I'd consider MMR an essential vaccine. Although it doesn't happen often, Measles does have a risk of Subacute Sclerosing Encephalitis, which isn't a friendly complication. Mumps risks sterilizing your kid, and Rubella is really only a major risk if you plan on having future kids (since Rubella is a classic TORCH infection that negatively affects pregnancy). The supposed link with Autism is questionable at best; Measles infection during pregnancy has more of a link with Autism, which really gives more argument towards vaccinating than not.
I'd consider the injected Polio vaccine essential. No sense in risking paralysis in your kid when it's avoidable.
TDap is probably essential, largely for the Tetanus and Diphtheria (though the rest of the country's herd immunity might make the latter less risky). The Pertussis is sort of weak and would require Azithromycin meds if your kid is exposed, even if vaccinated.
HiB is something I'd consider essential, since it is a pretty serious cause of meningitis that focuses on kids on elderly. HiB meningitis likes to result in deafness and seizures, so again if it's something preventable I'd do it.
I don't think HepA and HepB are essential. I don't think Influenza or Pneumococcus are essential. Rotavirus and Neisseria aren't essential. HPV isn't essential. I probably wouldn't find the Chicken Pox vaccine totally necessary, though your kid might look back when he's older and be thankful when he never breaks out in Shingles. Chicken Pox does rarely sometimes lead to Encephalitis and Pneumonia, and it is a problem if a pregnant woman is exposed to the virus. Those are the only real benefits I can see from the vaccine. Otherwise your kid should do fine with some Tylenol (not Aspirin) if he ever does get Chicken Pox.
Just my personal opinion, for whatever it's worth to you.
