U.S. President Joe Biden said the Centers for Disease Control is likely to advise that kids who have not been vaccinated against Covid-19 should wear masks when they return from summer holidays to school in the fall.

Life expectancy in the United States fell by a year and a half in 2020 to 77.3 years – the lowest level since 2003 – primarily due to the deaths caused by the Covid-19 pandemic, a U.S. health agency said on July 21.

U.S. Surgeon General Vivek Murthy stood by federal guidance that those fully vaccinated against Covid-19 no longer needed to wear masks, while blaming social media companies for fueling vaccine misinformation.

The U.S. Food and Drug Administration is planning a new warning for Johnson & Johnson’s Covid-19 vaccine over a rare but serious side effect, Guillain-Barré syndrome (GBS).

The U.S. Centers for Disease Control and Prevention on July 9 updated its guidance to help reopen schools in the fall, including recommending masking indoors for everyone who is not fully vaccinated and three feet of distance within classrooms.

Pfizer and partner BioNTech plan to ask U.S. and European regulators within weeks to authorize a booster dose of the companies’ Covid-19 vaccine, based on evidence of greater risk of infection six months after inoculation and the spread of the highly contagious Delta variant.

U.S. Covid-19 cases are up around 11 percent over the previous week – almost entirely among people who have not been vaccinated – officials said on July 8, as the highly infectious Delta variant becomes the dominant Covid-19 strain in the country.

Fewer Americans are dying from the most common types of cancer, especially lung, showed a report published in The Journal of the National Cancer Institute on July 8.

The Delta variant is already the dominant strain of Covid-19 in the United States, according to data modeling done by the U.S. Centers for Disease Control and Prevention (CDC).

The United States had administered 330,604,253 doses of Covid-19 vaccines in the country as of the morning of July 4 and distributed 383,068,740 doses, the U.S. Centers for Disease Control and Prevention said.
