Vaccinations

So I am a believer in vaccinations but something terrible happened to my friends baby. A couple days ago her baby got the MMR vaccine and was drowsy all day. She couldn't even get her up to eat. The next morning was found dead in her crib. She's trying to file a lawsuit against the doctors but they ruled it to be a case of sids. Her child was perfect fine and happy before she got this shot. I fully vaccinated my first child and she's perfectly healthy. My newborn just turned a month and got her hep b shot today and I'm freaking about about all her other vaccinations because of what happened to my friends baby. She's devestated and warns me not to get the mmr. Makes me so scared.
