COVID‐19 Vaccine Effectiveness Against Hospitalizations and Severe Outcomes in Kosovo, 2022–2024: A Test‐Negative Case–Control Study
Our findings suggest that COVID-19 vaccination in Kosovo offered substantial protection against hospitalization and severe outcomes within 6 months, though confidence intervals were wide for some subgroups. Effectiveness waned after 6 months, highlighting the need for periodic booster doses.
