There is no evidence that peanut oil is an ingredient in vaccinations.
“Using the theory of food oils in the vaccines to explain the sudden nature of epidemic allergy does nothing to forward the conversation. We did not suddenly put food oils, bee venom, latex, dust, pollens, etc. in the vaccines. … There is ample evidence in the medical literature on the role of vaccination, the toxicity of vaccines and aluminum adjuvants in creating atopy that one does not need to speculate. Allergists already know.”

We don’t know for sure whether or not peanut oil is now or ever has been in any vaccine.
“Peanut oil is not referenced in any of the FDA-approved vaccine package inserts for the vaccines currently in the VaxCalc database. … Another reason its not possible to say with confidence that peanut oil is not and never has been in a US licensed vaccine is that some ingredients are trade secrets and kept confidential.”
From The Vaccine Reaction
“On September 19, 1964, an article titled “Peanut Oil Used In A New Vaccine” appeared in The New York Times.1 It was written by Stacey V. Jones. The piece noted that an influenza vaccine, which had just recently been patented by Merck & Co., Inc., carried a key ingredient known as Adjuvant 65, which contained peanut oil. The adjuvant, aimed at slowly releasing antigens to “stimulate the creation of antibodies,” was described as “an emulsion of refined peanut oil in water to which are added an emulsifier and a stabilizer.”1 … In her book The Peanut Allergy Epidemic: What’s Causing It and How to Stop It, Heather Fraser notes that Merck ultimately decided not to “pursue” Adjuvant 65 for use in vaccines licensed for use in the United States.”
PEANUT OIL USED IN A NEW VACCINE; Product Patented for Merck Said to Extend Immunity – September 19, 1964 – The New York Times
Response to influenza vaccine in adjuvant 65-4 – “A comparison was made of the antibody response and subjective reactions to zonally-purified influenza vaccine in aqueous suspension and in peanut oil adjuvant 65-4.”
Comparison of tissue reactions produced by Haemophilus pleuropneumoniae vaccines made with six different adjuvants in swine. – April 1985 – “Tissue damage caused by six different adjuvants incorporated in a Haemophilus pleuropneumoniae vaccine was compared in swine. The adjuvants compared were four mineral oil compounds, one peanut oil compound and aluminum hydroxide. Inoculations were given in the neck, quadriceps and semitendinosus muscles.”
