I recently read a bit about the mRNA-vaccines for COVID-2019. I fully understand that mRNA cannot enter the genome of a healthy person as they lack the required reverse transcriptase required to transcribe RNA back into DNA. This made one question pop up in my head, though:
What about the people who do have reverse transcriptase in their body? As far as I understand it, a retrovirus like HIV does express the required proteins to form reverse transcriptase as it's part of the virus strategy to integrate itself into the human genome.
Wouldn't that mean that an HIV-positive person, upon being vaccinated using an mRNA-vaccine, could theoretically end up having the RNA-Sequence of the vaccine transcribed into their genome if reverse transcriptase is present in their cells at the right moment? Or am I missing something? Would that mean that the COVID-vaccine could essentially become the artificial equivalent of an endogenous retrovirus, even possibly immunizing future generations?
