Large international studies have confirmed that rare serious side effects can occur, and ongoing research continues to improve our understanding of these events. At the same time, decades of vaccine safety monitoring and extensive real-world evidence indicate that, for most people, COVID-19 vaccines substantially reduced the risk of severe disease, hospitalization, and death during the pandemic.

Staying informed through high-quality scientific research and trusted medical sources remains the best way to make evidence-based decisions.
