摘要如下:
“Our results indicate a fast up-take of BNT162b2 into human liver cell line Huh7, leading to changes in LINE-1 expression and distribution. We also show that BNT162b2 mRNA is reverse transcribed intracellularly into DNA in as fast as 6 h upon BNT162b2 exposure.”
“In the BNT162b2 toxicity report, no genotoxicity nor carcinogenicity studies have been provided [26]. Our study shows that BNT162b2 can be reverse transcribed to DNA in liver cell line Huh7, and this may give rise to the concern if BNT162b2-derived DNA may be integrated into the host genome and affect the integrity of genomic DNA, which may potentially mediate genotoxic side effects. At this stage, we do not know if DNA reverse transcribed from BNT162b2 is integrated into the cell genome. Further studies are needed to demonstrate the effect of BNT162b2 on genomic integrity, including whole genome sequencing of cells exposed to BNT162b2, as well as tissues from human subjects who received BNT162b2 vaccination.”
我的理解是,該研究發現體外細胞逆轉錄發生的生化指標證據,但還不確信體內逆轉錄是否發生,需要做全基因組測序才能確定。
我的評點:如果最終被基因測序證明逆轉錄,基因毒性就被證明,那麽被改變的基因就可能會被遺傳。。。我因粗通毒理學原理,對MRNA 疫苗的基因毒性 一直有擔心,所有一直強烈反對對小孩打這種疫苗,現在看來大概率我是對的。
