It's actually imperative that younger people get vaccinated as they are more mobile and more likely to spread the virus.
And also because the virus is most likely to mutate inside an unvaccinated person. It takes time for the immune system to respond and develop the appropriate anti-bodies naturally, giving the virus time to replicate and possibly mutate.
