He additionally tried to launch political stress on the vaccine outcomes, saying: “This isn’t going to be a Republican vaccine or a Democratic vaccine. That is going to be a vaccine for the residents of the world. I hope that it will be efficient.”
Because the Instances has beforehand famous, Pfizer’s trial design is without doubt one of the quickest among the many handful of trials furthest alongside—together with trials performed by Moderna, AstraZeneca, and Johnson & Johnson.
