In a breakthrough development, the Israeli company Vaxil BioTherapeutics has formulated a therapeutic cancer vaccine, now in clinical trials at Hadassah University Medical Center in Jerusalem. If all goes well, the vaccine could be available about six years down the road, to administer on a regular basis not only to help treat cancer but in order to keep the disease from recurring.The vaccine is being tested against a type of blood cancer called multiple myeloma. If the substance works as hoped — and it looks like all arrows are pointing that way — its platform technology VaxHit could be applied to 90 percent of all known cancers, including prostate and breast cancer, solid and non-solid tumors.
