✔ Describe the size of annual epidemic waves and how seasonal respiratory (breathing related) viruses, like influenza and RSV, attack particular age groups.
✔ Describe how many people have antibodies to key pathogens included in the expanded programme on immunization. This will help identify the immunity gaps which will guide vaccine introductions and schedules.
✔ Establishing a platform for repeated population-based serosurveillance for diseases of public health importance in South Africa = basically creating
✔ To assess the different anti-spike binding antibody patterns which will help to inform our understanding of which variants of COVID-19 dominantly circulating and differentiate between recent and historic infections
✔ To establish influenza and RSV microneutralization assays (tests how antibodies are inhibiting a virus) to assess the impact of seasonal viral evolution on the antibody response to these respiratory (breathing related) viruses (e.g. COVID-19, the flu, etc).
