4 month vaccines

My baby is only 11 weeks but I'm already dreading the 4 month shots she did okay with her 2 month shots but I've been reading a lot about babies dying within a week after the shots due to unknown causes and ruled as sids after their shots and their parents are certain it was because of the shots. Im terrified and a worrier in general and I'm always watching my baby me and my husband take shifts and I'm terrified. What is your thoughts on vaccinating or experiences. Do some ppl hold off? Why or why my get vaccinated? Any advice is appreciated.
