I have a friend who wants to give her son the Pfizer vaccine. He is autistic with food allergies. She has friends and family who have gotten the shot with no problems. She said, they are fine. Does this mean they all will get sick later? I don't know what to tell her. Most people seem fine and a few don't. Who knows how her son will react. Is there any sources I can give her to steer away from the vaccine? She said even Foxnews said the vaccine is safe. Thanks
