BACKGROUND: Tdap is recommended for health care personnel (HCP) aged< 65 years
who received tetanus diphtheria or tetanus toxoid immunization (Td/TT)≥ 2 years earlier …

High rates of pertussis disease in adolescents suggest that additional boosting against
pertussis would be beneficial. A combined acellular-pertussis-containing booster vaccine …

In a clinical trial, adolescents who had received a booster dose of reduced dose diphtheria–
tetanus-5-component acellular pertussis vaccine (Adacel®, Tdap) 5 years earlier maintained …

Background. We conducted a 5-year follow-up study on the persistence of pertussis-specific
antibody and cell-mediated immunity after booster immunization of adolescents aged 11–13 …

Booster vaccination with a reduced-antigen-content dTpa, pediatric DTPa or adult Td
vaccine in DTPa-primed children aged 4-6 years was evaluated. Immunogenicity and CMI …

A tricomponent acellular pertussis vaccine containing pertussis toxoid, filamentous
hemagglutinin, and pertactin combined with diphtheria and tetanus toxoids (DTPa) was …

We compared the reactions and immunogenicity of DT acellular pertussis (DTaP) vaccines
containing pertussis toxoid (PT) and filamentous haemagglutinin (FHA)(2-component DTaP) …

Patients with chronic diseases are at increased risk of complications following infection. It
remains, however, unknown to what extend they are protected against vaccine-preventable …

Adult pertussis vaccination is increasingly recommended to control pertussis in the
community. However, there is little data on the duration and kinetics of immunity to pertussis …

Currently, there are 2 tetanus and reduced antigen content diphtheria and acellular
