People with COVID will be able to return to school, work and society if they have been fever-free for 24 hours and their symptoms are mild and improving.

Longer summers, rising temperatures and ticks’ expanding geographic ranges are leading to an increased chance of human exposure to pathogens, experts say.

Extra vaccine shots for millions of Americans with weakened immune systems are expected to be authorized within days or weeks.

Officials say the benefits of the vaccines far outweigh risks and ‘strongly encourage’ vaccination for those 12 and older.

A Blue Cross Blue Shield analysis in late 2020 found a 26% drop in vaccine doses among children since the pandemic began.

A study showed that nearly one-third of teenagers hospitalized with COVID-19 during a surge of cases early this year required intensive care, and 5% required mechanical ventilation.

The CDC’s real-world findings provide reassurance about the effectiveness of the Pfizer-BioNTech and Moderna vaccines in the highest-risk age group.

In a study of about 4,000 health-care personnel, police, firefighters and other essential workers, the Centers for Disease Control and Prevention found that the vaccines reduced the risk of infection by 80% after one shot.

Some essential information that would show response effectiveness is not being reported at all.
