I’m not a medical professional, just did a quick search to verify: the first shot wasn’t available for children until 1995, so older generations couldn’t get it during childhood. That shot was only for children, a version for adults over the age of 60 came later in 2006, but was limited in effectiveness. In 2017 a new vaccine was introduced with significantly higher effectiveness for people over 50.
