That's a resounding No. Many people I know, myself included, get sick after having the flu shot. I discussed it with my environmental allergist and he said it is because it creates immunity overload. If, unbeknownst to us, our systems are already fighting something, we all of a sudden have to fight something else (the vaccination) as well and then we get sick. It seems to make some sense to me. Plus, the other ingredients in the vaccinations are questionable and, I think, would create additional immunity overload (MCS) issues.
