“A November 2022
studyexamined the spread of the omicron variant in California state prisons and found that participants who received at least one dose of the vaccine were 24% less likely to infect close contacts than those who were unvaccinated, those who had been previously infected were 21% less likely to spread the virus and participants who were previously infected and vaccinated were 41% less likely to pass on the virus.”
“mRNA Covid vaccines in pregnant people are linked to lower hospitalization rates in infants six months and younger, who are not eligible for any Covid vaccines. Infant vaccine effectiveness from two maternal doses against delta was 95%, and 97% against hospitalization due to the delta variant. Infant vaccine effectiveness from two maternal doses against omicron infection was 53%, and 73% against hospitalization due to omicron.”
Studies estimate Covid vaccines prevented millions of deaths and even more hospitalizations.
