The poliovirus vaccine introduced in the late 1950s[edit source | reply | new]

One possible cause of the 1980s explosion in ME/CFS cases might have been the introduction of the polio vaccine in the late 1950s.[citation needed] This is because natural infection from poliovirus (which the vaccine eliminated from the wild) may confer some cross-immunity against other enteroviruses such as coxsackievirus B and echovirus, two viruses linked to ME/CFS. [1] [citation needed]

Prior infection with wild poliovirus likely does provide immunological cross-protection against coxsackievirus B, as a study from Estonia[2] details the differences between Estonian children immunised with the live attenuated polio vaccine, versus Finnish children immunised with the inactivated polio vaccine; it was found that the Estonian children given the live vaccine (which is closest to wild poliovirus infection) have a stronger T-cell responses against coxsackievirus B4, which the authors suggest may explain why type 1 diabetes (linked to coxsackievirus B4) is 3 times lower in Estonia compared to its neighbour Finland.[citation needed]
