US regulators have authorized a 3rd COVID-19 vaccine booster for adults over age 18. The recommendations simplify the health advice and infectious disease expert Anthony Fauci urges boosters for all those who are six months beyond their second dose.

A study comparing the effectiveness of three COVID-19 vaccines over eight months found protection from infection declined but protection from death remained strong. Tracking 800,000 US Veterans, the study found the J&J vaccine showed the greatest decline.

An endorsement by Rochelle Walensky, director of the US CDC, is the final regulatory hurdle to be overcome allowing a special pediatric formulation of Pfizer's mRNA vaccine to be administered to children across the United States.

CDC investigators have homed in on an aromatherapy room spray sold at Walmart as the source of a small outbreak of the rare tropical disease melioidosis. The spray contained traces of bacteria known to cause the disease and has now been recalled.

Two studies from the CDC are offering evidence of universal mask-wearing practices in schools reducing rates of COVID-19 outbreaks. The research conducted across July and August delivers insights into how the Delta variant can spread in children.

After weeks of regulatory discussions, COVID-19 vaccine boosters are finally rolling out across the US following the final tick of approval from CDC director Rochelle Walensky. The program only applies to those previously administered the Pfizer vaccine.

How do rapid antigen COVID-19 tests work? Why did the US government just pledge to buy 280 million of them? And is that even enough to help curb the spread of the virus?

An advisory panel to the FDA has voted against recommending a broad COVID-19 vaccine booster program for all American adults at this time. Instead, the panel unanimously recommended boosters for those in high-risk groups or over the age of 65.

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.

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.
