Objective To determine seroprotection and vaccine response rates produced by a diphtheria–tetanus–acellular pertussis–inactivated poliovirus–Haemophilus influenzae type-b conjugate (DTaP–IPV//PRP~T) vaccine containing a polyribosyl-ribitol-phosphate (PRP)– tetanus toxoid conjugate (PentaximTM) and given with a hepatitis B vaccine. Methods In this multicentre open-label trial, 424 infants who re...

Vaccines can cause fever, and fever in young children can lead to febrile seizures; these facts are not new. Febrile seizures are the most common seizure disorder of childhood and occur in ∼5% of all children, usually those younger than 24 months. We know that vaccines, often administered to children in this age group, can trigger febrile seizures. The article by Duffy et al1 in this edition of...

In 1974, the World Health Organization (WHO) established the Expanded Program on Immunization to ensure that all children have access to routinely recommended vaccines. Since then, global coverage with the four core vaccines (Bacille Calmette-Guérin vaccine [for protection against tuberculosis], diphtheria-tetanus-pertussis vaccine [DTP], polio vaccine, and measles vaccine) has increased from <...

Low levels of reporting indigenous status to the Australian Childhood Immunisation Register (ACIR) in the past have resulted in reduced confidence in vaccination coverage data for Aboriginal and Torres Straight Islander children. This study shows that the reporting of indigenous status has improved from 42% of the estimated national cohort of Indigenous children aged 12 to 14 months in 2002 to ...

An understanding of the antibody persistence elicited by a combined tetanus, diphtheria, 5-component acellular pertussis, and inactivated poliovirus vaccine (Tdap-IPV) after adolescent vaccination is important to optimize booster dosing intervals. Our objectives were to compare the safety and immunogenicity of Tdap-IPV coadministered with hepatitis B vaccine (HepB) and sequential administration...

O ver the course of human history, innumerable advances have been made to extend the length and quality of life. It would be difficult to debate the fact that vaccines have saved more lives than any other medical intervention in the past century. Sanitation, especially clean water, may have saved more lives than any other intervention, but sanitation has been mainly in the hands of engineers. P...

OBJECTIVE To evaluate the immunogenicity and safety of a diphtheria and tetanus toxoids, acellular pertussis, hepatitis B, and inactivated poliovirus-containing vaccine (DTaP-HepB-IPV) coadministered with pneumococcal 7-valent conjugate vaccine (PCV-7) and Haemophilus influenzae type b vaccine (Hib), with separate vaccines concurrently, or staggered (delayed) administration of PCV-7. STUDY DE...

BACKGROUND WHO recommended incorporation of Haemophilus influenzae type b (Hib) vaccination into immunization program. Indonesia would adopt Hib as a National Immunization Program in 2013. We aimed at analyzing immunogenicity, safety, and consistency of a new combined DTP-HB-Hib (diphtheria-tetanus-pertussis-Hepatitis B-Haemophilus influenza B) vaccine. METHODS A prospective, randomized, doub...

OBJECTIVE To determine whether Bacille Calmette-Guerin (BCG) vaccination is linked to the risk of acute lower respiratory infection (ALRI) among children <5 years of age. METHODS Data from Macro International Demographic and Health Surveys and United Nations Children's Fund Multiple Indicator Cluster Surveys were used to identify a primary cohort of 58,021 children in 19 countries (2005-2010)...

The prevalence of immunity against diphtheria among Okayama local government staff members involved in diphtheria infection control was measured. Diphtheria booster vaccination was administered to staff members with low antitoxin levels (<0.1 IU/ml) in order to reinforce of immunity. Ninety-one (36.7%) of 248 staff members, 20-69 years of age, had fully protective antitoxin levels (> or =0.1 IU...
