FDA shuts down enquiries about DNA contamination in covid vaccines
After months of enquiries, the FDA says it will not provide further comment on DNA contamination

“FDA and WHO guidelines consider the amount of residual DNA in a single dose of traditional vaccine should not exceed 10 ng (one billionth of a gram).
But this limit - used for traditional vaccines - is unlikely to be relevant to the mRNA vaccines whose lipid nanoparticles can penetrate inside cells to deliver the mRNA efficiently.
A recent preprint paper by Speicher et al, analysed batches of the monovalent and bivalent mRNA vaccines in Canada.
The authors found “the presence of billions to hundreds of billions of DNA molecules per dose in these vaccines. Using fluorometry all vaccines exceed the guidelines for residual DNA set by FDA and WHO of 10 ng/dose.”
Speicher et al also reported finding fragments of DNA larger than 200 base pairs (a measure of the length of the DNA) which also exceeds FDA guidelines.”
I really should be catching up on the last thread instead of posting on this one.
So sorry not to offer my condolences to various people here over the illness of family members and loss of dog. Usually I do my catching up via reading my phone when I am out somewhere and am waiting on something or getting a coffee. I don’t like to log in and type on my phone.
By the time I’ve read about something that happened to someone, it is a good three days or more after the post about it.
