Insights
Adults need more pertussis (whooping cough) booster shots (Tdap). Strategies like vaccinating at child-focused clinics can increase uptake, but provider recommendations are key to protecting infants.
Area of Science:
- Public Health
- Vaccinology
- Infectious Diseases
Background:
- Pertussis (whooping cough) is a serious respiratory infection, particularly dangerous for young infants.
- Despite high pediatric vaccination rates, pertussis cases are rising due to waning immunity and adult transmission.
- Current recommendations for adult Tdap (tetanus, diphtheria, and acellular pertussis) vaccine coverage are not being met.
Purpose of the Study:
- To examine strategies for improving adult Tdap vaccine uptake.
- To identify barriers to adult Tdap immunization, focusing on provider recommendations.
Main Methods:
- The study reviews current literature on pertussis epidemiology and Tdap vaccine strategies.
- It analyzes factors influencing adult vaccination decisions and healthcare provider roles.
Main Results:
- Non-traditional vaccination sites (e.g., pediatric clinics) and provider recommendations significantly increase adult Tdap uptake.
- Low adult Tdap coverage persists despite recommendations.
- Lack of provider recommendation is a primary obstacle to adult immunization.
Conclusions:
- Improving adult Tdap coverage is crucial to protect vulnerable infants from pertussis.
- Interventions should focus on enhancing provider vaccine recommendations and utilizing accessible vaccination settings.
- Further research is needed to overcome barriers to provider Tdap recommendations.
Abstract:
Pertussis is a vaccine preventable respiratory infection. Young infants are at high risk of developing severe complications from infection. Despite high rates of pediatric vaccine uptake, there continues to be increases in pertussis cases, likely due to waning immunity from childhood vaccine and increased transmission through adults. Currently, pertussis booster vaccine (Tdap) is recommended for unimmunized adults and for women in the third trimester of each pregnancy; yet adult Tdap coverage remains low. Administering Tdap vaccine at non-traditional vaccination clinics and at sites where adults are accessing care for their children are effective in improving adult Tdap uptake. While most are willing to receive vaccine when recommended by their provider, lack of provider recommendation is a major obstacle to immunization. Future studies to understand barriers to provider vaccine recommendations need to be undertaken to develop interventions to improve adult Tdap vaccine uptake and reduce pertussis infection in the susceptible population.
