Then, on November 21, 1976, a “Minnesota physician reported to his local health authorities a patient who had contracted an ascending paralysis, called Guillain-Barré syndrome, following swine flu immunization. The physician said he had just learned of this possible side-effect from a cassette-tape discussion of flu vaccination prepared for the continuing education of family practitioners by a California specialist. The Minnesota immunization program officer, Denton R. Peterson, dutifully called CDC and spoke to one of the surveillance physicians there. The latter expressed no interest in the single case, but Peterson was sufficiently bothered to conduct a literature search and did indeed discover previous case reports. “We felt we were sitting on a bomb,” he told investigators. Within a week three more cases, one fatal were reported to Peterson. Two came from a single neurologist who remarked that he had observed this complication of flu vaccine during his residency training. More anxious than ever, Peterson again called the CDC, where the surveillance center was just being told by phone of three more cases in Alabama. The next day they learned of an additional case in New Jersey. By then the CDC was taking the problem seriously.” (** pp. 24-25) Still, Sender was not impressed.
The federal government abruptly suspended the NIIP pending analysis of Guillain-Barré cases emerging in the vaccinated population. Eventually, 532 cases of vaccine-related Guillain-Barré syndrome and at least 25 deaths occurred. One CDC official recalled that he had expected side effects upon the nervous system of some vaccinees, but he had no notion on what scale. No one expected a high frequency and no one then explored the policy implications, particularly in the absence of pandemic, which indeed turned out to be exactly the case. CDC research showed that the actual risk for Guillain-Barré was only about 1 in 1,000 among people who had received the vaccine, which was about seven times higher than for people who did not receive the vaccine.***
The vaccine manufacturers had anticipated the potential for serious side effects from the vaccines they manufactured and had insisted on indemnification by the federal government before releasing pandemic vaccine. Harmed vaccinees and their families sued the federal government and eventually received millions of dollars in damages. Sencer was let go as CDC director. Many people faulted him for his dogged pursuit of universal influenza vaccination.
