Risks and Trade-offs
- Breakthrough Infections: Vaccinated individuals may still contract COVID-19, especially with immune-evading variants.
- Waning Immunity: Protection decreases over time, making boosters essential.
- Global Inequity: Access to updated vaccines remains uneven, leaving vulnerable populations at risk.
Conclusion
COVID-19 vaccination continues to be one of the most effective public health tools. While not perfect, vaccines drastically reduce severe outcomes and remain safe across populations. The future lies in variant-adapted boosters, global equity, and ongoing research to refine strategies.
