I was told that the BCG vaccine I received as a child has altered my DNA. Is this credible?

Yes, it is credible that the BCG vaccine can have an effect on human DNA. Studies have shown that the BCG vaccine can affect the expression of genes related to immune cells, which can enhance the body's response to the vaccine and potentially provide protection against infections. However, these changes are temporary and are not harmful. Overall, the BCG vaccine seems to have a beneficial impact on the immune system.
