UK Boosters Neutralize Bat Viruses, Shaping Future Vaccines

Summary

Story summary

Cambridge researchers found that COVID-19 boosters in UK adults generated antibodies that neutralized two bat and pangolin sarbecoviruses better than the Wuhan strain.
A 2023 Nigerian study showed most unvaccinated adults had multiple SARS-CoV-2 exposures, with first-encounter antibodies limiting responses to later variants.
Researchers said the findings could guide next-generation vaccines that target conserved spike regions and account for diverse immune histories.
