LONDON -- Britain says it has secured 2 million more doses of a promising coronavirus vaccine as the country aims to launch an inoculation program within days.
The U.K. government has agreed to buy more than 350 million doses of vaccines from seven different producers, should they prove effective.
The Department of Health said Sunday it had increased its order for a vaccine developed by U.S. firm Moderna from 5 million to 7 million doses, enough for 3.5 million people.
British media say hospitals have been told they could receive the first doses of another vaccine, developed by Pfizer, during the week of Dec. 7, if it receives approval from the U.K.'s medicines regulator.
Most patients with COVID-19 have mild to moderate symptoms. However, in a small proportion of patients, COVID-19 can lead to more severe illness, including death, particularly among those who are older or those who have chronic medical conditions.
COVID-19 spreads primarily through respiratory droplets produced when an infected person coughs or sneezes.
Symptoms include fever, cough, and difficulty breathing. Symptoms appear within 14 days of being exposed to an infectious person.
