    The special cells that attack germs (pathogens) are part of your immune system. These are your immune cells: macrophages, dendritic cells, basophils, eosinophils, monocytes, neutrophils, mast cells, natural killer cells, B cells, helper T cells, killer (cytotoxic) T cells, suppresor T cells, and memory T and B cells.

  • The Canine Nutritionist

    Jenner not only shared his knowledge through published literature, he also shared the vaccine itself, giving samples to other physicians and anyone else who requested it. Use of the cowpox vaccine grew as those who received it from Jenner passed it on to others. In 1800, Dr. John Haygarth was responsible for the introduction of the vaccine in the United States when he sent some of Jenner’s cowpox vaccine to a physics professor at Harvard University. After introducing the vaccination in New England, professor Benjamin Waterhouse convinced Thomas Jefferson to try the vaccination in Virginia. It was this contact between Waterhouse and Jefferson that led to the establishment of the National Vaccine Institute and the implementation of the United States’ first national vaccination program.
