Ask a health care provider when the most effective time is to get your annual flu shot, they usually’re prone to let you know that it doesn’t matter when it you get it—simply that you simply get vaccinated.

However there’s a candy spot to optimize your immunity.

When is the optimum time to get the flu shot?

Flu season lasts from October to Might, and instances within the U.S. peak from December to February. That’s why the U.S. Facilities for Illness Management and Prevention recommends that individuals get their flu vaccine by the tip of October, because it takes the immune system about two weeks to rev up its most response to the vaccine. This implies producing enough immune cells—together with antibodies—in opposition to the virus. “The proper time to get vaccinated in opposition to flu is correct earlier than instances begin to take off,” says Dr. Kawsar Talaat, affiliate professor in worldwide well being on the Johns Hopkins Bloomberg Faculty of Public Well being.

However the actuality is that pharmacies, clinics, and medical doctors’ places of work cannot accommodate everybody flooding in on the identical time. So if you happen to’re on the pharmacy and there’s no line in September, there’s no cause to not get vaccinated.

“We’ve seen flu flow into as early as October, so it’s not too early to get vaccinated now,” says Talaat. And whereas safety from the vaccine begins to wane after three to 4 months, “it doesn’t go right down to zero.” Even when your safety begins to fade, you’ll nonetheless be protected.

There are some exceptions to that steerage, says Dr. Robert Jacobson, professor of pediatrics at Mayo Clinic. Kids underneath 9 years previous who’re getting vaccinated for flu for the primary time want two doses, spaced a month aside. For them, beginning in late July or August is sensible, particularly if mother and father need their youngsters to be vaccinated earlier than the beginning of the college yr. Anybody age 65 or older must also take into account getting vaccinated in late summer time as properly, since influenza does begin circulating then and older individuals are at increased threat of growing issues, being hospitalized, or dying from the flu. Lastly, pregnant girls of their third trimester must also take into account getting vaccinated in July or August, so their our bodies can move on protecting antibodies to the child in utero. This safety is essential since infants typically don’t get their first flu vaccine till they’re about six months previous. If they’re born through the flu season, the safety they obtain from their moms serves because the strongest protection in opposition to influenza of their first few months of life.

How efficient is the annual flu shot?

That relies on the yr. Every spring, well being consultants predict which influenza strains can be circulating and inflicting illness, giving producers sufficient time to incorporate them within the vaccines. Typically, says Talaat, if the shot is an effective match with circulating strains, then you possibly can anticipate your shot to guard you from getting flu about half the time. And if you happen to do get contaminated, you’re extra prone to have a milder bout of illness than if you happen to hadn’t been vaccinated. You are additionally much less prone to be hospitalized or die from influenza: dangers that particularly have an effect on older individuals.

Research present that being vaccinated in opposition to the flu can shield you from different well being points as properly, similar to coronary heart assaults and strokes. Flu infections can worsen irritation, which may contribute to coronary heart illness and different situations.

Even with waning, the vaccine continues to offer good safety, says Jacobson—sufficient that well being officers don’t advocate that older individuals who get vaccinated in late summer time, for instance, get boosted with one other dose later within the season. “We take into account them protected for the season,” he says. Plus, individuals age 65 and older typically obtain considered one of a number of stronger flu vaccines to generate probably the most sturdy immune response; considered one of them consists of 4 instances the quantity of immune-activating flu antigens. “They’re protected and efficient, and for individuals over 65, they’re the best way to go,” says Jacobson.

Can I get the flu shot and COVID-19 vaccine on the identical time?

Sure, and also you should not hesitate to take action. Talaat has carried out a examine displaying that individuals getting each pictures didn’t report any extra uncomfortable side effects—similar to sore arms, muscle aches, or fevers—than individuals who obtained them at completely different instances.

And for individuals questioning if getting the 2 pictures on the identical day may someway yield weaker immune responses to each COVID-19 and influenza, “we’ve not discovered any interference with flu and COVID-19 vaccines,” says Jacobson. By not getting the vaccines on the identical day, “you aren’t doing all of your immune system any favors.”

Even if you happen to’ve already had the flu, or if it’s later within the season (say January or February), it’s not too late to get vaccinated. There are normally a number of strains of influenza causing-disease, and the shot would shield you in opposition to the strains you haven’t gotten but. In truth, flu vaccines generate a extra wide-ranging immune response in opposition to a number of influenza strains included within the shot than a pure an infection would, because the an infection is just a single pressure of the virus. “This can be a good instance the place pure an infection is not so good as vaccination, and positively not as protected,” says Jacobson. “Our vaccines today are refined and designed to work with one another, and we’ve good proof that they’re protected and efficient. Get all of the vaccines you’re due for.”
