(NEXSTAR) – At the start of the vaccination drive in the United States, it was altogether unknown whether the COVID-19 vaccines would prevent transmission of the virus.
But recently, thanks to a series of studies, we’re getting greater clarity about the potential for fully vaccinated people to spread the vaccine.
Dr. Peter Chin-Hong, an infectious disease expert at University of California at San Francisco School of Medicine, said he thinks “it’s very unlikely” that vaccinated people can transmit the virus.
“The more evidence we get, it appears it’s very unlikely for a vaccinated person to transfer the virus to someone else,” he said.
The vaccines are especially effective at preventing asymptomatic disease, which Chin-Hong said is where most of the transmission appears.
Chin-Hong also cited studies out of the United Kingdom and Israel that showed there’s “very little transmission from vaccinated people.”
The study out of Israel, for example, found that the Pfizer vaccine was at least 97% effective in preventing symptomatic disease, critical disease and death.
Similarly, the study found the vaccine to be 94% effective at preventing asymptomatic COVID infections, suggesting the vaccine may help stop transmission of the virus.
The bottom line: If you’re fully vaccinated, the chances of you spreading COVID-19 are very low, which is yet another incentive to get one of the available vaccines.
