As more Americans are becoming eligible for the COVID-19 vaccine, scientists address the potential side effects that come with the vaccination.

Immunologists explain how vaccinations work and what effects it may have on your body.

How it Works

According to an article published by the World Health Organization, the vaccine introduces falsified versions of the virus to get the body’s immune system to react.

“When a pathogen does infect the body, our body’s defenses, called the immune system, are triggered and the pathogen is attacked and destroyed or overcome. Vaccines contain weakened or inactive parts of a particular organism (antigen) that triggers an immune response within the body.”

This means that the vaccination a person receives may cause symptoms or side effects similar to the disease it prevents because it wants to trigger the immune system to respond.

The Effectiveness

A phase three study conducted by Moderna showed nearly a 90% effectiveness of the vaccine against COVID-19.

This means that the body was able to build an immune response.

Side Effects

People who receive the COVID-19 vaccine should expect soreness at the injection site.

Some might even feel fatigued for the following couple of days.

After the phase three study by Moderna, more than 2% of participants reported side effects, including headaches and fatigue after receiving the vaccination.

These side effects do not mean the vaccine caused them to develop the COVID-19 virus, but instead, it gives your immune system symptoms to respond to.
