Daily Mail: Pfizer and Moderna's vaccines are 90% effective at preventing COVID-19 infection after two doses and 80% effective after one shot, real-world study of health care workers finds
* A new CDC real-world study looked at the vaccination status of 4,000 frontline workers between mid-December 2020 and mid-March 2021
* During the study period, 161 unvaccinated people were infected with COVID-19 compared to 8 partially vaccinated people and 3 fully vaccinated people
* Employees who received both doses of Pfizer-BioNTech or Moderna's vaccine lowered their risk of being infected by 90% and one shot reduced the risk by 80%
* It comes as Moderna announced on Monday that it has shipped its 100 millionth dose, out of a 300-million dose order, to the U.S. government
* This week, 10 states plan to open eligibility of vaccines to all adults in line with President Joe Biden's goal of all Americans being eligible by May 1
