acellular pertussis vaccine: iran’s next step to control the disease?

Acellular pertussis vaccine for adolescents.

BACKGROUND The use of whole-cell pertussis vaccine has led to a significant decline in incidence of the disease among children. This change in the epidemiological profile led to an increased number of cases among teenagers and adults, as a result of loss of immunity to the disease or vaccine after approximately 10 years. An increased number of cases was also observed among non-immunized or part...

Has the change to acellular pertussis vaccine improved or worsened pertussis control?

Should acellular pertussis vaccine be recommended to healthcare professionals?

The aim of this study was to describe recent changes in the epidemiology of pertussis and existing policies regarding recommended and mandatory occupational vaccinations for healthcare professionals (HCPs). The authors carried out an extensive review of references on the PubMed and SciELO databases and the official sites of the World Health Organization, Pan American Health Organization, Center...

Estimating the Effectiveness of Tetanus-Diphtheria-Acellular Pertussis Vaccine

TO THE EDITOR—We read with interest Koepke et al’s analysis [1] of Wisconsin Immunization Registry (WIR) and pertussis surveillance databases to determine effectiveness of tetanus-diphtheria-acellular pertussis (Tdap) vaccines. We are familiar with the challenges involved in using such data sources to evaluate the performance of pertussis vaccines, as we have been collaborating since 2008 in a ...

Kinetics of pertussis immune responses to tetanus-diphtheria-acellular pertussis vaccine in health care personnel: implications for outbreak control.

We assessed the kinetics of the humoral immune response to pertussis antigens following vaccination of health care personnel with adult tetanus-diphtheria-acellular pertussis vaccine (Tdap). By 2 weeks after vaccination, 88%-94% of subjects demonstrated a booster response. This brisk response of adults to Tdap supports a role for vaccination in pertussis outbreak control.

Acellular pertussis vaccine efficacy: An updated systematic review and meta –analysis

Background: Recent studies indicate an increased incidence of pertussis disease in recent years. The aim of this study was to evaluate the efficacy of the acellular vaccine for children (as a replacement of current whole cell vaccine in the Expanded Program on Immunization) and for high-risk adults in Iran through updating current best available evidence.   Methods: We performed a syste...
