What Are mRNA Vaccines and How They Work

The rapid development of mRNA vaccines, such as Pfizer-BioNTech and Moderna, is transforming how we prevent infectious diseases. These innovative vaccines offer faster production, adaptability to viral mutations, and a strong safety profile—marking a revolutionary shift from traditional vaccine approaches.

What Are mRNA Vaccines?

What vaccines are mRNA?
mRNA vaccines use messenger RNA to instruct our cells to produce a harmless viral protein, prompting the immune system to generate antibodies. This prepares the body to fight the real virus if exposed.

How Do mRNA Vaccines Prepare the Immune System?

The vaccine delivers genetic instructions to produce a viral protein, such as the spike protein in COVID-19. The immune system responds by producing antibodies and memory cells, training the body to recognize and fight the virus.
