In the US, all 3 available vaccines (Pfizer, Moderna, Johnson & Johnson) are equally effective -- J&J maybe slightly less, but needs only one dose. At your age, any vaccine is as good as the other. There are no significant differences in frequency or severity of side effects. Elsewhere, the Astra-Zeneca vaccine is somewhat less effective, and some made in China and Russia apparently work poorly.

Either one of the mRNA vaccines (Pfizer or Moderna) is an excellent choice. 95%+ protection against severe disease/hospitalization/ death. These are fantastic numbers for a vaccine! Please consider getting vaccinated ASAP and protect yourself from this nasty delta version of the virus...
