Efficacy against severe rotavirus gastroenteritis through one rotavirus season was 95. In the time period following the 31 days post vaccination, there were nine cases of intussusception in the placebo group and three in the vaccine group. In July 2014, the Rotavirus Organization of Technical Allies Council convened a meeting of research and advocacy organizations, public health experts, funders, and vaccine manufacturers to discuss post-marketing intussusception surveillance and rotavirus vaccine impact data. Furthermore, well-designed post-licensure evaluations should be conducted in regionally representative countries that are also conducting impact evaluations of rotavirus vaccination. Scores range from 0 to 20, where higher scores indicate greater severity. The authors concluded that the number of cases of intussusception with the first dose of RotaShield defined as within 21 days increases with age.

The initial symptoms include recurrent, colicky abdominal pain that occurs every 15 to 20 minutes, often with vomiting and followed by a period of well-being. Further research is also needed to increase understanding of the pathogenesis and etiology of intussusception. Live rotavirus shedding was evaluated in 2 studies among a subset of infants at day 7 after dose 1. Consultation with an immunologist or infectious diseases specialist is advised. Practitioners should consider the potential risks and benefits of administering rotavirus vaccine to infants with known or suspected altered immunocompetence, including those whose mothers received immunosuppressive biologics such as infliximab during pregnancy.
