Jul 14, 2021 · One recent study found that people infected by the Delta variant were roughly twice as likely to be hospitalized as those infected with the Alpha variant. What to Know About the Delta Variant ...
The delta variant is concerning because it's more highly transmissible, but the good news is that the COVID-19 vaccine is still highly protective against getting infected or ending up in a hospital or dying from the infection. Breakthrough infection is a rare event where someone who is fully vaccinated still ends up getting infected with COVID-19.

According to an internal CDC document, the Delta variant – one of four “variants of concern” that have evolved from SARS-CoV-2, the virus that causes COVID-19 – is more than twice as infectious as the original virus and as infectious as chickenpox. Its high infectiousness could be due to its ability to replicate rapidly in the body. A study from Ch...
There’s not yet consensus on whether the Delta variant makes people sicker. The internal CDC document cited studies from Canada and Singapore (not yet peer-reviewed) that found higher odds of hospitalization and death, and a study from Scotlandthat found double the risk of hospitalization compared to the Alpha variant, which had been the dominant v...
Roan’s lab is currently preparing to study the Delta variant, and she is optimistic that the T cell response will hold up. They have already shown that the T cell response is just as strong against the Alpha, Beta, and Gamma variants as it is against the original virus. Roan’s team has also found that T cells may be particularly important in preven...
Jul 16, 2021 · Q: Is the Delta variant more deadly? While an increase in infections alone is troubling and can lead to more deaths—both through the increase in cases and by overwhelming the health system—early research suggests Delta is possibly more dangerous than the Alpha variant and twice as likely to lead to hospitalization.
Aug 6, 2021 · New research holds answers. Studies show that Delta replicates more quickly and generates more virus particles than other variants, but vaccines still protect against serious infections. By...
Jul 30, 2021 · Data from the study indicated that, on average, the Delta variant was 2.9 times less susceptible to neutralization than the Wuhan strain, but most convalescent serum samples and all vaccination serum samples showed detectable neutralization activity.
Jun 22, 2021 · People who are infected by Delta may carry 1,000 times more virus, and for a longer period of time, than those infected by the original virus. Other evidence suggests that the variant may be...
