mRNA vaccines train our bodies to trigger an immune response to the disease, and don't affect or interact with our DNA in any way.

Vaccine development process was informed by decades of research and large-scale clinical trials with thousands of participants.

After two required doses, the Pfizer-BioNTech and Moderna vaccines have a 94% to 95% efficacy rate of protection against COVID-19.

They may include pain at the injection site, tiredness, headache, muscle and joint pain or chills and a slight fever.

Remember, the vaccine does not contain the virus, so it cannot give you COVID-19.
