What are mRNA vaccines, and how do they work?
mRNA vaccines emerged as a key player during the COVID-19 pandemic, with the likes of Pfizer-BioNTech and Moderna at the forefront. However, they aren’t a new concept; this technology has been simmering away in labs for decades. As we look ahead, mRNA vaccines could revolutionise the way we combat a range of diseases.
Key Points
- mRNA vaccines train the immune system to target pathogen proteins by providing genetic instructions for these proteins.
- They contain mRNA but do not carry complete antigens, which means they work by prompting the body to create these antigens itself.
- Only Pfizer-BioNTech and Moderna’s vaccines have received FDA approval as mRNA vaccines thus far.
- The technology behind mRNA vaccines has been in development for over 30 years, allowing for faster production and updates in response to new variants.
- mRNA vaccines do not alter the DNA in human cells and generally exhibit transient side effects like soreness or fatigue.
- Innovative applications of mRNA technology are being explored for diseases like cancer, Celiac disease, and brain disorders.
