Conclusion

The COVID-19 pandemic has been one of the most significant global health crises in modern history, with devastating effects on public health, economies, and social structures. While vaccination efforts have reduced severe outcomes, new variants and uneven global vaccine distribution remain challenges. Continued monitoring, data transparency, and international cooperation are essential to managing future waves and preventing similar crises.
