OBJECTIVES To describe the epidemiology of infant pertussis in King County, Washington, and to better understand the implications for tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) vaccination among older children, adolescents, and adults. DESIGN Retrospective analysis of reported pertussis cases among infants younger than 1 year, January 1, 2002, through December 3...

Vaccination considered as one of the most cost-effective health interventions worldwide  through prevention and control of many serious childhood diseases (1). It is estimated  global coverage of  Dose 3 of Diphtheria, Tetanus, and Pertussis (DTP3)among children one year old has been 86% in 2014 (by range from 77% to 96%  in African Region and Western Pacific Region; respectively) (2). Globally...

Malaysian infants would have to receive nine injections during the first few months of life in order to be protected against disease caused by hepatitis B (HBV), diphtheria, tetanus, pertussis and Haemophilus influenzae type b (Hib) if single HBV and Hib vaccines were used. We evaluated a combined DTPw-HBV/Hib vaccine administered at 1.5, 3 and 5 months after a birth dose of hepatitis B vaccine...

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 <...

BackgroundIdentifying risk factors of incomplete immunization among children is crucial to developing relevant policies improve coverage. In this study, we investigated associated with in Indonesia and elucidated differences between urban rural areas.MethodsThe data came from a national-wide survey, the 2017 Demographic Health Surveys. total, 3264 aged 12–23 months were included study. An statu...

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...

BACKGROUND High rates of endemic disease and recurrent epidemics of serogroup A and C meningococcal meningitis continue to occur in sub-Saharan Africa. A meningococcal A + C polysaccharide diphtheria-toxoid-conjugated vaccine may address this issue. METHODS In Niger three doses of a bivalent meningococcal A + C diphtheria-toxoid-conjugated vaccine (MenD), containing 1, 4 or 16 microg of each ...

OBJECTIVE The WHO aims for 90% coverage of the Expanded Program on Immunization (EPI), which in Guinea-Bissau included BCG vaccine at birth, three doses of diphtheria-tetanus-pertussis vaccine (DTP) and oral polio vaccine (OPV) at 6, 10 and 14 weeks and measles vaccine (MV) at 9 months when this study was conducted. The WHO assesses coverage by 12 months of age. The sequence of vaccines may hav...

BACKGROUND Despite recent success towards controlling poliovirus transmission, Nigeria has struggled to achieve uniformly high routine vaccination coverage. A lack of reliable vaccination coverage data at the operational level makes it challenging to target program improvement. To reliably estimate vaccination coverage, we conducted district-level vaccine coverage surveys using a pre-existing i...
