TLDW:

• Moderna and Pfizer trials were held during the summer when case counts were low.
• AZ and J&J vaccines held trials in USA, South Africa, and Brazil where covid variants emerged
• AZ and J&J vaccines trials were held later (fall & winter 2020) where case rates were tripled compared to summer 2020 |
Excellent watch. Everyone who tries to "hold out" for their favourite vaccine should be forced to watch it to make an informed decision.
