Research correspondence e-published on September 8 in the New England Journal of Medicine, looking at rates of COVID infections in 194,362 household members of 144,525 health care workers, pre and post vaccination of the workers:
“We provide empirical evidence suggesting that vaccination may reduce transmission by showing that vaccination of health care workers is associated with a decrease in documented cases of Covid-19 among members of their households”
“Relative to the period before each health care worker was vaccinated, the hazard ratio for a household member to become infected was 0.70 (95% confidence interval [CI], 0.63 to 0.78) for the period beginning 14 days after the first dose and 0.46 (95% CI, 0.30 to 0.70) for the period beginning 14 days after the second dose”

Vaccination – it’s NOT just to protect you, but to protect others – including your family.
