Selv om samtidig indgivelse af OPV kan nedsætte immunresponset over for rotavirusvaccine en smule, er der ikke aktuelt tegn på, at klinisk beskyttelse over for alvorlig rotavirus - gastroenteritis skulle blive påvirket.
Although concomitant administration of OPV may slightly reduce the immune response to rotavirus vaccine, there is currently no evidence that clinical protection against severe rotavirus gastroenteritis would be affected.
