Summary

Physicians are more likely to recommend the varicella vaccine when they trust its effectiveness and align with national guidelines. Pediatricians show higher recommendation rates for this important childhood immunization.

Area of Science:

  • Immunization Practices
  • Vaccine Hesitancy Research
  • Pediatric Public Health

Background:

  • Despite varicella vaccine availability since 1995, varicella (chickenpox) immunization rates remain suboptimal.
  • Understanding physician recommendation factors is crucial for improving vaccine uptake.

Purpose of the Study:

  • To identify factors influencing primary care physicians' self-reported likelihood of recommending the varicella vaccine.
  • To assess the relationship between physician beliefs and varicella vaccine recommendation practices.

Main Methods:

  • A 1999 survey of 281 primary care physicians in Minnesota and Pennsylvania who had previously participated in vaccination barrier surveys.
  • Physicians' beliefs regarding varicella disease and vaccine efficacy were assessed.

  • Self-reported likelihood of recommending varicella vaccine for different pediatric age groups was evaluated.

    • Main Results:

    • High recommendation likelihoods were reported for varicella vaccine across pediatric age groups (12-18 months, 4-6 years, 11-12 years).
    • Physician belief in vaccine efficacy significantly correlated with higher recommendation rates; belief in vaccine failure led to lower recommendations.
    • Pediatricians were significantly more likely to recommend the varicella vaccine compared to family physicians and general practitioners.

    Conclusions:

    • Physician recommendation of varicella vaccine is strongly associated with agreement with national immunization recommendations.
    • Belief in the varicella vaccine's efficacy is a key factor driving physician recommendations.
    • Perceived parental desire for the vaccine also influences physician recommendation likelihood, particularly among pediatricians.
