Sounds a bit like you were searching for an excuse for a conclusion you arrived at already for other reasons.
The bulk of advances predate either development of widespread vaccination (largely 1930s - 1960s), or antibiotics (1940s), to say nothing of organ transplants (1950s-), cancer treatments (roughly same), imaging (1900s-), and advanced laproscopic surgeries (1970s-).
Basic sanitation (sewerage & solid waste), water purification, food safety, vector control (mosquitos), physical safety (falls, streets/transport, machinery), environment (soot, lead, asbestos, poisons), habits (smoke, drink, drugs), childbirth & childcare, sex ed, nutrition, and simple basic access to medical care count for far more.

I'm not disputing that vaccines are a powerful and beneficial tool, but that "the greatest life-saving achievement of modern medicine" is not in fact vaccination, but basic (and often quite pedestrian) public health measures.
This has been Laurie Garrett's thesis since at least the mid-1990s. And yes, she's also a strong vaccine advocate:

However, I will decide on yearly flu shots and others based on my own analysis, as clearly government sources have other things in mind that my best interest.
For example, I will wait 6 to 12 month after a covid vaccine is available to check postmarket studies.
A counter example is papillomavirus and shingles (vzw) vaccines, that I have decided to get, even if it's not recommended for me.
