COVID-19 vaccines have set off an immune system response that likely offers longer-lasting protection against the coronavirus, according to a new study released on Monday.The findings, which were published in the journal Nature, add more evidence to the notion that people immunized with mRNA vaccines may need less or even no boosters at all after they’ve been given their two shots.
Will you need a yearly COVID-19 booster shot? Some scientists aren’t so sure According to the study, such mRNA-based vaccines create a more “persistent” germinal centre B cell response, essentially meaning that a person’s immune response would be much stronger and more durable.“Germinal centers are the key to a persistent, protective immune response,” said.
