As flu season nears, here’s what you need to know

Last year’s influenza season turned out to be the mildest on record, but health experts have renewed warnings that a ‘twindemic’ — in which flu and COVID-19 cases simultaneously rise and overwhelm hospitals — may be possible this year, and they urge Americans to get their flu shot.

The Centers for Disease Control and Prevention reported 1,675 cases of influenza from Sept. 28 to May 22, representing only .2% of specimens tested.

But it’s difficult to predict what this year will look like, health experts say.

“We were worried about the ‘twindemic’ last year and we face the same threat this year,” said Dr. Daniel Solomon, a physician in the division of infectious diseases at Brigham and Women’s Hospital. “COVID19 is likely to continue, and we face the threat of dual respiratory viruses that could put a strain on our health care system.”

Who should get a flu shot?

The CDC recommends that everyone 6 months and older get a seasonal flu vaccine each year, ideally by the end of October.

Children younger than 5 years old — especially those younger than 2 — are at higher risk of developing serious flu-related complications. A flu vaccine offers the best defense against flu and its potentially serious consequences and also can reduce the spread of flu to others.

When are flu shots available?

Flu shots are available now. A typical flu season in the U.S. peaks between December and February and can last as late as May, according to the CDC.

Can you get both the flu shot and COVID-19 vaccine?

CVS and Walgreens offer co-administration of the COVID-19 and influenza vaccines. The CDC reversed previous guidance to wait at least 14 days between the COVID19 vaccine and other vaccines, saying “you can get a COVID-19 vaccine and other vaccines at the same visit.”

Doctor says get your flu shot soon or risk “super infection” with COVID-19.
