represent a risk to ongoing vaccination campaigns against Sars-CoV-2 and to world health, according to a report released on Thursday in PLOS Pathogens.

Researchers advocate for sarbecovirus immunizations against all strains, not just Sars-CoV-2.

Khosta-1 and Khosta-2 were discovered in Russian bats in 2020, but experts did not believe they posed a threat to people.
