Since mid December 2020, Pfizer vaccine has been authorized for emergency use in the United States for people aged 16 and over.

In May this year, the authorization was extended to people aged 12 and over. At present, among more than 170 million people who have been fully vaccinated with the new crown vaccine in the United States, more than 92 million people have been vaccinated with Pfizer vaccine.

Previously, the United States urgently authorized Pfizer, Modena and Johnson & Johnson three new crown vaccines. Some health experts in the United States expressed the hope that the full authorization of Pfizer vaccine can further enhance people's confidence in the vaccine and increase the number of vaccinated people.

Pfizer's vaccine is jointly developed with German BNT company. It is one of the only two approved mRNA vaccines in the world, with a protection rate of more than 94%. However, in front of the delta mutant strain, more and more people are also breakthrough infected.
