Production is about to increase dramatically. Connecticut just announced they will gradually open up eligibility to ages 16+ by May 3rd, which is the minimum age the Pfizer vaccine is currently approved for. I expect other states to follow a similar trend as it's all based on supply.
And tjf, I think that there are multiple factors leading to increased supply, and it's not all due to who's in the White House. Having a president more focused on overturning the election in the first month certainly didn't help things, but it's impossible to know how much effect it really had.
