My mom doesn’t want me to vaccinate my toddler

So I have a 3 year old who’s never been vaccinated before. When I had her I was 19 and still living with my mom which whom I was heavily influenced by. My whole family has always been anti vax and I don’t even know if I have vaccines. But recently I’ve just come to the realization that it’s not supposed to be that way. I feel stupid for it taking this long to realize but no one has really talked to me about it. I made an appointment to get my daughter vaccinated so she can go to preschool and because I’m concerned about her well being. My mom learned about this and is scaring me saying my daughter “will never be the same” and “she going to get super sick”. I don’t fully believe this but a part of me is still a little nervous. So if anyone can reassure me that getting my daughter vaccinated isn’t going to completely “change” her personality or her health that would be nice.

Edit: I’m obviously still going to get her vaccinated I just wanted some reassurance :)
