Would you still get the flu shot in late January?

If you've never had any problems with it before, I would highly recommend it. If you get it at a pharmacy, you will have to fill out a form which asks some basic questions which will guide the pharmacist as to if you should get it. Also, ask the pharmacist what side effects you should expect and not expect. I trust what my reliable pharmacist tell me because they're not doctors and they study the medicines. I will take their advice and ignore anything I read online. I've never had any bad advice and I've never had any bad reactions from anything following these guidelines.
