Question:

My 6-year-old child recently caught Influenza A. We couldn't get the flu vaccine beforehand due to personal reasons. Should we still get the flu shot now, or is it unnecessary since they already had the flu? The symptoms weren't too severe this time. They have received the flu shot every year since infancy but unfortunately seem to catch the flu every year regardless. Thank you!

Answer:

Hello! I understand your concern regarding the flu vaccine after an Influenza A infection. It must be frustrating that your child catches the flu despite annual vaccinations.

I strongly recommend proceeding with the flu vaccine. Here is why:

• Even though your child recovered from Influenza A, they still need protection against Influenza B.

• The current seasonal flu vaccine protects against four strains: two types of Influenza A and two types of Influenza B.

• Catching one strain does not provide immunity against the other strains circulating this season.

• The vaccine offers broader protection compared to natural immunity alone.

When to get vaccinated:

• The vaccine can generally be administered about two weeks after a complete recovery from the flu.

• Ensure your child is completely fever-free and has returned to their normal energy levels before getting the shot.

• It is recommended to get vaccinated as soon as they are fully recovered, as the flu season can last until May.

Special considerations for your child:

• Group environments, such as school or academies, significantly increase the risk of exposure to different viruses.

• If your child tends to catch the flu annually, vaccination remains crucial. While it may not prevent the flu 100% of the time, it significantly reduces the severity of the symptoms and helps prevent serious complications.

When you visit your pediatrician for the vaccine, please mention the recent Influenza A infection and consult with them to make a final decision on the exact vaccination timing. Wishing your child continued health!
