mRNA Vaccine
mRNA vaccines are a type of vaccine that use a small piece of genetic material called messenger RNA (mRNA) to teach our immune system how to recognize and fight viruses. Unlike traditional vaccines, which often use weakened or inactivated viruses, mRNA vaccines deliver instructions that prompt our cells to produce a harmless piece of the virus (like a spike protein). This trains our immune system to identify and attack the virus if we are exposed to it in the future. mRNA vaccines are quick to develop and have been crucial in combating diseases like COVID-19.

An mRNA vaccine is a type of vaccine that uses messenger RNA (mRNA) to instruct our cells to produce a harmless piece of the virus it protects against, such as the spike protein of the coronavirus. This harmless protein triggers an immune response, teaching our bodies how to recognize and combat the actual virus if we are exposed to it in the future. Unlike traditional vaccines that use weakened or inactivated viruses, mRNA vaccines do not contain live virus and cannot cause the disease. Vaccines like these have been crucial in fighting diseases such as COVID-19.
