Insights
The new pertussis vaccine for adolescents and adults shows high efficacy (92%) and safety. Vaccinating these groups can significantly reduce pertussis cases and protect vulnerable infants.
Area of Science:
- Immunology
- Vaccinology
- Public Health
Background:
- Pertussis remains a concern, particularly for infants, despite existing vaccines.
- Adults are the primary reservoir and transmission source of Bordetella pertussis.
- Current vaccination strategies need enhancement to protect all age groups.
Purpose of the Study:
- To evaluate the efficacy and safety of new pertussis vaccines for adolescents and adults.
- To assess the potential impact of universal vaccination in these age groups on disease incidence and transmission.
- To reduce severe complications in infants caused by Bordetella pertussis.
Main Methods:
- Clinical trials assessing immunogenicity, safety, and efficacy of new pertussis vaccines.
- Modeling disease transmission dynamics in populations with and without universal adolescent/adult vaccination.
- Analysis of pertussis case data in relation to vaccination programs.
Main Results:
- New pertussis vaccines demonstrate good immunogenicity, safety, and 92% efficacy.
- Vaccination of adolescents and adults significantly decreases pertussis incidence in these groups.
- Reduced transmission from vaccinated adults to infants is a key outcome.
Conclusions:
- The new pertussis vaccines are safe and effective for adolescents and adults.
- Universal vaccination programs including these age groups are crucial for controlling pertussis.
- Widespread vaccination will protect infants from severe pertussis complications by reducing transmission.
Abstract:
After the introduction of the pertussis vaccine the number of cases decreased substantially, albeit, the disease remains present affecting mostly young infants in whom it causes severe complications, adolescents and adults. Adults are the main reservoir of Bordetella pertussis and serve as vehicle of transmission reservoir to infants. The new pertussis vaccines, manufactured for adolescents and adults, have good immunogenicity, safety and efficacy (92%) profile. The introduction of this vaccine into a universal vaccination program for adolescents and adults, would decrease the incidence of the disease in this population and more importantly, transmission of the microorganism to infants.

The nurse must practice strict medical asepsis and adhere to infection control guidelines to minimize healthcare-associated infections.
Enhance airway patency
Position the patient correctly to facilitate drainage of the affected lung segments. Manual or mechanical percussion and vibration can also be employed.
