92 Trends in COVID-19 Vaccination Coverage among Children <5 Years of Age in Canada
Notice bibliographique
Résumé
Abstract Introduction/Background COVID-19 vaccinations for those aged 6 months to 5 years were announced in the summer of 2022. Specifically, Moderna Spikevax and Pfizer-BioNTech Comirnaty were authorized on July 14, 2022, and September 9, 2022, respectively. Given that this was the last age group to become eligible for vaccination against COVID-19, promoting and measuring vaccination coverage in this vulnerable population is of public health significance. Objectives This analysis describes and compares the trend in vaccination coverage (VC) over the initial weeks of eligibility in those 0-17 years old. Design/Methods Data were obtained from the Canadian COVID-19 Vaccination Coverage Surveillance System and were analyzed to describe and compare VC of those <5, 5-11, and 12-17-year-olds over the first 16 weeks of eligibility. VC is defined as the percent of the population that have received at least 1 dose of a COVID-19 vaccine. Results Sixteen weeks after those <5 years became eligible for vaccination, coverage was 10.9% in those aged 2-4 and 6.3% in those aged <2. Compared to other paediatric age groups, VC in those <5 is markedly lower, where, after 16 weeks of eligibility, coverage in those aged 5–11 was 54.4% and 81.5% in those 12-17. There was an immediate spike in coverage for both 5–11-year-olds and 12–17-year-olds over the first 4 weeks following eligibility, where VC was 40.1% and 63.3%, respectively. A similar increase was not observed 4 weeks following eligibility in those aged <5, where VC was 7.4% in those aged 2-4 and 4.0% in those <2. The weekly increase in VC decreased more rapidly as age groups decreased; weekly increase in VC slowed to less than 1% in 28 weeks, 20 weeks, and 16 weeks after eligibility in those aged 12-17, 5-11, and <5, respectively. Conclusion These data suggest that VC over time in the <5 population has been slow and has not followed the trajectory of other paediatric populations, when compared to the 5-11 and 12-17 age groups. Reasons for this may include but are not limited to parents and guardians’ knowledge, attitudes, and beliefs toward getting their infant children vaccinated, as well as pandemic fatigue, as eligibility for the infant population occurred after the other paediatric age groups.

Prédiction machine sur la base complète
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.
