Pfizer-BioNTech Vaccine
The Pfizer-BioNTech vaccine is a COVID-19 shot that helps your immune system recognize and fight the virus. It uses messenger RNA (mRNA) technology, which instructs your cells to produce a harmless piece of the virus called the spike protein. This prompts your immune system to respond and build protection without causing illness. The vaccine is administered in two doses a few weeks apart and has been shown to significantly reduce the risk of severe COVID-19 illness, hospitalization, and death. It is supported by extensive research and has been widely used around the world to help control the pandemic.
