Effectiveness of Existing Vaccines: Existing COVID-19 vaccines may offer some protection against JN.1, though effectiveness is reduced
Recent studies have indicated that existing COVID-19 vaccines may provide some level of protection against the JN.1 variant, although their effectiveness is notably reduced compared to earlier strains of the virus. This reduction in efficacy is primarily due to the significant mutations present in the JN.1 variant, which allow it to evade some of the immune responses generated by the current vaccines.
