Google will lead you to research in JAMA and other prestigious publications about peanut oil in vaccines.
There is nothing in those studies about "peanut oil in vaccines". As a matter of fact, the entire JAMA article does not even mention vaccines.
And if you are going to cut-and-paste your response, at least have the courtesy of giving a link.
You should be more skeptical of your anti-vaccine sources.
There are two JAMA articles. The second has to do with peanut proteins in breast milk. It doesn’t take a leap to see a connection.
Are you saying peanut oil has never been a component in any vaccines?
