Insights
Rotavirus vaccination significantly reduces antibiotic prescriptions for acute gastroenteritis in US children. This finding suggests a role for rotavirus vaccines in combating antibiotic resistance.
Area of Science:
- Pediatric infectious diseases
- Vaccinology
- Public health
Background:
- Antibiotic resistance is a growing global health concern.
- Vaccines are a potential strategy to control the spread of antibiotic resistance.
- The impact of rotavirus vaccination on antibiotic use in the United States was previously unknown.
Purpose of the Study:
- To investigate the association between rotavirus vaccination and antibiotic use in children.
- To determine if rotavirus vaccination influences antibiotic prescriptions for acute gastroenteritis (AGE).
- To assess the potential impact of rotavirus vaccination on antibiotic resistance.
Main Methods:
- Retrospective cohort study of US children born 2007-2018 using IBM MarketScan data.
- Comparison of antibiotic prescriptions for AGE between children with and without complete rotavirus vaccination.
- Analysis included antibiotic switching and national prescription estimates.
Main Results:
- Complete rotavirus vaccination was associated with a 20.7% reduction in antibiotic prescriptions for AGE.
- Vaccinated children were less likely to switch antibiotics after an AGE diagnosis.
- An estimated 67,045 antibiotic prescriptions were averted nationally due to rotavirus vaccination.
Conclusions:
- Rotavirus vaccines effectively reduce antibiotic prescribing for acute gastroenteritis in children.
- This reduction in antibiotic use may contribute to mitigating the development of antibiotic resistance.
- Rotavirus vaccination represents a valuable tool in the public health strategy against antibiotic resistance.
Background:
Vaccines may play a role in controlling the spread of antibiotic resistance. However, it is unknown if rotavirus vaccination affects antibiotic use in the United States (US).
Methods:
Using data from the IBM MarketScan Commercial Database, we conducted a retrospective cohort of US children born between 2007 and 2018 who were continuously enrolled for the first 8 months of life (N = 2 136 136). We followed children through 5 years of age and compared children who completed a full rotavirus vaccination series by 8 months of age to children who had not received any doses of rotavirus vaccination. We evaluated antibiotic prescriptions associated with an acute gastroenteritis (AGE) diagnosis and defined the switching of antibiotics as the prescription of a second, different antibiotic within 28 days. Using a stratified Kaplan-Meier approach, we estimated the cumulative incidence for each study group, adjusted for receipt of pneumococcal conjugate vaccine, provider type, and urban/rural status.
Results:
Overall, 0.8% (n = 17 318) of participants received an antibiotic prescription following an AGE diagnosis. The 5-year adjusted relative cumulative incidence of antibiotic prescription following an AGE diagnosis was 0.793 (95% confidence interval [CI], .761-.827) among children with complete rotavirus vaccination compared to children without rotavirus vaccination. Additionally, children with complete vaccination were less likely to switch antibiotics (0.808 [95% CI, .743-.887]). Rotavirus vaccination has averted an estimated 67 045 (95% CI, 53 729-80 664) antibiotic prescriptions nationally among children born between 2007 and 2018.
Conclusions:
These results demonstrate that rotavirus vaccines reduce antibiotic prescribing for AGE, which could help reduce the growth of antibiotic resistance.
