It has been suggested from study of cell cultures in a lab setting (not demonstrated in living tissue within a human) that an mRNA vaccine can produce short segments of DNA by reverse transcription.  At any given time, trillions of viruses are active in a human body and viral DNA is added to the human genome by these viruses.  How much viral DNA is present in the average young adult?  How does this viral DNA affect the functioning of the cell/tissue/system/human?  Is it permanent?

Viral Replication

The virus is acellular and considered non-living outside the host cell. The replication of the virus occurs only inside the living cells. Only a few genes are present in the smallest virus, whereas many genes are present in the largest virus. These genes encode specific viral proteins.
