The UK government has also exercised its option to purchase an additional 10 million doses of the two-dose mRNA vaccine, bringing its confirmed order commitment to 17 million doses. Deliveries are expected to commence in the spring.
It is the third vaccine authorized in the UK, which began vaccinating with Pfizer/BioNTech in December and AstraZeneca this week. Nearly 1.5 million people have been vaccinated to date. The Moderna vaccine is one of the UK's smaller orders (compared, for example, to 100 million doses from AstraZeneca and 40 million from Pfizer), but will nevertheless boost the UK's vaccination campaign once doses are delivered.
For Moderna, it is the fifth vaccine authorization for the vaccine: starting with emergency use authorization in the US on December 18 and then a few days later in Canada, and then with the green light in the EU and Israel this week. Singapore and Switzerland are among the countries reviewing the vaccine.
The vaccine was shown to be 94% effective in Phase 3 trials.
