Although the approved vaccines for COVID-19 are new, the science they use has been studied and enhanced through decades of research.

Vaccines work with the immune system and allow a strengthened response to the virus if exposure occurs. Both the Pfizer and Moderna vaccines contain synthetic mRNA, which is genetic information used to make the SARS-CoV-2 spike protein. The spike protein is the part of the virus that attaches to human cells. The Johnson & Johnson vaccine uses viral vector technology.
