Any idea why there is such a strict age limit for this vaccine? Reference
WHO currently recommends that rotavirus vaccines should not be initiated for infants aged 15 weeks or older, with all doses being completed by 32 weeks. These age restrictions are driven by concerns about intussusception risk. Natural intussusception rarely occurs before 3 months of age and the incidence increases 10-fold between 3 and 6 months of age.
*Intussusception is a type of bowel blockage.
