ORAL POLIO VACCINE
April 2nd, 2009 | Posted by admin | Category: General healthNo Comments
Since it is made with modified but still “live” virus, oral polio vaccine (OPV) sometimes actually causes paralytic polio, the very illness it is supposed to prevent. Injectable polio vaccine (IPV), which is made with killed virus, cannot do this. In Morbidity and Mortality Weekly Report (31:22), the U.S. Public Health Service warns that OPV occasionally endangers not only those who are vaccinated with it but also, for a month afterwards, certain persons living in close contact with them. Anyone with deficient immunity is at risk, and this involves, among others, all cancer or leukemia patients, persons treated with radiation, or anyone taking cortisone-like steroid drugs, whether for arthritis, asthma, or any other ailment.
Since, even though rare, polio paralysis can cripple or kill, the Swedish government has now banned OPV. For the same reason, many American physicians prefer EPV, but, surprisingly, OPV continues to be the most widely used vaccine for polio in the U.S.A.
