In other cases, notably the vaccines made by Pfizer, Sputnik-V and Moderna, HEK-293 was used during the testing phase. [21] [22] PER.C6, a retinal cell line that was isolated from an aborted fetus in 1985 was used by Janssen in development of COVID-19 Vaccine. [23] [24]
David Matthews, a co-author for this study, clarified that MRC-5 was solely used for testing purposes to determine "how the Oxford vaccine behaves when it is inside a genetically normal human cell." [ 6 ] The manufacturing of the vaccine used the HEK 293 fetal cell line, the kidney cells of an aborted or spontaneously miscarried female fetus ...
Retrovirus can be single-stranded RNA (just as many SARS-CoV-2 vaccines are single-stranded RNA) which enters the cell nucleus and uses reverse transcriptase to make DNA from the RNA in the cell nucleus. A retrovirus has mechanisms to be imported into the nucleus, but other mRNA (such as the vaccine) lack these mechanisms.
In a sharply worded dissent Thursday, Justice Clarence Thomas expressed support for the plaintiffs’ debunked claims that all Covid vaccines are made with cells from “aborted children.”
Two pioneering scientists who created the technology behind life-saving Covid-19 vaccines have won the Nobel Prize in medicine or physiology.
VATICAN CITY (Reuters) -The Vatican told Roman Catholics on Monday that it was morally acceptable to use COVID-19 vaccines even if their production employed cell lines drawn from tissues of ...
The cells were obtained from a single, aborted or miscarried fetus, the precise origin of which is unclear. [3] [2] The cells were cultured by van der Eb; the transfection with adenoviral DNA was performed by Frank Graham, a post-doc in van der Eb's lab. They were published in 1977 after Graham left Leiden for McMaster University. [4]
These messenger RNA vaccines are made using a small section of genetic material from the virus. The genetic blueprint is designed to teach the body how to make a protein used to build immunity.
