BNT162b2

BNT162b2 is a COVID-19 vaccine developed by Pfizer and BioNTech. It uses a piece of genetic material called messenger RNA (mRNA) to instruct your cells to produce a harmless part of the virus called the spike protein. This prompts your immune system to recognize and remember the virus, so if you're exposed later, your body can quickly respond and prevent illness. The vaccine does not contain live virus and cannot cause COVID-19. It has been shown to be effective in reducing severe illness and transmission, contributing to pandemic control efforts.
