Who Needs a Flu Vaccine?

Not long after Labor Day, you’ll start hearing it. “Get your flu shot!” But do you really need to?
Yes. The CDC says everyone over 6 months old should get a flu vaccination every year. It’s the surest way to protect yourself from the flu.
“The flu vaccine stimulates your body to make antibodies,” says Patricia Winokur, MD, a professor of internal medicine and infectious diseases at the University of Iowa. They help your immune system fight flu viruses when you come in contact with them.
You’ve probably heard about someone who got their vaccine but got the flu anyway. It happens, but the vaccine still helps even if you get sick. It makes the illness less severe than it would be without it. People who get a flu shot are less likely to need to go to the hospital.
And even if you’re healthy and not worried about getting sick, get a flu shot to protect your loved ones. Babies, young kids, older adults, and those with chronic health problems can get seriously sick from the flu.
“It provides community protection,” says William Schaffner, MD, medical director of the National Foundation for Infectious Diseases. “You’re much less likely to spread the flu to others [if you get vaccinated]. You don’t want to give it to someone at work, in your family, at the gym, at religious services. We get the flu vaccine for ourselves and also for everyone around us.”
Who Needs a Flu Vaccine?
Just about everyone older than 6 months should get one, but the flu vaccine is especially important for:
• People 65 and older
• Pregnant women
• People with asthma
• Kids younger than 5, especially younger than 2
• People who live in a nursing home
• Anyone with health problems, like diabetes, HIV, cancer, heart disease, or who’s had a stroke
When and Where?
You can get the flu any time of year, but flu season generally lasts from October to May. Get vaccinated before it ramps up, ideally by the end of October. It takes about 2 weeks for your body to fully build up its defenses after the vaccine.
Keep in mind that some kids will need two doses, spaced about a month apart. Better to get them started early.
But if you forget until later in the year, don’t worry that it’s too late to matter. “If there is flu circulating, it’s worth getting it,” Winokur says.
Many doctor’s offices, pharmacies, clinics, and health departments give flu vaccines. Your workplace or school might offer them, too.
What Type Should You Get?
There is more than one way to get the vaccine:
A regular flu shot. This is how most people get the vaccine — through a needle, usually in the arm. It protects against the three or four flu viruses that scientists predict will be most common this year.
High-dose flu shot. Doctors recommend this vaccine for people 65 and older. Because the immune system gets weaker with age, a higher dose gives them better protection against the flu.
Nasal spray. You inhale this vaccine through your nose, no needles required. But some people shouldn’t have it, such as kids younger than 2, adults over 50, and pregnant women. People with some medical conditions also shouldn’t get it, including kids ages 2-4 with asthma. The spray is an attractive option for kids who are afraid of needles, but pediatricians say that the shot is still the best way for kids to get the flu vaccine.
If you have severe allergies to an ingredient in the vaccine, like eggs, antibiotics, or gelatin, talk to your doctor about what to do. There may be other types of the vaccine you can get.
Can It Make You Sick?
You hear it over and over, but the truth is the flu vaccine won’t give you the flu. It’s made with dead viruses, pieces of viruses, or weakened viruses, which can’t give you the flu.
Some people have mild side effects, like soreness where they got the shot, a low fever, or body aches. If you get the nasal spray vaccine, you could get a runny nose or headache.
