evidence: The big change came with vaccines. Peanut oils were introduced as vaccine excipients in the mid 1960s. An article appeared in the NY Times on 18 Sept, 1964 that would never be printed today. [8] The author described how a newly patented ingredient containing peanut oil was added as an adjuvant to a new flu vaccine, in order to prolong the "immunity." The oil was reported to act as a time release capsule, and theoretically enhanced the vaccine's strength. Same mechanism as with penicillin. [...] Why was peanut allergy so violent? Adjuvant pioneer Maurice Hilleman claimed peanut oil adjuvants had all protein removed by refining. [9] The FDA disagreed. They said some peanut protein traces would always persist [10]- that even the most refined peanut oils still contained some traces of intact peanut proteins. This was the reason doctors were directed to inject vaccines intramuscular rather than intravenous -- a greater chance of absorption of intact proteins, less chance of reaction. [...] So in addition to all the other problems with vaccines delineated in our text, now we have a new one -- peanut oil excipients. Which all by themselves can cause severe, even fatal, episodes of shock, as well as chronic allergy -- irrespective of the mercury, aluminum, formaldehyde, ethylene glycol, and the attenuated pathogens which the manufacturers do admit to.
