There is no evidence that peanut oil is an ingredient in vaccinations.
The Epidemic of Allergy in Children Launched in the Late 1980s and Early 1990s – Heather Fraser
“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.”

Is there peanut oil in vaccines?
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.”
