Pfizer-BioNTech COVID-19 vaccine
Known by scientists and health specialists BNT162b2, this COVID-19 vaccine is based on a two-dose mRNA vaccine developed by Pfizer and BioNTech. Last year, in December, the FDA approved the vaccine for emergency use in people aged 16 years and older.
Pfizer vaccine was actually the first COVID-19 vaccine to be authorized by the FDA.
Now, the Pfizer-BioNTech COVID-19 vaccine has the approval of 82 countries, and we so many doses taken, the side effects soon followed.
The Pfizer-BioNTech COVID-19 vaccine is an mRNA vaccine that works by giving your immune system “instructions” for developing the spike protein which we’ve mentioned earlier. And again, the vaccine does not contain the virus itself!
