For the week of Jan. 8, as cases of the highly contagious variant surged, the rate of COVID-related deaths among people who had the Johnson & Johnson (J&J) shot was more than five in 100,000, according to figures from the U.S. Centers for Disease Control and Prevention. That compared with about two deaths per 100,000 among those who received the Pfizer or Moderna mRNA vaccines, CBS News reported.

But death rates among those with the J&J shot—which is not an mRNA vaccine—were still much lower than those among unvaccinated Americans. Their death rate was close to 20 per 100,000.

Among people who received booster shots, those initially vaccinated with the J&J vaccine had higher COVID-19 death rates than those who started with doses of Pfizer or Moderna, CBS News reported.
