Who benefited the most?
Vaccines provided the most significant protection for the elderly and those with underlying health conditions, who were at the highest risk for severe outcomes from COVID-19.
- Older adults: A 2025 study found that people aged 60 and older accounted for nearly 90% of the estimated lives saved between 2020 and 2024.
- High-risk populations: Research on high-risk individuals, such as heart failure patients, showed that vaccinated individuals had significantly lower rates of hospitalization, ICU admission, and death compared to their unvaccinated counterparts.
