A comprehensive review in The Lancet confirms that mRNA vaccines remain safe and highly effective against COVID-19. The study notes that while effectiveness wanes over time, booster doses provide significant protection against severe outcomes.
Why it matters
This data provides clinical validation for public health policies and helps address ongoing public concerns regarding vaccine safety.
A new review published in The Lancet has reaffirmed that currently approved messenger RNA (mRNA) vaccines remain safe and highly effective, drawing on data from billions of administered doses across diverse populations, including children, pregnant individuals, and immunocompromised patients. The analysis—which was led by investigators from the University of British Columbia and Imperial College London—pooled laboratory research, clinical trial results, and real-world surveillance data to evaluate the safety profile and the public health impact of mRNA vaccination since its emergency rollout during the COVID-19 pandemic.1,2
