In the last few days, the question of why more drug companies haven't been enlisted for vaccine production has come up. It's mostly due to this tweet: The problem is, as far as I can see, this is simply wrong. There are not "dozens of other pharma companies" who "stand ready" to produce these
The article focuses on the mRNA vaccines and I agree with the points mentioned. mRNA vaccines are a (relatively) novel approach and there are not enough capacities to produce enough of it. But vaccines that use more established technology like the AstraZeneca vaccine or Sputnik should be easier to produce. I am curious whether we use all of our available capacities for them.
