Based on projections, Pfizer and BioNTech said they plan to deliver up to 50 million doses of vaccine globally in 2020 and up to 1.3 billion doses in 2021.

“More than 90% effective”

The “vaccine efficacy rate of more than 90%” was measured by comparing the number of participants infected with the new coronavirus in the group that received the vaccine and in the group receiving placebo, explain Pfizer and BioNtech in their press release.

In much of the world, Covid-19 infection rates are reaching record levels, hospital intensive care units are filling up and the death toll continues to rise.

Other ongoing clinical trials

According to the World Health Organization (WHO), 10 clinical trials of vaccines are currently in phase 3 worldwide, including those of the American biotech Moderna, several Chinese state laboratories and the British AstraZeneca, in collaboration with the university from Oxford. Pfizer and BioNTech are the first to release interim results from these trials.

No vaccine has yet received approval for large-scale commercial distribution. But Chinese authorities have given the green light for emergency use for some of these vaccines.

In Russia, much of the political elite have said they have been vaccinated with the Sputnik V vaccine, which the government hopes to deploy massively in the coming months. The country submitted to the WHO at the end of October a request for prequalification of this vaccine, “registered” by the authorities in early August, which in Russia corresponds to the stage prior to the final phase of clinical trials. A second Russian vaccine was registered in mid-October.
