No Association Between Rotavirus Vaccination and Intussusception in New Study

Age-specific incidence rates were main outcome measure. Thank you for your study. We review these safety data for the new vaccines and for Rotashield to provide background information relevant for considering age recommendations for rotavirus vaccination. While there's a way to go yet, I want to assure you will they have my full confidence and gratitude to the finish! What is the Rotavirus Vaccine? The mean observation period was 4. Nearly 62% cases were treated surgically and 33% radiologically.

Length of hospitalization and hospital costs were also analyzed. Ultrasound diagnosis was confirmed by an independent radiologist in 94% of a randomly selected group of intussusception cases at 1 of the 2 hospitals. Some infectious pathogens and underlying diseases might play an important role in the pathophysiology of intussusception. The study estimate relative risk is calculated from the relationship between the risk that an intussusception will occur during the risk period and the risk of intussusception during the control period, using conditional Poisson regression. Patel, Potential Intussusception Risk Versus Health Benefits From Rotavirus Vaccination in Latin America, Clinical Infectious Diseases, Volume 54, Issue 10, 15 May 2012, Pages 1397—1405, Abstract Background. As shown from the experience with these three vaccines, contemporary live attenuated viral vaccines have had a major impact on disease caused by these ubiquitous human pathogens. Of the 753 episodes of intussusception reported in 750 infants, 701 were in vaccinated infants 34.

Intussusception & Rotavirus Vaccine

The initial search produced 196 studies from all 4 databases. Among 133 children hospitalised for varicella, only 16 were vaccinated; samples of vesicle scrapings were collected in 57% for genotyping. Notably, there would be 2,123,800 fewer doses of vaccine given in a strict schedule because the infants would be too old to receive the vaccine. Literature and media reviews were conducted to discover vaccine safety-related events. One of the key findings was a difference in the age distribution of the vaccine-related cases, within a week of the first dose at 2 months old. This review summarizes the available data on the safety of rotavirus vaccines with regards to intussusception. Data from a large-scale, prelicensure safety trial and postlicensure monitoring do not indicate an association between the current RotaTeq vaccine and intussusception.

Association Between Rotavirus Vaccination and Risk of Intussusception Among Neonates and Infants: A Systematic Review and Meta

None of the infants who received the vaccine before the 60th day of life 16% of all doses developed intussusception. While this paper discusses only the vaccine component, the same system could also be eventually used for monitoring drug effectiveness including the use of substandard drugs and drug safety. Here, we describe the principles of viral inactivation and the application of these principles to vaccine development. Although efficacy against hospitalizations was available from clinical trials, efficacy against rotavirus deaths has not been directly evaluated. Although a rhesus rotavirus-based quadrivalent vaccine is highly effective in preventing severe diarrhea in developed countries, in developing countries its efficacy has been less impressive.

We found no epidemiologic evidence for an association between intussusception and natural rotavirus infection, but our study was limited by an insufficient number of cases to definitively exclude a causal link. Wild-type rotaviruses do not appear to have a major role in triggering intussusception. Vaccine list prices and price catalogues were used for cost-assessment. The information will be posted with your response. It has potential to respond quickly during outbreaks and epidemics. To evaluate rates of intussusception hospitalization among infants in Vietnam before the introduction of rotavirus vaccine.

Horizontal transmission of vaccine virus was demonstrated in 15 percent of the vaccine recipients and 13 percent of the placebo recipients with rotavirus-positive diarrhea. Intussusception represents the most common cause of gastrointestinal obstruction in children aged between 3 months and 3 years. Data Sources For this systematic review and meta-analysis, PubMed, Web of Science, Cochrane library, and Embase databases were searched from January 1, 1999, through December 31, 2018, using no language restrictions. Similar findings were observed in the United States after use of RotaShield, prompting a debate about whether restriction of RotaShield to infants younger than 3 mo of age would have averted withdrawal of the vaccine 101112. This study aimed to summarize vaccine safety-related events between 1985 and 2018 in China and analyze profit motives of these events. We used these pooled estimates to calculate the annual number of intussusception cases occurring in these age groups in each country in the absence of a rotavirus vaccination program ie, baseline. During the first 5 years of life an estimated 1 child of 28 is admitted with rotavirus infection 4% of all medical admissions.

Rotavirus Vaccine and Intussusception

Author Contributions: Drs Lu and Ding contributed equally to this study. The corresponding author had full access to all the data in the study and had final responsibility for the decision to submit for publication. Thirty-five confirmed intussusception cases have been reported in patients receiving the vaccine. The use of inputs generated by regional studies conducted under real world conditions, as well as the bounds of our uncertainty analysis, suggests that our conclusions are robust. However, few studies have made postmortem determination of the etiologic cause of diarrheal deaths. Although we found no overall increase in intussusception following receipt of rotavirus vaccine, there was some evidence of an elevated risk following the first dose of both vaccines.

We identified a total of 869 intussusception cases in Ho Chi Minh City during the 3-year study period, for an annual rate of 296 per 100 000 infants. Causes of death were obtained by chart review and verbal autopsy. On the basis of the error estimates and distributions for model inputs, we conducted 2,000 simulations to obtain median estimates of deaths averted and caused as well as the uncertainty ranges, defined as the 5th-95th percentile, to provide an indication of the uncertainty in the estimates. To determine the mean proportion of children hospitalized by age category, we averaged the proportion of children in each age category across studies. . All clinicians involved in the assessment and care of pediatric patients should therefore have a sound understanding of this condition and its management. Please see our for details.
