Americans waiting on a COVID-19 vaccine get a bit of insight into the distribution timeline.
If Pfizer receives emergency use authorization of its COVID-19 vaccine, doctors hope the first patients will receive vaccinations within a few days of approval. Some even believe it could come as early as December 11 or 12.
Meanwhile, The US government purchases 300 million doses of Aztrazeneca's vaccine. It believes it will play a pivotal roll in the vaccination program in America since it costs less to make and easier to distribute. Pfizer's vaccine must be transported at below zero temperatures in dry ice.
Plus, Johnson & Johnson hopes to publish its COVID-19 vaccine trial results by the start of 2021.
