Is this flu season the worst?

In the United States, flu season starts in the fall. And even though flu can spread year-round, it's essential to be vigilant during this time. It begs the question – when is the best time to get my flu shot? Thankfully, we have some expert advice about when to get your flu shot.

According to the CDC, flu season starts in the fall but peaks between December and February. According to infectious disease experts at MedStar Health, the best time to get your flu shot is in October. Doing so helps you stay protected throughout the flu season, which can last until May.

Furthermore, COVID has complicated matters. Since the pandemic's start, the timing and duration of flu season have been less predictable. The pandemic practically shut down the spread of the flu over the last two years.

Historically, flu season peaks in February, with nearly equal representation between December, January, and March. NPR reporting suggests that this flu season is poised to be one of the worst we've ever seen. Some parts of the country, such as Texas, are showing us what might be in store.

Who is eligible for the flu vaccine?

Different influenza vaccines are approved for different age groups. According to the CDC, everyone six months of age and older should get the influenza (flu) vaccine every season, with rare exceptions.

Should I get a flu shot every year?

Yes. As the flu virus changes often, the vaccine should be given yearly for the best protection. Immunity to flu from the vaccine decreases with time and should be boosted with a yearly shot.

When is the best time for kids to get the flu vaccine?

Although many get vaccinated before school starts, October is the best time to get your flu shot. Doing so helps you stay protected throughout the flu season (until May). But getting vaccinated ahead of the school year provides greater protection than not at all.
According to a recent MedStar Health survey, the majority of kids get their flu shot, with 80% of kids getting their flu shot every year or most years.

Does the flu vaccine protect against COVID-19?

The flu vaccine will not protect against COVID-19 but will decrease your risk of influenza. Because some symptoms of flu and COVID-19 are similar, people may need to be tested to identify which virus is causing their illness.

What are the side effects of the flu vaccine?

Typically, people might experience a mildly sore arm for a short time. Those receiving the vaccine for the first time experience a mild fever or minor aches lasting about 24 hours.
