What to know about getting updated Covid-19 booster, flu shot at the same time

(CNN) — Fall and winter are around the corner, which means not only is it time to get your flu shot, but US health officials are urging everyone who is eligible to get their updated Covid-19 booster, too.

The US Centers for Disease Control and Prevention recommended the updated Covid-19 vaccine boosters this month, after the US Food and Drug Administration’s authorization. The updated Pfizer/BioNTech booster is authorized for people 12 and older, and Moderna’s is authorized for 18 and older.

At the same time, health officials stress the recommendation to get your seasonal flu vaccine. Some disease forecasters worry that the upcoming flu season could be a tough one for North America, as nations in the Southern Hemisphere that already had their flu seasons — like Australia and New Zealand — saw higher-than-average peaks in cases. So, the United States could see flu make a comeback while Covid-19 is still circulating at higher levels.

Barring any new and concerning coronavirus variants, some officials predict that the updated Covid-19 shots could be the start of recommended boosters for Americans each year, similar to how updated annual flu vaccines are given.

“For a majority of Americans, one shot a year will provide a very high degree of protection against serious illness, and that’s what we’ve got to be focused on,” Dr. Ashish Jha, White House coronavirus response coordinator, told CNN last week. “Maybe for some high-risk people — the elderly, the immunocompromised — they may need protection more than once a year, but for a majority of Americans, that’s where it is, and I think that’s a really good place to be.”
