Here's what the science says about COVID-19 vaccine myths:
COVID-19 vaccines don't cause you to become sick with COVID-19. The COVID-19 vaccines authorized for use in the U.S. don't contain the live virus that causes COVID-19. Some people may have side effects from the vaccine, such as a fever or muscle pain. But these symptoms usually go away in a few days.
Currently, there is no evidence that any COVID-19 vaccine causes fertility problems. COVID-19 vaccination is recommended for people who are trying to become pregnant or might become pregnant in the future.
COVID-19 vaccines won't track your location or movements. COVID-19 vaccines were developed to help the body build immunity to the virus that causes COVID-19. Also, COVID-19 vaccines don't contain preservatives, antibiotics, metals, or aborted fetal tissues or cells.
COVID-19 vaccines deliver instructions to teach the body how to build protection against the COVID-19 virus. The Pfizer BioNTech and the Moderna COVID-19 vaccines use genetically engineered messenger RNA (mRNA). The mRNA gives cells instructions for making a piece of protein found on the surface of the COVID-19 virus. The protein is then displayed on the surface of cells in the body. Once the immune system recognizes that the protein doesn't belong there, it makes antibodies to fight off what looks like an infection. After the mRNA delivers instructions, it's immediately broken down. It doesn't enter the nucleus of the cells, where the DNA is kept. COVID-19 vaccines don't change your DNA. Also, the genetic material delivered with vector vaccines, such as the Johnson & Johnson/Janssen COVID-19 vaccine, doesn't change or become a part of your DNA.
