anti flu shot

You don't have to agree but my grandmother has been a nurse for 28 years and always advises AGAINST the flu shot. I've never had one and I've never had the flu. I know a woman who wasn't able to walk for a full year because she had a bad reaction to a flu shot. I definitely won't be getting one while pregnant. Please research before you do whatever the doctor recommends. Just because they say it doesn't mean you have to do it. 
People have survived for generations without a flu shot. Pregnant and all. Plus there's nothing saying the flu shot has been proven safe for pregnant women. 
If you want to get a flu shot, go for it. This post isn't meant for debates or persuasion I just wanted to throw my own opinion out there. 
I won't be replying to comments so don't bother asking direct questions lol.
