Abstract
Introduction. Vaccination remains the most effective measure to combat infectious diseases. The COVID-19 pandemic has made adjustments to the work of pediatric health services around the world, which has affected all aspects of life, including routine immunization of children.
Objective. To analyze the indicators of coverage and timeliness of vaccination of children of the first year of life in the pre-pandemic period and during the COVID-19 pandemic, to assess the frequency and severity of post-vaccination reactions in children of the first year of life.
Materials and methods. A retrospective single-center study of medical documentation (form 112/y) of 414 children was conducted on the basis of GBU RO “City Children’s Polyclinic No. 3” in Ryazan, who were divided into 2 groups: group 1 — children born in 2018 (n = 256), among whom 47.5% (n = 122) were girls, 51.5% (n = 134) are boys, group 2 are children born in 2020 (n = 158), of which 49% (n = 77) are girls, 51% (n = 81) are boys. The assessment of intergroup differences was carried out using the Pearson criterion (χ2), adjusted for small samples. The difference in values was considered statistically significant at p < 0.05.
Results. Vaccination coverage in 2018 and 2020 was 95% and 98%, respectively (p < 0.05). The post-vaccination period in the majority of vaccinated children in group 1 (85%, n = 208) and in group 2 (81%, n = 128) proceeded smoothly (p = 0.04).
Conclusion. The COVID-19 pandemic did not have a negative impact on routine vaccination in the population of children in the first year of life.
