[Effects of Covid-19 Pandemic on the Vaccine Activities on a Reference Immunization Center in Treichville, Côte D'ivoire].

Since March 11, 2020, Côte d'Ivoire has been affected by the coronavirus epidemic, declared that same day as pandemic by WHO. March 11, 2021, one year after the pandemic, Côte d'Ivoire has notified 36,824 cases of Covid-19 patients and among them 211 have died. As of May 31, 2020, Côte d'Ivoire had already notified 2,833 cases and 33 deaths. At that time, false rumors were circulating in Africa about the setting up of clinical trials on candidate vaccines. The impact of these rumors on the overall use of health services had to be measured and in particular on vaccination centers. The objective of this study was to determine the effects of the pandemic on the activities of the immunization services of the National Institute of Public Hygiene in Abidjan, which comprises four departments: International Vaccination Center, Community Vaccination Service, Rabies Center, and Vaccination Unit of the Expanded Program on Immunization. The study was based on activity reports of the immunization services. At the International Vaccination Center, activities fell by about 50% in March, 86% in April and 82% in May in comparison with 2018 and 2019. Activities of Community Vaccination Service decreased by about 26% in March and 99% in April and May. At the Rabies Control Center, this reduction was estimated at 38% in April and 45% in May. The highest losses were for yellow fever and meningitis vaccines. The drop in attendance at vaccination services could increase the risk of epidemics, especially yellow fever, which are recurrent in Abidjan. Intensive awareness and catch-up actions should be carried out and further studies performed to assess the impact of the pandemic on immunization activities.
