A few things:

1. We were never guaranteed it would prevent transmission, the original trials were against symptomatic disease. Transmission data was gathered in real time as vaccines were given, and it's an imperfect science anyway. Many vaccines don't stop transmission including the inactivated polio vaccine.

2. We will always be a step in behind in vaccine updates because of the regulatory process, we updated vaccines to BA.5 and now XBB.1.5 is dominant. It's going to be this way.

3. It's not an argument, it's a fact it has reduced burden all you have to do is compare hospitalization rates for those vaccines and those not. Unfortunately many people don't understand base rate fallacy.

4. The increased risk of myocarditis has been acknowledged by every major health body. You know what else causes myocarditis, viruses. The flu can cause it. We know COVID-19 causes it.

5. The virus will continue to mutate away from immune responses. Herd immunity is definitely not here in the way many people use the term.
