$BNTX 100% safe. My kid took her first shot and she just got a sore arm for sometime . She is totally fine . Her friends who are younger some had fever that’s all it is . But now we have some relief my kids are protected and they can protect others . Those people who hesitate or hate vaccines , remember they are not only for you it’s for the safety of the people around you. Unless you want to wear mask your entire life. If you are not vaccinated you are welcome … it shows how selfish you are … I don’t want a selfish person next to me .
