Rare polio death in Minnesota

Minnesota health officials are reporting an unusual death linked to a strain of polio once used in vaccines.

The Minnesota Department of Health said yesterday that a man, whom they did not identify, with symptoms of the paralyzing disease died last month. The officials said that he was infected with a strain of polio used in an oral, live-virus polio vaccine that was discontinued in the U.S. in 2000, suggesting that he caught the infection from someone who had received the live vaccine before it was pulled from the market. Polio vaccines used in the U.S. today are injected and contain only inactivated virus, though live-virus vaccines are still used in some developing countries, according to the Centers for Disease Control and Prevention (CDC).

The health department didn’t release any details about the man, including his age, but said he had a weakened immune system and multiple health problems.
