Researchers examined data from employee health records of more than 36,600 health care workers in California and found that ?less than 1% tested positive for COVID-19 after being fully vaccinated -- meaning both doses plus two weeks for the immunity to build -- with the Pfizer or Moderna vaccines.
Not a single vaccinated health care worker who contracted COVID-19 was hospitalized or died and those who did get sick appeared to have milder symptoms than the unvaccinated, according to the researchers.
