A polio jab that fell out of favour in the 1960s should be given a frontline role to help stamp out the disease. [s]Dawn[/s] reports that this is according to scientists at the [b]Imperial College London[/b] and the [b]Christian Medical College[/b] in [b]Vellore[/b], in [b]India[/b], who investigated whether the old-fashioned vaccine still had a part to play. ‘Because IPV (injected polio vaccine) is injected into the arm, rather than taken orally, it's been assumed it doesn't provide much protection in the gut and so would be less effective at preventing faecal transmission than oral polio vaccine (OPV),’ said Jacob John of Christian Medical College. ‘However, we found that where the children already had a level of immunity due to OPV, the injected vaccine actually boosted their gut immunity,’ he said.
