The U.S. has now administered more than 101 million doses of coronavirus vaccine — with almost 20% of the population having received at least one dose and over 10% of the population fully vaccinated.
Why it matters: The milestone comes the U.S. speeds up its vaccine rollout. President Biden on Thursday directed states and tribal governments to designate all adult Americans eligible for a vaccine no later than May 1.
The big picture: Pfizer — the first available COVID-19 vaccine in the U.S. — received its emergency use authorization in December. Moderna received its EUA a few weeks later and Johnson & Johnson got its green light in February. The three vaccines have helped speed up rollout.
- Biden said in early March that the U.S. would have enough vaccine doses for 300 million Americans by the end of May. His previously promised timeline was the end of July.
