Totally worth it IMO to come to the States for the vaccination. After a disastrous Covid year, the vaccination system is totally working. Nearly everyone I know in the US has gotten at least one shot (go for the dual shot if you can take the time...Pfizer is quicker of course, three weeks instead of four). Everyone 16+ is eligible starting next week, and appointments are available. It’s nice to feel some hope again and see that the system is actually working.
