Important differentiating factor from Pfizer’s vaccine:
“... Moderna said researchers had found that its vaccine had a longer shelf life in the refrigerator than previously thought: 30 days, not seven. And it will last 12 hours at room temperature, the company said.”
This will be key I think. When I saw the details of the cold chain required for the Pfizer vaccine I was fairly certain it was only going to be for front-line workers and those with direct access to a hospital, not something distributed at schools and pharmacies.
