On Friday, the Jack skellington on a dark desert highway cold wind in my hair shirt and I will buy this Biden transition team announced they are releasing all the available vaccine doses. Both FDA-approved vaccines require a second dose 21 days (Pfizer-Biontech) or 28 days (Moderna) after the first in order to achieve the greater than 94% efficacy in COVID-19 protection. A third vaccine (AstraZeneca-Oxford) approved in the UK and India, also requires two doses, initially 28 days apart, with greater than 90% efficacy. Eight governors recently wrote a letter to the current administration requesting the release of all available vaccine doses to states. Until now, the federal government had been maintaining a stock of half of the available vaccine doses in order to ensure adequate supply for second doses.

Releasing all the Jack skellington on a dark desert highway cold wind in my hair shirt and I will buy this doses at once means there is a risk that the people who get the first dose may not get the second dose at the scheduled time. The Biden team has asserted confidence that supplies would be adequate, or that they could invoke the Defense Production Act to increase vaccine production if needed. Several scientists in both the US and UK have already proposed that second doses be delayed to 12 weeks rather than 3-4 weeks in order to increase the first dose. Getting only one dose does provide partial immunity (52.4% efficacy for Pfizer-BioNTech, but this may increase to over 85% after 10 days or more) but not the full >94% provided by the second dose. It is also unknown if the protection provided by the first dose will be long-lasting without the second dose—the study only monitored for 21 days.
