Peak anti-vax for measles was like two decades ago, at least over here in the UK - we were at pretty much an all-time record high for MMR vaccinations of kids before Covid came along and disrupted all the vaccination programs. (I know the BBC ran a very misleading article making it sound like Facebook was causing a vaccination crisis and putting us at risk of a measles outbreak, but in reality the actual danger is from all the people who weren't vaccinated years ago due in part to their own bad reporting.)

What is the fraction of the population who is anti-vax with regard to measles? I don't know anyone. I do know many people who are reluctant/refusing to get the COVID vax.
