The describe this finding as "baffling" and call for better purification and quality control, given that many of the contaminants were capable of causing health problems.

I'm not actually sure why they vaccinate for MMR at one year as opposed to earlier like other vaccines. There must be a good reason.

[1] Except when they're broken, and then it sucks bad, and you find out how damn amazing they are and how much we take them for granted.
You can receive a first MMR dose earlier than 12 mos for certain grounds (e.g. international travel, military postings) but it is then recommended that the infant receive a second 'first dose' after 12 months.
Also, it is a relativly recent development that adult humans can even digest milk. Lactose tolerence is the mutation, and a sizable portion of humans do not have it.
By the way, our kids are protected for a while yet by their mothers' immunity to measles (of course that implies mum having either been vaccinated or having had the measles themselves).
The probability of your child getting measles and dying is below most other risks that you take for granted each day.
A child being severely sick for extended periods can be really expensive. Especially for those countries like the US which don't have universal healthcare.
And of course there are long term complications that can result in children becoming deaf or having an intellectual disability: https://www.cdc.gov/measles/about/complications.html
If we're comparing with car accidents, I assure you: Injuries from a traffic accident will in general be much more expensive than measles treatment.
You take steps to minimize unavoidable risks like car travel (e.g. use car seats), but it ultimately you need to travel to function in society.
Measles is a completely avoidable risk. Vaccination and ultimately herd immunity provides a 100% level of protection against measles. We were close to eradicating it.
You also forgot to mention that about 1-2 in each thousand with measles developed encephalitis and 1 in 1000 developed post-infectious encephalitis and that 1 in 20 gets pneumonia.
This is not a small thing.
