COVID-19 Vaccines Provide Protection Against Newer Variants
COVID-19 cases are rising, but mostly causing mild illness.
New variants are circulating.
Vaccines may not target the new strains perfectly but do offer strong protection against serious illness.
If you've been vaccinated, you still build strong overall protection, even if the virus changes.
Scientists are researching how to improve vaccines for future variants.
COVID-19 cases are surging in parts of Asia and the United States.
Current circulating strains in India include LF.7, XFG, JN.1, and NB.1.8.1.
Vaccines available in India are not specifically designed for current strains.
Prior vaccination offers strong immune protection against severe illness from newer variants.
Vaccinated individuals mount a more robust immune response to evolving variants.
