That's not to say we should ignore these issues or think the issue is really resolved.
Brilliant work Therium. Thank you. There is a woman scientist whose name I cannot recall who has written about retro viruses in vaccines and lost her job for it. (Going through brain fog at the moment)
But this is interesting from Professor Joe Cummings (2010)
Lessons from SV40 contaminated vaccines
Simian virus 40 (SV40) is a monkey virus inadvertently administered to human populations in contaminated vaccines produced in SV40-infected monkey cells. Molecular biology and epidemiological studies suggest that SV40 may be contagiously transmitted in humans by horizontal infection, independently of the earlier administration of SV40-contaminated vaccines. In humans, SV40 has been found associated at high prevalence with specific tumour types such as brain and bone tumours, mesotheliomas and lymphomas and with kidney diseases [3]. SV40 was discovered as a contaminant of poliovirus vaccine lots distributed to millions of individuals in the United States between 1955 and 1963; and contaminated vaccine batches were later circulated worldwide. After SV40 was observed to cause animal and human cell transformations in culture, and tumour formations in animals, researchers began to search for SV40 in human cancers [4]. For example, a 2005 study undertaken in Costa-Rica showed that SV40 is significantly associated with cancers of the immune system [5]. US FDA acknowledges that the SV 40 virus (simian virus 40 from monkey kidney cells) was in the early polio vaccines and its risks [6]: “The experience in the early 1960s with SV40 contamination of poliovirus and adenovirus vaccines and the continuing questions regarding whether SV40 could be responsible for some human neoplasms [cancers] underscores the importance of keeping viral vaccines free of adventitious agents. “ (See also
