Going to respond to your comment too just in case you don't check replies to the parent: This is wrong. There is no peanut oil in modern vaccines. Even if there were, peanut oil is usually safe because it contains no peanut allergens. Even if it was in small concentrations, it would be used in such small quantities in vaccine doses that it would be diluted past nothing. Even if all of this were true, the proposed effect would have to be proven, and there is zero evidence for this hypothesis. But none of these things are true, and instead we are left only with propaganda.
