Polio

Attributable risk of DTP (diphtheria and tetanus toxoids and pertussis vaccine) injection in provoking paralytic poliomyelitis during a large outbreak in Oman. 1992, Sutter, J Infect Dis

In addition to the lack of vaccination, there are several more causes of paralytic poliomyelitis, such as stress, trauma, physical activity, pregnancy, removal of tonsils and injections. In 1988-1989 there was a polio outbreak in Oman (118 cases), despite for coverage of vaccination in 87%, there was no correlation between the number of doses of the vaccine and paralysis, but many more children were infected who received the DTP vaccine for the previous paralysis of 30 days, 25% of the children became ill due to DTP, and among children 5-11 months because of it 35% were ill.
For the first time the paralytic The vaccine-induced lyomyelitis was described in 1909, and then three polio outbreaks were described among patients with congenital syphilis and with tropical syphilis who received injections of various arsenic-based drugs.However, after the beginning of the 40's they began to inoculate against diphtheria , tetanus and whooping cough, scientists drew attention to the connection between injections and polio. Based on these data, the authors note that it is probably not worthwhile to prick other poliomyelitis vaccines simultaneously.
