All You Need To Know About Flu Shots
How long after flu shot do side effects occur?
Rarely, people who get the flu shot have a fever, muscle pain, and feelings of discomfort or weakness. If experienced at all, these effects usually last for 1-2 days after vaccination and are much less severe than actual flu illness.
Is flu vaccine safe?
The flu vaccine is considered safe. You can’t catch the flu from the vaccine, because the virus in the vaccine has been killed or weakened. The live vaccine isn’t recommended for people with a weaker-than-normal immune system.
Is the flu shot necessary?
Getting an annual flu vaccine is a safe, effective way to prevent the flu. The vaccine causes your body to develop antibodies to several strains of influenza virus. These antibodies help protect your body against infection.
When Should I get vaccinated?
You should get a flu vaccine before the flu begins spreading in your community. It takes about two weeks after vaccination for antibodies that protect against flu to develop in the body, so make plans to get vaccinated early in fall, before flu season begins. CDC recommends that people get a flu vaccine by the end of October. Getting vaccinated later, however, can still be beneficial and vaccination should continue to be offered throughout the flu season, even into January or later.
Children who need two doses of vaccine to be protected should start the vaccination process sooner because the two doses must be given at least four weeks apart.
Who should get the Flu Vaccine?
The Centers for Disease Control and Prevention (CDC) recommends a flu vaccine for everyone 6 months of age and older.
But it’s especially important for those who are at greater risk of developing health problems from the flu, including:
- all kids 6 months through 4 years old (babies younger than 6 months are also considered high risk, but they cannot receive the flu vaccine)
- anyone 65 years and older
- all women who are pregnant, are considering pregnancy, have recently given birth, or are breastfeeding during flu season
- anyone whose immune system is weakened from medications or illnesses (like HIV infection)
- residents of long-term care facilities, such as nursing homes
- anyone (adults, teens, and kids) with a chronic medical condition, such as asthma
- kids or teens who take aspirin regularly and are at risk for developing Reye syndrome if they get the flu
- caregivers or household contacts of anyone in a high-risk group (like children younger than 5 years old, especially those younger than 6 months, and those with high-risk conditions)
Certain things might prevent a person from getting the flu vaccine. Talk to your doctor to see if the vaccine is still recommended if your child:
- has ever had a severe reaction to a flu vaccination
- has had Guillain-Barré syndrome
