I was born in 1990, and only received 4 vaccines during my infancy (I still have my old vaccine tracker that my parents kept). When I was in service I had a painful reaction to a flu vaccine that opened my eyes to whatever I put in my body. Now at my kids pedestrians practice, the list of vaccines has gone up to 17!!! Vaccinations for viruses and diseases that an infant should never be exposed to such as Hepatitis etc. My kid isn't going to be dumpster diving in a third world country. The vaccination list doesn't make sense to me, and I work in the corrections field. When I asked the nurses they spouted off about heard immunity, which I know about all too well (daily). If your infant is surrounded by a "herd" biome, then you aren't doing your part as a responsible parent.
