Yes, COVID-19 mRNA vaccines can in fact alter the human genome.

In a study from May of 2021, Zhang et al. showed that RNA
from SARS-CoV-2 can be reverse transcribed and integrated into the human genome
within infected cells [1].  The researchers
from MIT and the National Cancer Institute explained that this RNA can then be
expressed as chimeric transcripts and detected inside patient-derived
tissues.  Such integration would allow
for prolonged viral RNA shedding beyond the stage of there being evidence for
virus replication – yielding positive PCR tests outside the time period of
acute infection or symptomatic relief [2] [3]. 
This has been widely reported [4].

The above lines up with the fact that in some patient
tissues, an abundance of …read more
