Insights
Routine infant vaccinations may cause abscesses in premature infants. This case report highlights the need for further research into vaccine dosing for vulnerable infants to prevent adverse events.
Area of Science:
- Pediatrics
- Immunology
- Vaccinology
Background:
- Routine infant vaccinations are crucial for public health.
- Premature infants benefit from vaccinations, but optimal dosing requires further study.
- Intramuscular abscesses are rare but serious complications of vaccination.
Observation:
- Two premature infants developed painful intramuscular abscesses post-vaccination.
- Magnetic resonance imaging confirmed abscess formation.
- No alternative causes for the abscesses were identified.
Findings:
- The cases suggest a potential link between routine infant vaccinations and abscess formation in premature infants.
- Both infants required surgical intervention and antibiotic treatment.
- This is the first reported instance suggesting vaccinations as a cause of abscesses in this population.
Implications:
- Highlights a potential risk associated with routine infant vaccinations in premature infants.
- Underscores the need for more research on vaccine administration and dosing in premature populations.
- May inform future guidelines for vaccinating high-risk infant populations.
Abstract:
Since the introduction of vaccines, the impact of vaccinations has been immeasurable. Under the current immunization guidelines, infants receive the first of their routine infant vaccinations at 2 months of age. While the benefits of routine infant vaccinations in premature infants have been demonstrated, there is relatively little data on the dosing of these vaccines in premature infants. The medical records of two premature infants who developed intramuscular abscesses after receiving their routine infant vaccinations were reviewed. Both patients developed pain in the area of the injection after receiving their vaccinations. Magnetic resonance imaging findings confirmed the formation of an abscess. No other causes of abscess formation were observed. Both patients required surgical intervention and were treated with a course of antibiotics. To our knowledge, this is the first case report to suggest routine vaccinations as a potential cause of abscess formation in premature infants.

Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
