possibly unwise to leave that up to me to decide, but I'll have a go
In a debate about the efficacy of vaccines 2 years into in a pandemic, possible priorities might be limiting further cases, encouraging people to take precautions for themselves and others, realistic analysis of non-mainstream data (which you seem to be inconsistantly good at), debunking of harmful conspiracy theories... (have you tried any of that?)...
Interesting debate on the Times footie podcast about what young fit pro footballers in bubbles should do, whether they, as a subset, might have more risk from the vaccine than the disease, and if they're bubbled...
You just seemed to lurch from interesting discussion to a random political swipe at Biden as if you really thought he should be held accountable for with/of/or near Covid deaths.
