COVID-19 vaccines can alter my DNA.

Both messenger RNA (mRNA) and viral vector COVID-19 vaccines operate by sending instructions (genetic material) to our cells, allowing them to begin constructing defenses against the virus that causes COVID-19. When the body creates an immune response, it discards all vaccination components in the same way that it discards any information that cells no longer require. This is a typical element of the body's functioning.

The genetic material given by mRNA vaccinations never penetrates your cells' nucleus, where your DNA is stored. COVID-19 vaccinations delivered by viral vectors convey genetic material to the cell nucleus, allowing our cells to develop resistance to COVID-19. However, because the vector virus lacks the machinery required to integrate its genetic material into human DNA, it cannot modify people's DNA.
