Close to 85% of people hospitalized with COVID-19 said that they were not back to their pre-COVID lifestyle 1 month later, says the study.

Investigators created models which estimated the number of COVID-19 deaths and cases that would have occurred if the early vaccine campaign had never happened.

Health care workers were significantly more likely to become infected and have severe symptoms, the study found.

The first official case may have been recorded January 20, 2020, but recent evidence suggests that COVID came home for the holidays in the U.S. in mid-December of that year.

The most poorly fitting mask can almost double the risk of infection for the wearers and even those around them.

Investigators developed a sensor system that amplifies the binding signal for a target biomarker in order to detect the presence of a virus.

In the study, cotton masks stopped 45%-73% of coronavirus aerosols. Masks with nanofiber filters blocked 99.9% of the particles.

Ultraviolet-C light makes benzalkonium chloride, which is found in many disinfectants, safer to use.

Individuals vaccinated against COVID-19 do not need to wear a mask outdoors when in small groups, when dining outside, or when biking or running, the CDC announced. However, face-covering precautions should still be taken in some settings.

The inspection was initiated after reports had come to the surface that workers at the plant had accidently contaminated J&J doses with the virus from the AstraZeneca vaccine, which is also manufactured there.

Unlike traditional forms, Moderna’s mRNA-1273 vaccine does not put weakened or inactivated germs inside the body. Rather, it teaches cells to make proteins that will trigger an immune response by injecting ribonucleic acid into cells which gives them instructions.

Moderna’s phase 3 trial data about its messenger RNA (mRNA) vaccine will be presented tomorrow to the FDA’s advisory panel of experts who could then grant an emergency use authorization.
