This video update covers my latest thoughts on the Delta surge, what we’ve learned about the efficacy of COVID vaccination in older adults over the last six months, breakthrough COVID cases, and whether “boosters” will be required.

Note: A day after I recorded my update, the CDC released three additional studies regarding COVID vaccination. You can read about them here. Basically, one study concluded that vaccinated people are 5x less likely to get COVID, 10x less likely to be hospitalized, and 11x less likely to die of COVID.  Another study found that vaccine efficacy is a bit lower in adults older than 75, compared to younger than 75, and that vaccine efficacy was better with Moderna than Pfizer. And a study in veterans found that “vaccine effectiveness in preventing COVID-19–related hospitalization was 80% among adults aged ≥65 years compared with 95% among adults aged 18–64 years.”
