OPV

But in rare instances, the weakened OPV viruses can regain their ability to paralyze and start to circulate among susceptible children, sparking new polio outbreaks in areas where vaccination rates are low.

However, due to the soft nature of polymers, achieving OPV devices with both high efficiency and long operation stability has been a long-standing research challenge.

A: At some point, you’re going to want to stop OPV vaccination, but that point is not for a long time.

Cheap and easy to use, Albert Sabin’s OPV is hands down the best vaccine for eliminating polio in poor settings where clean water and sanitation are lacking.

He and others are encouraged by a study published on 27 October in Nature Energy by Jie Min, an OPV expert at Wuhan University, and his colleagues.
