What is the flu?
The flu, or influenza, is a highly contagious viral infection that affects the respiratory system, including the nose, throat, and lungs. Common symptoms include fever, chills, cough, sore throat, runny or stuffy nose, body aches, fatigue, and sometimes nausea or vomiting. According to the National Institutes of Health (NIH), “Each year, up to 1 in 5 Americans are laid low by the flu. Most get better within a week, but for some the flu and its complications can be life-threatening.” [SOURCE: https://www.nih.gov/about-nih/what-we-do/nih-turning-discovery-into-health/influenza ]
Should I get vaccinated?
The US Centers for Disease Control CDC recommends the flu vaccine for nearly everyone over the age of 6 months. Getting a flu shot significantly decreases your chance of becoming seriously ill with the flu and makes it less likely that you’ll spread the infection to others.

High risk groups include seniors over the age of 65; people who suffer from chronic illnesses; people who live in nursing homes/long-term care facilities; pregnant women and new mothers.

Your doctor can also tell you if you are someone who should not get a flu shot, for example due to a rare health condition or allergy to an ingredient in the vaccine.
I got a flu shot last year. Why do I need one again this year?
There are several strains of the virus that causes the flu, and the strain changes from year to year. Vaccine manufacturers adjust the flu shot annually so it is optimally effective against whatever strain is circulating. Also, the flu shot wears off over time. Scientists hope to one day develop a permanent flu vaccine, but no current vaccine offers protection for more than one flu season.

There are different versions of the flu vaccine. Which one should I get?
According to the US Centers for Disease Control (CDC), if you are an adult under the age of 65 there’s no benefit in choosing one flu vaccine over another. If you are over 65, however, certain versions of the vaccine are preferred. Whatever you age, consult with your doctor to make sure the flu shot is appropriate for you based on your overall health and any risk factors you may have.

Can I still get the flu if I get a flu shot?
The flu vaccine significantly reduces your risk of getting the flu, but it does not offer 100% protection. Public Health experts estimate that the flu shot is 40%-60% effective in preventing the disease. If you do get the flu after you’ve had the shot, your symptoms will be less severe, and there is much less chance that you will pass along the flu to someone else.

Will I experience side effects?
Some people experience side effects after getting a flu shot. You may experience headache, a slight fever, or muscle aches. Side effects are usually mild, however, and they go away after a couple of days. The possible side effects may be the reason why some people mistakenly believe that getting the flu shot gives you the flu.

Can I get a flu shot and other vaccines at the same time?
Yes, you can get other vaccines, like the COVID-19 vaccine, at the same time you get your flu shot. Getting more than 1 vaccine at a time may slightly increase your chance of experiencing side effects, however. When you consult with your doctor about vaccines, ask her/him which annual vaccines you need and whether it’s advisable to get more than one of them at the same time based on your age, overall health, and any risk factors.
