"At this time, we really don’t have sufficient data to quantify what that risk is, but as this resurgence continues to grow with the delta variant. "We think it's quite rare that a vaccinated individual is infecting another vaccinated individual," he said.
Shaun Truelove, assistant scientist at the Johns Hopkins Bloomberg School of Public Health. It's even more uncommon for a vaccinated person to transmit the virus to another vaccinated person, though "not impossible," said Dr. If they get in contact with people who are infected, they might get infected, but the majority may not transmit,” he said. “Individuals who are vaccinated have a good immune response. In that event, health experts said, a fully vaccinated person who gets COVID-19 won’t be contagious for very long and may not have the chance to transmit the virus to another person.Ī vaccinated person may have the same viral loads as an unvaccinated person, but that high level of virus lasts only three to four days compared with an unvaccinated person who could be contagious for up to 10 days, said Suresh Mittal, professor of virology at Purdue University’s College of Veterinary Medicine. As masking recommendations for the vaccinated change, one aspect of the transmissibility debate can be overlooked.Ĭases of breakthrough infections among the vaccinated remain rare.
As the country confronts a massive surge of coronavirus cases, fully vaccinated Americans worry whether they're adequately protected.
