Three U.S. universities are among the institutions that are developing a universal COVID-19 vaccine to help fight future coronavirus variants.

New research sheds light on the length of time the coronavirus remains infectious after becoming airborne.

According to the CDC, new hospital admissions for kids with COVID-19 have increased 66 percent on average. Experts explain what parents should know.

The Centers for Disease Control and Prevention (CDC) has published new data finding that getting a third COVID-19 vaccine dose, or booster, provides tremendous protection against getting seriously ill with Omicron.

Experts say the benefits of COVID-19 vaccines far outweigh the risks associated with heart conditions such as myocarditis.

The majority of vaccinated people who have received a booster shot and still contract SARS-CoV-2 will likely experience mild symptoms such as sore throat, headache, congestion, and depending on the variant, coughing and loss of taste or smell.

There's “no evidence right now” that healthy children and adolescents need a booster dose to augment their COVID-19 vaccinations, according to WHO chief scientist, but CDC recommendations differ.

Infectious diseases specialists believe that on average the vast majority of people who contract the coronavirus are most contagious immediately before and immediately after symptoms appear. But how long people are contagious for varies from person to person, depending on the severity of their infection, the intensity of their exposure, and the response of their immune system.

The White House is launching programs to distribute 500 million free at-home COVID-19 tests and 400 million free N95 face masks.
