About the Nested Serosurvey in Zambia

Since the impact of SIAs on population immunity cannot be adequately determined by vaccination coverage estimates alone, we used a serological survey to estimate the proportion of susceptible children vaccinated during an SIA. This was done by testing for measles and rubella IgG antibodies immediately following measles and rubella vaccination, well before the vaccine response can be detected, during the measles and rubella SIA conducted in Zambia in November 2020. To provide additional data to assess the acceptability and feasibility of collecting specimens during the vaccination campaign, we also collected qualitative data from the vaccination teams at the campaign sites. This analysis will focus on evaluating the integration of specimen collection into the vaccination campaign.
