They may dodge the bullet if they're giving Pfizer and Moderna to their highest risk population (i.e. the elderly and infirm).
The studies of Pfizer and Moderna against the original SARS-CoV-2 showed that risk of infection dropped by 50% within the first 10 days after the first shot. By day 21 (when the boost dose is given), efficacy was nearly 90%. The Delta (India) variant studies are incomplete but the estimates are about 80% efficacy for people who are fully vaccinated (compared to 95% efficacy on the original Alpha virus).
The bad news? The dominant variant in the US is the B.1.1.7 (UK) variant. The Delta variant is doubling every two weeks, so they're estimating that the US numbers for next week will probably be somewhere near 10%. In the UK, Delta is already 91% of cases.
Delta seems to double the risk of hospitalization, so all those anti-vaxxers running around are ensuring that the Delta variant is going to become dominant variant which means more people getting sick (because of the lower vaccine efficacy) and it means that the hospitals aren't going to get a break this summer. It also means that we may end up getting a booster to increase coverage for variants in the Fall/Winter.

Sounds like the US might need to stock up Oxygen to avoid families begging for oxygen ....
