Can you still get flu even if you've had a flu jab?

Can you still get flu even if you've had a flu jab?

My understanding is that this year's flu shot is spot on. Wash your hands. Lg. ...Read more

I had my flu jab on Thursday, it still has a red oval shape around it but doesn't hurt, is this normal?

I had my flu jab on Thursday, it still has a red oval shape around it but doesn't hurt, is this normal?

Not that uncommon: Without seeing and feeling it, it sounds like you just have some local irritation at the injection site, which is common with many different vaccines. As long as you don't have fevers, spreading redness, increasing pain, discharge at the site, you'll likely be fine. Consider cold compresses to speed resolution. But if you are that worried, address this with the doctor who vaccinated you. ...Read more

My 12 months baby got an adult flu shot and a baby flu shot ?

My 12 months baby got an adult flu shot and a baby flu shot ?

Oops!: I assume this was an error. Injectable flu vaccine is a killed virus vaccine. Your baby will not get the flu from it. Because there is more antigen in the adult form of vaccine your baby may have more antibody response--fever, aches, fussiness. If your baby got a multidose vial flu it was likely preserved with some thimerosol. This has a little mercury in it. I would talk to the dr about that. ...Read more

If you know that an individual with whom you are going to be in contact has influenza and you can avoid contact that would be the safest course of action. ...Read more
