Researchers evaluated the electronic health records of 6.4 million vaccine recipients in the US from December 14, 2020 to July 31, 2021, compared to 4.6 million non-vaccinated people with similar demographics and geographic locations. The study looked at only non-Covid related deaths.
The vaccines in use in the US are from Pfizer, Moderna and Johnson & Johnson. The Pfizer and Moderna mRNA vaccines require 2 doses for complete vaccination, while the Johnson & Johnson adenoviral vector vaccine requires only one dose.
* There was a mortality rate of 4.2 deaths per 1,000 vaccinated people per year after the first dose and a mortality rate of 3.5 after the second dose in those receiving the Pfizer vaccine, compared with 11.1 in the non-vaccinated comparison group (see table ).
* Moderna vaccine recipients had 3.7 deaths per 1,000 people per year after the first dose and 3.4 after the second; The death rate was 11.1 per 1,000 people per year in the non-vaccinated comparison group.
* There were 8.4 deaths per 1,000 people per year in J&J recipients, compared with 14.7 in the non-vaccinated group.
