The Impact of COVID-19 Pandemic Lockdown on Routine Immunization in the Province of Laghman, Afghanistan

Abstract

Background: The COVID-19 pandemic, declared by the World Health Organization as a public health international emergency concern in March 2020, has caused serious impacts on individuals, families, communities, and societies across the globe. The COVID-19 pandemic not only disrupted the health systems and the economy, but also significantly impacted routine immunization programs. Aim: To study the impact of the COVID-19 pandemic lockdown on the routine immunization coverage program in the province of Laghman, Afghanistan. Methods: A comparative cross-sectional quantitative study was conducted to understand the impact of COVID-19 on routine childhood immunization during the study period. Secondary data was used from the Ministry of Health from April to July 2020 and compared with the historical data of the same period in 2019. Student t-test was used to test the association between the mean changes in the daily immunization coverage. A p-value< 0.05 was considered as statistically significant with 95% confidence interval. Results: There was a 21.4% significant (p< 0.01) decline in the total immunization coverage during April–July 2020 compared to April–July 2019. This reduction was diverse across all districts and all vaccine antigens. The most affected district was Alingar, and the most affected vaccines were measles and OPV4, with 28% declines, followed by PCV3 at 26%, and DPT3, IPV, OPV3, PCV2 and rotavirus at 23%. The outreach vaccination coverage declined by 56.1% compared to the fixed, at 13.4%. Conclusion: The COVID-19 pandemic seriously affected the routine immunization in Afghanistan. On average, 325 children per day missed out on a lifesaving vaccine in Laghman province which put them at risk of getting preventable diseases. To provide access to routine immunization during pandemics, the study suggests a set of customized interventions to strengthen and sustain routine immunization.
