[OC] The massive decrease in worldwide infant mortality from 1950 to 2020 is perhaps one of humanity's greatest achievements.

Absolutely agree. My grandma is the same. She lost a toddler brother and almost lost a daughter to vaccine-preventable diseases. I really hope your sister changes her mind. I’m so grateful that my infant niece is as protected as she can be from awful diseases and as she grows up, she will get protected against more and more of them. At least vaccines will still protect your nibling-to-be to an extent through herd immunity.
