Abstract
Due to the COVID-19 pandemic, many children missed their routine vaccinations globally. There is insufficient evidence on the trends in vaccination coverage in the private healthcare sector in South Africa. This study explored the changes in childhood vaccination patterns (non-COVID vaccines) in the private healthcare sector in South Africa using medicine claim data. Using the information on medication claims from a South African pharmaceutical benefit management (PBM) company, we performed a quantitative cross-sectional analysis comparing the period before (2018-2019) and during the COVID-19 pandemic (2020-2021). All patients who made claims within the study period were included. This study included 67,830 children aged two years and younger. In particular, from 2018 to 2021, boys (52%) outnumbered girls (48%). Pharmacists consistently held the predominant prescriber role before and during the COVID-19 pandemic. The proportion of children receiving non-COVID-19 vaccines was higher before the pandemic (60%) than during the pandemic (55%). Furthermore, there was a notable decline of 5% in measles vaccination rates during the children's first year of life, while a notable increase was observed for measles (5%), hepatitis A (7.7%), and the pentavalent vaccine (5%) during the second year of life. Governments and private healthcare providers must take action to enhance vaccination coverage rates for children in their first year of life to prevent a resurgence of vaccine-preventable diseases. The results obtained in this study underscore the significance of implementing vaccine catch-up campaigns to address missed vaccination opportunities arising from the impact of the COVID-19 pandemic. Moreover, pharmacists emerged as the predominant healthcare providers responsible for administering vaccinations within the private healthcare sector in South Africa, both prior and during the COVID-19 pandemic. Their pivotal role in the vaccination process warrants due recognition and should not be underestimated.
