A comment on Omicron variant more resistant to vaccine but causes less severe Covid: study. Parent comment
Efficacy dropped to 60% vs Delta, and drops again to 30% vs Omicron. Boosters seem to rise back up to 90% vs Delta and 75% vs Omicron.
That's why so many people are talking about boosters: it has a measurable impact on transmission for Omicron (and Delta).
