New CDC data is offering up-to-date insights into the effect of the Delta variant on vaccine effectiveness. The reports indicate unvaccinated people are still 10 times more likely to suffer hospitalization from COVID-19 compared to vaccinated people.

From late September all Americans will be offered a third COVID-19 vaccine booster shot, to be administered at least eight months after a second dose, but some are questioning the need for third shots when so many are still yet to receive even one dose.

The FDA has authorized a third COVID-19 vaccine dose for immunocompromised individuals. The authorization comes after weeks of speculation about booster plans and the FDA stresses other populations do not require extra doses at this point in time.

When will COVID-19 vaccine booster shots be necessary? Pfizer claims a third booster of its vaccine may be needed six to 12 months after vaccination but not everyone is convinced, with new research finding mRNA vaccines may offer years of protection.

Ninety percent of new coronavirus infections in the UK are due to the Delta variant. In the US the CDC warns the variant will become predominant in the coming months. What is the Delta variant, why is it such a problem, and will our vaccines still work?

New studies from the NIH and the CDC have found SARS-CoV-2, the novel coronavirus responsible for COVID-19, was likely circulating around the United States for at least several weeks prior to the first officially reported case in late January 2020.

A CDC report has found less than 1,000 cases of COVID-19 needed hospitalization out of more than 100 million fully vaccinated people. The CDC admits it may be undercounting positive cases, but it's still a reminder of the real-world effectiveness of vaccines.

Striking research estimates the global death toll from COVID-19 could be more than twice as high as official numbers show. Tracking overall 2020 mortality figures from around the world indicates nearly 7 million people may have succumbed to the disease.

A new report from the CDC has found more than three-quarters of people presenting at a hospital with COVID-19 were either obese or overweight. The findings build on a convincing body of research linking disease severity with higher BMI.

A new CDC report says nearly 300,000 more deaths than expected have occurred in the US so far in 2020. Only two-thirds of these “excess deaths” are attributed to COVID-19, suggesting the toll of the pandemic is higher than the confirmed mortality numbers.

A new CDC study has found restaurant dining to be the most commonly shared activity amongst a number of adults with COVID-19. The CDC study suggests eating at a restaurant is an especially high-risk activity during this ongoing pandemic.

A choir rehearsal, a series of family gatherings, and a multi-day church event. Three CDC reports offer detailed insights into super-spreader COVID-19 clusters. Can these reports point us towards safer ways to reopen our communities?
