (23/1188) were indifferent, and 3.5% (41/1188) and 1.2% (14/1188) slightly or totally disagreed with vaccination, respectively. As a result of the pandemic, 90.8% (1069/1177) stated that they would get vaccinated against COVID-19 when they are asked, while 9.2% (108/1177) stated the opposite. A greater intention to get vaccinated was observed among women; people older than 50 years; people without children under 15 years of age; people with beliefs, culture, or family in favor of vaccination; respondents who had not previously rejected other vaccines, were totally in favor of vaccines, or had not increased their doubts about vaccination; and respondents who had not changed their decision about vaccines as a result of the pandemic. Finally, 30.3% (359/1183) reported an increase in their doubts regarding vaccination, and 13.0% (154/1182) stated that they had changed their decision about routinely recommended vaccines as a result of the pandemic. CONCLUSIONS: The population studied was predominantly in favor of vaccination; however, the percentage of people specifically rejecting vaccination against COVID-19 was high. As a result of the pandemic, we detected an increase in doubts about vaccines. Although the final decision about vaccination did not primarily change, some of the respondents did change their opinion about routine vaccinations. This seed of doubt about vaccines may be worrisome as we aim to maintain high vaccination coverage.

Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
