Did all kids in 70s have measles vaccine?

No, not all kids in the 1970s received the measles vaccine. The measles vaccine was introduced in 1963, but widespread vaccination efforts did not begin until the late 1960s and early 1970s. While vaccination rates increased over the years, many children remained unvaccinated due to factors like public awareness, access to healthcare, and parental choice. As a result, outbreaks of measles still occurred during that decade.
