Too Late for a Flu Shot?

Those Who Should Not Get a Flu Shot

Certain circumstances would prevent a person from getting the flu shot. If your child falls into any of the groups below, talk to your doctor to see if a flu shot is recommended:

• infants under 6 months old
• anyone who's ever had a severe reaction to a flu vaccination
• anyone with Guillain-Barré syndrome (a rare condition that affects the immune system and nerves)

In the past, it was recommended that anyone with an egg allergy talk to a doctor about whether receiving the flu vaccine was safe because it is grown inside eggs. But health experts now say that the amount of egg allergen in the vaccine is so tiny that it (but not the nasal mist) is safe even for kids with a severe egg allergy. This is especially important during a severe flu season, such as the current one, which started earlier and has been much worse than in years past.

Still, if your child has an egg allergy, he or she should get the flu shot in a doctor's office, not at a supermarket, drugstore, or other venue. And if the allergy is severe, it might need to be given in an allergist's office.

If your child is sick and has a fever, talk to your doctor about rescheduling the flu shot.

A non-shot option, the nasal mist vaccine, is now available, but because it contains weakened live flu viruses it is not for people with weakened immune systems or certain health conditions. The nasal mist vaccine is only for healthy, non-pregnant people between the ages of 2 and 49 years. Check with your doctor to see if your child can — or should — get this type of flu vaccine.

Are There Side Effects?

Most people do not experience any side effects from the flu shot. Some have soreness or swelling at the site of the shot or mild side effects, such as headache or low-grade fever.

Some people who get the nasal spray vaccine also may develop mild flu-like symptoms, including runny nose, headache, vomiting, muscle aches, and fever.

Where Can My Family Get Flu Shots?

Flu shots are available at:

• many health care settings, including doctors' offices and public, employee, and university health clinics
• some pharmacies
• some supermarkets
• some community groups or centers
• some schools

If you have an HMO insurance plan, be sure to check with your primary care doctor before having your kids vaccinated outside the office, since most HMOs will pay for shots only if they're given through their plan.

Flu shots are covered by Medicare for senior citizens and are generally covered by insurance for people in other high-risk groups. Otherwise, flu shots may cost anywhere from $10 to $50. If you opt for the nasal mist flu vaccine, check to see if your insurance plan covers it.
