There is no reason you have to give all these at the same time!!! It is up to you! My daughter has had all the vaccines but at a much slower pace. We had the MMR seperated, yes they can special order this! We give her one shot on one day and let her body deal with that. THen 2-4 weeks later we’ll do another. We have never had to give her a stress dose of meds except on 2 occasions when a fever developed. (We chose to not do prevnar, too new and and don’t want mu daughter to be experimented on. It’s not needed for schools in CA.) Make sure you ask the doctor if the vaccines have mercury in them. The new ones don’t but some old batches are still around. Julia
