Excerpt:
Compared with the unvaccinated, fully vaccinated people overall had a much lower chance of testing positive for the virus or dying from it, even through the summer’s Delta surge and the relaxation of pandemic restrictions in many parts of the country. But the data indicates that immunity against infection may be slowly waning for vaccinated people, even as the vaccines continue to be strongly protective against severe illness and death.
“The No. 1 take-home message is that these vaccines are still working,” said Dr. David Dowdy, an epidemiologist at the Johns Hopkins Bloomberg School of Public Health. “If you saw these data for any disease other than Covid, what everyone’s eyes would be drawn to is the difference between the unvaccinated and fully vaccinated lines.”
The data shows notable differences in breakthrough death rates by age and slight differences in both case and death rates by vaccine brand, trends that experts say are important to consider as tens of millions of Americans weigh whether to get a booster shot.
