The FDA is set to rule on Pfizer boosters on Friday. Some scientists say they aren't needed for healthy people and the doses would more helpful for the unvaccinated in countries with limited supplies.

That's how some scientists describe the findings of a series of studies looking at the antibodies created by individuals who were infected by the coronavirus and then had an mRNA vaccine.

With boosters shots rolling out soon, the big question is: Am I still protected against COVID-19 if I've only had two doses of the vaccine? Turns out, you may have more resilience than you think.

New studies look at how the mRNA vaccines affect the cells in your body in the short run and the long run. The findings are a counterpoint to concerns about waning immunity.

Public health figures believe a focus on boosters for the already vaccinated will hasten the emergence of new variants among the billions of unvaccinated people — including a vaccine-resistant strain.

A leaked CDC document compared it to the highly contagious children's disease. Data does not support this claim. Nonetheless, the variant is one of the world's most contagious respiratory diseases.

The CDC has published new information about how dangerous the delta variant is and the risk it poses to unvaccinated people. The research also indicates that vaccinated people can spread the variant.

A study from China offers clues as to why the delta variant of the coronavirus is spreading so quickly around the world. The highly contagious strain accounts for more than 80% of U.S. COVID-19 cases.

One of the scientists who signed a recent letter calling for more investigation of the lab-leak origin theory says new data has come to light. And that information has changed his thinking.

New analyses of the early days of the COVID-19 pandemic suggests the pandemic may have been spreading from inside the Huanan Seafood Market two months before doctors detected the first cases.

New research from China suggests people infected with the delta variant have, on average, about 1,000 times more virus in their respiratory tracts than those infected with the original strain.

20 years ago, scientists began to study a mysterious emotion known as awe. Now they believe awe offers a range of benefits when practiced regularly, calming our nervous systems and relieving stress.

A coronavirus variant is spreading quickly in India, causing a massive surge in cases. Scientists are rushing to see if vaccines will be effective against this variant. So far, the news is hopeful.
