How can a high school student contribute to the cause of getting people vaccinated?

You could do a Youtube promo showing you getting the shot, just like the former presidents (except Trump) are doing. You could even become a spokesperson! 

PS - This is not the last public health challenge in your lifetime - there are new diseases every few years. There's never been so much politics around one before. 

Polio was bad when I was a kid, and a lot of kids ended up cripple. My aunt said tuberculosis was bad when she was a kid and she was taken away from her family to a sanitorium. 

Too early to tell. Try again in about 6 weeks. 

By getting vaccinated when it’s available to you.
