- Experts are predicting a strong flu season in the United States as COVID-19 restrictions ease and people venture out more.
- They say adults over age 65 should get one of the stronger doses of flu vaccine available.
- They say older adults need the extra protection because their immune system isn’t as effective against the flu virus as younger adults.
Three new “extra strength” flu shots are now available for people ages 65 and older.
Experts are saying the new flu shots are coming out just in time for what’s predicted to be the worst flu season in years.
According to the Centers for Disease Control and Prevention (CDC), research has
- Fluzone High-Dose Quadrivalent
- Flublok Quadrivalent
- Fluad Quadrivalent
Like standard-dose flu vaccines, these new flu shots are designed to protect against four of the more likely flu strains to spread this season.
The difference between the two types of shots is the total amount of antigens (immune system activators). Each new vaccine has four times the standard dose.
Dr. Barbara Bawer, a family medicine physician at The Ohio State University Wexner Medical Center, tells Healthline adults ages 65 and older need a higher dose of the flu vaccine because with age the immune system often weakens and does not build up enough of a response to the regular vaccine dose.
Dr. Phillip Kadaj, a Michigan-based internal medicine physician and medical expert for JustAnswer, explains that antigens are the immune system activating substances in the flu vaccine.
Bawer adds that if you’re over 65, getting a stronger dose of the flu shot is now what’s required to protect against contracting the flu and reduce the likelihood of becoming severely ill from the flu and requiring hospitalization.
These assertions are backed up by a
Experts suggest the stronger dose of vaccine is coming at a critical time.
However, according to a survey from the National Foundation for Infectious Diseases (NFID), more than half of U.S. adults may be considering skipping this year’s flu shot.
Experts say that’s a problem.
They note that the flu shot is still the most effective way to prevent illness and severe symptoms.
And while the past few years have seen lower-than-average recorded flu levels, change is coming quickly.
Bawer says if we want to know what to expect this flu season, we can look at Southern Hemisphere countries such as Australia.
Australia is a predictor of what could come in the United States, says Bawer, and that country had its worst flu season in five years.
Kadaj agrees with the prediction of a severe flu season, saying he expects flu cases will become more prevalent again as COVID-19 infections have become less serious and people venture out more.
“As COVID-19 infections have become milder and we have effective vaccines for COVID-19, we should start to see an uptick in flu cases,” he says. “I would expect the flu cases this year to reach or get close to pre-pandemic levels.”
Bawer recommends people over 65 get their flu vaccine no later than by the first week in November and ideally in the last two weeks of October. Getting the shot any earlier than this may mean decreased immunity by the season’s end.
“Getting your shot now will give you enough protection from the strains in the vaccine to cover you during the peak flu months and 1 to 2 months on either end as well,” explained Bawer.
Bawer explains the pandemic’s previous impact on flu rates.
She says mask mandates since 2020 have made people more vigilant in their use of hand sanitizer and washing hands more frequently and thoroughly, which has lowered influenza rates across the board.
Also, people have been more cautious about attending gatherings, including holidays, so we have not had as many cases of the flu in the past two years.
“This is both wonderful and problematic,” Bawer says. “Wonderful, of course, because this means a healthier population from a flu standpoint, but this also means that we have much less or little data on the types of flu strains that are out there.”
“But now we no longer have mask mandates (except primarily in health care settings), and people are tired of avoiding loved ones over the holidays and missing out on events in general,” she said. “The combination of the two will yield possibly severe results.”
Experts say you can get vaccinated against the flu and receive a COVID-19 vaccine booster at the same time.
“When the pandemic first started, and the COVID-19 vaccines were brand new, we did not have enough information to know what type of side effects to expect,” says Bawer. “Therefore, we recommended a window between the COVID-19 vaccine and others to give time for people to show any side effects and learn what to expect.”
“More than two years into the pandemic and we now have that information,” she noted. “In many ways, this makes it no different than getting multiple booster vaccines at once or when kids get multiple vaccines during their well-child checks.”
Kadaj agrees, saying the two shots are perfectly fine to do together, but he does caution his patients saying that they may have more side effects.
Common and temporary symptoms from vaccines, says Kadaj, include:
- Body aches
- Muscle pain
“The reason [for caution] is that these patients are simply getting more antigen/immune activating substances at one time,” he says.
So, for example, someone may have a reaction to flu or COVID-19 vaccines, but when they are combined, the reactions are stronger and more likely, he says.
Nonetheless, he says getting vaccinated against COVID-19 and the flu is the best method of protecting yourself and your community from experiencing severe illness.
