does JR understand any of the terminology
like oncogenes or epigenetics?
Okay, if we are asking rhetorical questions --
Do you understand that every other expert, textbook and public health agency disagrees with this person? That every biologist from the 1960s on has said that RNA cannot affect the nucleus (except a retrovirus, which this is not)? Do you understand that public health experts and virologists know what they are doing, and they have good reasons for believing the vaccine is not dangerous? If you doubt they know what they are doing, you need to look at what they have accomplished. In many countries, these agencies have succeeded in limiting COVID deaths to a level they cannot even be measured in excess deaths. Results count.
Just because you have found one expert who disagrees with the establishment, and you happen to know some of terminology this person uses, that does not prove that 99.9999% of other experts are wrong, and all textbooks are wrong.
