Surprising spread among vaccinated people Of 8.9 million young people who got a shot, only 863 serious events were reported as possible side effects, a miniscule fraction of the vaccinations. “There is a significant difference between having a fever and dying from COVID-19.”Īnother CDC report released Friday shows that the COVID-19 vaccines are typically safe for preteens and teens. The vaccines are still extremely effective against delta,” said Rachael Piltch-Loeb, a public health emergency preparedness and response fellow at Harvard T.H. “The biggest takeaway is that we need more people to be vaccinated. The masking recommendation was updated to ensure the vaccinated public would not unknowingly transmit virus to others, including their unvaccinated or immunocompromised loved ones.”Įxperts say the report shows the importance of getting a shot to prevent hospitalizations and deaths as the virus continues to circulate. “This finding is concerning and was a pivotal discovery leading to CDC’s updated mask recommendation. “High viral loads suggest an increased risk of transmission and raised concern that, unlike with other variants, vaccinated people infected with Delta can transmit the virus,” CDC Director Rochelle Walensky said in a statement.

The viral load of vaccinated people with breakthrough cases is the same as in unvaccinated people, the CDC said Friday. The newly released report showing that vaccinated people can still be superspreaders drove the recent decision by the CDC to once again recommend masks for vaccinated people indoors where case counts are high or substantial.

New Centers for Disease Control and Prevention data show that in breakthrough cases of the highly transmissible delta variant, the answer is no. One of the most nagging questions about the COVID-19 pandemic for public health authorities, policymakers and the public was whether the vaccines stop transmission.
