How does the Covid-19 vaccine work?

Like other vaccines, Covid-19 vaccines aid in the development of immunity to the virus. All vaccines protect the body by creating antibodies that fight future viruses. The Pfizer-BioNTech Covid-19 vaccine and Moderna Covid-19 vaccine both use mRNA to stimulate the production of these antibodies.

Individuals can be infected with Covid-19 shortly before or after vaccination because it usually takes your body a few weeks to produce the protective antibodies.

After vaccination, side effects can occur. However, this usually means that the body is developing immunity.
