My mother had to have the shots with me and my brothers and they are safe
The injection burns pretty bad when you're getting it and it hurt for a few days afterwards but I didn't notice any side effects other than the slight discomfort..
I've heard because I'm O- that the dosage/medicine a bit different but im unsure
I had a weird sharp pain in my back for a couple of days after and was VERY sleepy for a couple of days. But that's the only bad symptoms I had and they were manageable. dont worry too much about it, most women don't have any side effects. I'm particularly sensitive to vaccinations.
I'm A- I had it with my first son and with this one and in completely fine
