(NEXSTAR) – At the start of the vaccination drive in the United States, it was not clear whether the COVID-19 vaccine would prevent the spread of the virus.
But recently, through a series of studies, including real-world data, we have gained greater clarity on the potential of fully vaccinated people to spread vaccines.
Dr. Peter Shinhong, an infectious disease specialist at the University of California at San Francisco School of Medicine, said he thought it was “very unlikely” that vaccinated people could transmit the virus.
“The more evidence we get, the more immunized people seem to be able to pass the virus to others,”; he said.
The vaccine is particularly effective against asymptomatic disease, Chin-Hong said, where most transmission occurs.
Chin-Hong also cited real-world studies from the UK and Israel that showed “The transmission of infection from people who has received the vaccine is very low.”
For example, an Israeli study found that Pfizer vaccine was at least 97 percent effective in preventing severe disease and death.
Likewise, studies have found the vaccine is 94 percent effective at preventing asymptomatic COVID infection, suggesting that the vaccine may help stop the spread of the virus.
Bottom Line: If you’ve been fully vaccinated, your chances of spreading COVID-19 are very low, which is another available vaccine incentive.
