Risks and Trade-offs

  • Breakthrough Infections: Vaccinated individuals may still contract COVID-19, especially with immune-evading variants.

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.
