A widespread misconception is that mRNA or viral vector COVID-19 vaccines can change your DNA. This is scientifically impossible. mRNA vaccines, like those developed for COVID-19, deliver instructions to cells to make a harmless protein, prompting an immune response. These instructions never enter the cell’s nucleus, where your DNA is stored, and are quickly broken down after use. Viral vector vaccines work in a similar way, without integrating into the genome. For more details, visit the CDC’s educational resources.

3. Microchip Myths Debunked

The Vaccine Adverse Event Reporting System (VAERS) serves as an early warning system for possible vaccine side effects, but its reports do not confirm causation. Anyone can submit a VAERS report, and entries are not automatically verified or investigated as evidence of harm. The CDC cautions that VAERS data should be interpreted carefully and in context with thorough scientific review.

9. Vaccines Outperform Natural Immunity

Although recovering from infection can provide some immunity, studies consistently show vaccines offer more reliable and longer-lasting protection. According to Britannica and the CDC, vaccinated individuals have lower rates of severe illness and fewer breakthrough infections compared to those who rely on natural immunity alone. Vaccines train the immune system safely, without the risks associated with disease complications.

10. No Evidence of Fertility Problems from COVID-19 Vaccines
