‘Wonderful news to wake up to’: U.K. greenlights Pfizer’s COVID-19 vaccine | Science

The United Kingdom has bought 40 million doses of the Pfizer/BioNTech vaccine, enough for 20 million people. Health secretary Matt Hancock today announced that the first 800,000 doses will be available next week.

The United Kingdom’s Medicines and Healthcare Products Regulatory Agency (MHRA) announced today it has granted emergency authorization for the COVID-19 vaccine developed by Pfizer and BioNTech. So far, only vaccines developed in Russia and China have been approved for use, and none of them in Western countries.

“It is only 12 months since the first recorded case of COVID-19,” Arne Akbar, president of the British Society for Immunology, said in a public statement this morning. “To achieve this within this timescale is remarkable and the researchers should be applauded.”


The European Medicines Agency, which regulates drugs and vaccines in the European Union, said yesterday that its Committee for Medicinal Products for Human Use will meet on 29 December at the latest to discuss Pfizer’s data. (A similar meeting for its key rival, Moderna, will take place no later than 12 January 2021.) The U.S. Food and Drug Administration (FDA) has a meeting planned to discuss Pfizer’s data in depth on 10 December. The early approval of a vaccine in the United Kingdom may further increase political pressure on FDA to speed up its authorization process; U.S. President Donald Trump has reportedly already admonished FDA Commissioner Stephen Hahn to do so.

It is only 12 months since the first recorded case of COVID-19. … To achieve this within this timescale is remarkable and the researchers should be applauded.

MHRA will only become fully independent on 1 January 2021, following Brexit, but U.K. regulations allow it to grant authorizations on an emergency basis. The United Kingdom has bought 40 million doses of the Pfizer/BioNTech vaccine—enough for 20 million people—and health secretary Matt Hancock today announced the first 800,000 doses will be available next week. The rollout will prioritize health workers as well as the elderly and other vulnerable populations, but the Joint Committee on Vaccination and Immunisation has yet to offer its final guidance on the exact priorities.

Russia on 11 August allowed its COVID-19 vaccine, developed by the Gamaleya Research Institute of Epidemiology and Microbiology, to be used on certain groups of people, and China has granted emergency use authorizations (EUAs) for several vaccines and has already vaccinated hundreds of thousands of people with them. A few other countries, including the United Arab Emirates and Bahrain, have issued an EUA for one of the Chinese vaccines, produced by Sinopharm.

The Pfizer vaccine, whose key ingredient is messenger RNA that encodes the spike protein of the pandemic coronavirus, was found to have 95% efficacy, a clinical trial measurement of effectiveness, in a phase III trial in 43,000 people. But it presents logistical challenges for a widescale and rapid rollout, as it requires storage at –70°C. The lesser demands of other vaccines—including a candidate developed by the University of Oxford and AstraZeneca—mean they will likely still play an important role in providing vaccinations for the whole U.K. population—and for global coverage, according to Michael Head, a global health researcher at the University of Southampton, “but, for now, this is wonderful news to wake up to.”

*Correction, 2 December, 12:20 p.m.: A previous version of this story said only China and Russia have issued EUAs for COVID-19 vaccines. A few other countries have done so as well.
