Across diverse populations, primary vaccination series consistently demonstrate high effectiveness against COVID-19-related death, often exceeding 90%. However, protection against mortality wanes significantly after six months, though this is effectively restored or enhanced by booster doses, particularly in elderly and high-risk clinical groups.
