mRNA vaccines are a new type of vaccine that use a small piece of genetic material called messenger RNA (mRNA) to teach our cells how to make a protein that triggers an immune response.
Unlike traditional vaccines, which use weakened or inactivated viruses to stimulate an immune response, mRNA vaccines do not contain any live virus and cannot cause the disease they are designed to protect against.
mRNA vaccines have been in development for decades, but the COVID-19 pandemic provided the perfect opportunity to put them to the test.
The Pfizer-BioNTech and Moderna COVID-19 vaccines are both mRNA vaccines and have been shown to be highly effective at preventing COVID-19.
mRNA vaccines are faster and easier to produce than traditional vaccines, which can take months or even years to develop.
Because mRNA vaccines can be produced quickly and easily, they have the potential to revolutionize the way we respond to pandemics and other infectious diseases.
mRNA vaccines are also highly adaptable, which means they can be modified quickly to target new strains of viruses or other pathogens.
Despite their many advantages, mRNA vaccines are still relatively new and there is much we don't know about their long-term safety and effectiveness.
However, early data suggests that mRNA vaccines are safe and well-tolerated, with only mild side effects such as soreness at the injection site, fatigue, and headache.
