LONDON — Britain’s main doctors’ organization says it is concerned about the U.K.’s decision to give people a second dose of coronavirus vaccine up to 12 weeks after the first, rather than the shorter gap recommended by manufacturers and the World Health Organization.
The U.K., which has Europe’s deadliest coronavirus outbreak, adopted the policy in order to give as many people a first dose of the vaccine as quickly as possible. So far almost 5.5 million people have received a first dose of either a vaccine made by Pfizer or one developed by AstraZeneca.
AstraZeneca has said it believes a dose of its vaccine offers protection after 12 weeks, but Pfizer says it has not tested the efficacy of its jab after such a long gap.
The British Medical Association urged England’s chief medical officer to “urgently review” the policy for the Pfizer vaccine. It says there was “growing concern from the medical profession regarding the delay of the second dose of the Pfizer vaccine as the U.K.’s strategy has become increasingly isolated from many other countries.”
Pfizer says its second dose should take place 21 days after the first. The WHO says the second shots of coronavirus vaccines can been given up to six weeks after the first.
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.

- Wash your hands often with soap and water for at least 20 seconds.
