The Trump administration has repeatedly claimed that the U.S. will have millions of Coronavirus vaccine doses ready by the end of the year. Several American companies are currently in Phase 3 of trials and reportedly producing thousands of doses for distribution. In September, pharmaceutical company Pfizer announced they would know if the vaccine works as soon as October 2020. If approved, it's "likely" to deploy a Covid-19 vaccine to the public before the year-end. It expects to manufacture over 1.3 billion doses of their vaccine worldwide by the end of 2021. The other pharmaceutical company leading the race for the vaccine, Moderna, claims to be on track to produce 20 million doses by the end of the year. As California Senator Kamala Harris pointed in the vice presidential debate, questions are being raised on the efficacy and safety of a vaccine that has not undergone the usual period of 12 to 18 months of testing. In July, Dr. Anthony Fauci told the U.S. Congress that he is "cautiously optimistic" that a "safe and effective" coronavirus vaccine will be available to the public by the end of 2020. Meanwhile, the U.S. Food and Drug Administration told coronavirus vaccine developers it wants at least two months of safety data before authorizing emergency use, possibly pushing the Trump administration's plans to have a vaccine out by November.
