What impact do FLiRT subvariants have on vaccine efficacy?
Impact of FLiRT Subvariants on Vaccine Efficacy
The FLiRT subvariants of the Omicron variant (B.1.1.529) of SARS-CoV-2 have garnered attention for their potential impact on vaccine efficacy. These subvariants, including KP.2, KP.3, and KP.1.1, exhibit distinct genetic mutations that can affect how the virus interacts with the immune system and responds to vaccination efforts:
Immune Evasion: Certain mutations in FLiRT subvariants may alter viral proteins, such as the spike protein, which is targeted by vaccines to induce immune responses. Variants with mutations in critical regions of the spike protein might evade recognition by antibodies generated from previous infections or vaccinations, potentially reducing vaccine efficacy.
Reduced Neutralization: Studies suggest that FLiRT subvariants, particularly those with specific mutations like E484A and S371L, can lead to reduced neutralization by antibodies. This means that antibodies produced by vaccines or natural infection may be less effective in neutralizing these variants, increasing the risk of breakthrough infections among vaccinated individuals.
Effectiveness of Boosters: Booster doses of vaccines have been recommended to enhance immune responses and extend protection against emerging variants like Omicron and its subvariants. Boosters stimulate a stronger immune response, including broader antibody coverage and T-cell activation, which may help mitigate the impact of mutations seen in FLiRT subvariants.
