In short, a recent study of the two mRNA vaccines available in the U.S. tells us, “Yes!”
A retrospective cohort study involving 39,156 asymptomatic adults found that those who had received the two doses of the messenger-RNA-based COVID vaccines from Pfizer/BioNTech or Moderna had an 80% lower likelihood of testing positive for asymptomatic COVID compared with those who had not been vaccinated.
Even just a single dose reduced the risk for asymptomatic infection by 79%.
However, according to study author, Aaron Tande, MD, further studies are required to better understand the impact of vaccination on the virus’ spread.
The study was published in the journal Clinical Infectious Diseases and you can find the full story here.
