Background: The COVID-19 pandemic has caused a disruption in childhood immunization coverage around the world. This study aimed to determine the change in immunization coverage for children under 2 years old in Ontario, Canada, comparing time periods pre-pandemic to during the pandemic. Methods: We conducted an observational retrospective open cohort study, using primary care electronic medical record data from the University of Toronto Practice-Based Research Network (UTOPIAN) database, from January 2019 to December 2020. Children under 2 years old who had at least 2 visits recorded in UTOPIAN were included. We measured up-to-date (UTD) immunization coverage rates, overall and by type of vaccine (DTaP-IPV-Hib, Pneu-C-13, Rot, Men-C-C, MMR, Var), and on-time immunization coverage rates by age milestone (2, 4, 6, 12, 15 and 18 months). We compared average coverage rates over 3 periods of time: January 2019-March 2020 (T1); March-July 2020 (T2); and August-December 2020 (T3). Results: 12,313 children were included. Overall UTD coverage for all children was 71.0% in T1, dropped by 5.7% (95% CI: -6.2, -5.1) in T2, slightly increased in T3 but remained lower than in T1. MMR vaccine UTD coverage slightly decreased in T2 and T3 by approximately 2%. The largest decreases were seen at ages 15-month and 18-month old, with drops in on-time coverage of 14.7% (95% CI: -18.7, -10.6) and 16.4% (95% CI: -20.0, -12.8) respectively during T2. When stratified by sociodemographic characteristics, no specific subgroup of children was found to have been differentially impacted by the pandemic. Conclusion: Childhood immunization coverage rates for children under 2 years in Ontario decreased significantly during the early period of the COVID-19 pandemic and only partially recovered during the rest of 2020. Public health and educational interventions for providers and parents are needed to ensure adequate catch-up of delayed/missed immunizations to prevent potential outbreaks of vaccine-preventable diseases.

Attitude And Practice

Background: Many parents have poor understanding of vaccine preventable diseases (VPD) and many believe in false propagations about the contents, side effects and effectiveness of vaccines. Lack of good knowledge and positive attitude about childhood immunization was believed to be the root cause for resurgence of VPDs. Aim of the study was to assess the knowledge, attitude and practice regarding childhood immunization among mothers of under five children.Methods: A cross sectional study was done among mothers with at least one child in the under-five age group residing in the rural field practice area of a teaching institution. Assuming 61% mothers have good knowledge (Mangalore study) the sample size was calculated to be 235 with 20% error and 1.5 design effect. Data was collected with the help of pretested semi structured questionnaire by interviewing 15 eligible mothers from each of 16 wards. Descriptive analysis was done.Results: The average age of the participants was 27.30±5.42 years with many of them educated up to 10th grade (40.3%) and most being housewife (74.5%). Knowledge of mothers regarding the diseases that can be prevented by immunization was fairly good. But the knowledge regarding individual vaccines, their dosages and schedule were found to be low. Majority of mothers had good attitude about immunization. Immunization coverage of the locality was relatively good (87.7%). Significant relation was established between attitude and practice. Sick at the time of vaccination was the most common cause of being partially immunised (68.96%).Conclusions: Intensify the awareness classes for mothers and religious leaders on immunisation.

The Impact

Maintaining high vaccine coverage (VC) for pediatric vaccinations is crucial to ensure herd immunity, reducing the risk of vaccine-preventable diseases (VPD). The Italian vaccination Law (n. 119/2017) reinforced mandates for polio, diphtheria, tetanus, and hepatitis B, extending the mandate to pertussis, Haemophilus influenzae type b, chickenpox, measles, mumps, and rubella, for children up to 16 years of age. We analyzed the national temporal trends of childhood immunization rates from 2014 to 2019 to evaluate the impact of the mandatory reinforcement law set in 2017 as a sustainable public health strategy in Italy. In a 3-year period, 9 of the 10 compulsory vaccinations reached the threshold of 95% and VC for chicken pox increased up to 90.5%, significantly. During the same period, the recommended vaccinations (against meningococcus B and C, pneumococcus, and rotavirus) also recorded a significant increase in VC trends. In conclusion, although the reinforcement of compulsory vaccination generated a wide public debate that was amplified by traditional and social media, the 3-year evaluation highlights positive results.

Full Immunization

Background: Childhood immunization contributes significantly in the reduction of cases of vaccine preventable diseases in children. DHIS2 data showed that only 60.59% of children under one were fully immunized in 2020. This implies that 39.41% did not receive all recommended vaccinations therefore at risk of contracting vaccine preventable diseases. This study therefore examined the effect of full immunization coverage on incidence of vaccine preventable diseases.Methods: Full childhood immunization coverage and incidence of vaccine preventable disease was examined using simple linear regression model at 5% level of significance and 95% confidence interval. Measles new case for children under five was the dependent variable while children under one fully immunized was the independent variable. Data was retrieved from DHIS2 for the period 2017-2020.Results: The study showed a negative relationship between full immunization coverage and incidence of under-five measles new cases. The study found that any unit increase in full immunization coverage would lead to decrease in measles cases by 6%.Conclusions: Full immunization coverage is still low (below WHO target of 80%) despite effort by government and partners. This implies that a lot of children are at risk of contracting vaccine preventable diseases. In order to avert this risk, health authorities and partners should devise appropriate means of educating the populace on the importance of childhood immunization.
