> A potential, adverse effect of the OPV is its known ability to recombine to a form that causes neurological infection and paralysis.[27] This genetic reversal of the pathogen to a virulent form takes a considerable time (at least 12 months) and does not affect the person who was originally vaccinated. The vaccine-derived attenuated virus is normally excreted from vaccinated people for a limited period. Thus, in areas with poor sanitation and low vaccination coverage, the spontaneous reversal of the vaccine-derived virus to a virulent form and its spreading in the environment can lead to unvaccinated people becoming infected.
Which boils down to no, you cannot get polio from the polio vaccine but potentially some others could get polio from you for a short period a year later if they’re not vaccinated.
A couple of paragraphs up in the Wikipedia article: "Oral polio vaccine results in vaccine-associated paralytic poliomylelitis in about three per million doses". I've also seen one in two million doses quoted elsewhere, but it's somewhere around the one in a million mark. You coupld probably quibble about whether that really counts as getting polio, but it's paralysis caused by infection with poliovirus and there is "no clinical difference between the paralysis caused by wild poliovirus, OPV, or VDPV" according to the CDC's FAQ on the topic so that's not a particularly interesting semantic quibble to me.
