“This could potentially accelerate vaccine rollout,” they said.
And that in turn could forestall dangerous new mutations.
“Wider coverage without compromising vaccine-induced immunity could help reduce variant emergence,” the paper said.
In recent weeks, several studies on the topic were posted online that were not yet published in scientific journals, showing that one dose of a coronavirus vaccine amplified people’s antibodies from an earlier infection.
People’s immune responses to being infected are highly variable: Most people make considerable and long-lasting antibodies, while others who had milder infections produce relatively few, making it difficult to know how protected they are from the virus.
