The Claim
Modified mRNA from COVID-19 vaccines can persist in human cardiac muscle and lymph node tissues for up to 30 days following intramuscular injection, as detected by quantitative reverse transcription PCR in postmortem samples, indicating longer tissue retention than previously observed in animal studies.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
The vaccine's genetic material might stick around in your heart and immune tissues for up to a month after the shot, longer than scientists first thought based on animal tests.
See the scientific wording
Modified mRNA from COVID-19 vaccines may persist in human tissues such as cardiac muscle and lymph nodes for up to 30 days after intramuscular injection, based on detection via quantitative reverse transcription PCR in postmortem samples, suggesting longer tissue retention than initially predicted from animal studies.
What the research says
1 studyThe study says the vaccine's genetic material can last up to a month in muscles, including the heart, which matches the claim.
