Moderna's coronavirus vaccine will provide immunity from the disease for at least one year, the biotech company said Monday per Reuters.
Why it matters: Moderna's vaccine is one of two now authorized for emergency use in the U.S., as coronavirus cases surge past 22.5 million nationally and 90.8 million globally.
The big picture: Moderna expects to deliver around 600 million to 1 billion doses in 2021.
- The U.S. has purchased a total of 200 million doses from Moderna.
- The company has signed agreements with several other countries including Japan, Canada and Israel, boosting hope as the number of global cases nears 91 million.
- The United Kingdom and the EU's European Medicines Agency approved the vaccine this week.
Yes, but: The World Health Organization cautioned on Monday that herd immunity is unlikely this year despite the vaccine rollout in countries around the world.
