And many vaccine reactions can be from the adjuvants used, or contaminants present. Viruses other than the one being vaccinated for can be in that vaccine.

It is now believed that AIDS came from contaminated Hep B experimental vaccine from Merck in the late '70's. There are many YouTubes about this. Also the experimental first Polio vaccines were contaminated. I received 3 of these shots in the early 50's in my state where the "experiment" began.

So it is not only mimicry to the virus legitimately labeled on the vaccine, but from antibiotics (neomycin) in some, or chicken egg residues, and actual other viruses that come along for the ride.

This is why vaccines are dangerous today. They are invasive and you and doctors have no control over that at all!

In fact it might help to avoid EGGS for a while and chicken...to see if your symptoms resolve. If a vaccine has sensitized you to chicken and eggs, you'd have allergic reactions all the time...because they are so common in our foods.
