Fear, stress, poverty, poor nutrition, chemicals in our environment, emotional trauma, drug addiction, and every medication or vaccine we have taken alter our DNA either directly or indirectly through epigenetics. What I listed doesn't even begin to encompass all the factors that can alter DNA.

These factors change our bodies and brains physically. The vax is just the tip of the iceberg imo.

On a more optimistic note, being aware of this and learning to live in accordance with nature can heal us. Whatever your beliefs are about a higher power.. I know anything can be healed.
