Latest research findings show that vaccine-elicited neutralizing antibodies against SARS-CoV-2 are mostly directed against one of the two main domains of the viral entry machinery.
The findings also point out a key role of the same domain of the spike in eliciting a broad antibody response against many variants, as well as related viruses.
Both findings suggest strategies for clinical development of variant-resistant vaccines and sarbecovirus vaccines as part of future pandemic preparedness.
Spike proteins, which give the virus its crown-like appearance, provide the means for the virus to enter host cells. One subunit of the spike protein engages with a receptor on the host cell and recognizes when a proper landing has occurred.
