I felt like there was an unnecessary amount of hyperlinks within the article ie: children, adolescent, adult; I'm quite confident the audience understands what these terms are so there isn't a need to link these terms to another wikipedia page explaining what it is. I also noticed that you hyperlinked the same term several times throughout the article ie: vaccine; once you have linked it once I don't think it is necessary to link it again. I felt as if you could change the diction and structure of your article so that its more of an encyclopedia article
