How many vaccines on the US schedule are unnecessary, and why? There doesn't seem to be any cumulative ill effects of vaccine uptake, despite antivaxx propaganda to the contrary.
The only major difference I see between US and Australian schedules is the omission of chickenpox in Australia. As my 92-year-old mother has been suffering from severe shingles for the past two months (the latest shingles vaccine was unavailable here until the beginning of the year), I am very much in favor of earlier vaccination. Chickenpox doesn't seem to have any animal vectors, so eradication of this virus is possible - although complicated by long term persistence of the virus afer infection.
