mRNA COVID-19 vaccines are a class of vaccines that utilize messenger RNA technology to teach the immune system to recognize and fight the SARS-CoV-2 virus. They work by delivering synthetic genetic material into human cells, prompting the production of viral spike proteins and stimulating an immune response. These vaccines, such as Pfizer-BioNTech's BNT162b2 and Moderna's mRNA-1273, played a significant role in controlling the COVID-19 pandemic globally.
