BACKGROUND Haemophilus influenzae serotype b (Hib) has yet to be eliminated despite the implementation of routine infant immunization programs. There is no consensus regarding the number of primary vaccine doses and an optimal schedule for the booster dose. We sought to evaluate the effect of a booster dose after receiving the primary series on the long-term disease incidence. METHODS A stoch...

OBJECTIVES To increase booster seat use among low income parents. DESIGN/METHODS A pre-test/post-test design conducted in nine daycare centers with post-test observations four to eight weeks after the intervention. INTERVENTION Parents who participated in an educational training received free seats, educational programs were provided to all daycare staff and children, and signs in parking l...

OBJECTIVE To assess the effectiveness of a national one week media campaign promoting booster seat use. DESIGN Pre-test, post-test design based on nationally representative random digit dialing telephone survey, with control for exposure to campaign. SETTING Canada. SUBJECTS Parents of children aged 4-9 years. INTERVENTIONS During a one week campaign in May 2004, information on booster ...

BACKGROUND Newborns who have received hepatitis B immunization in 1980s are now young adults joining healthcare disciplines. The need for booster, pre- and post-booster checks becomes a practical question. AIMS The aim of this study is to refine the HBV vaccination policy for newly admitted students in the future. METHODS A prospective study on medical and nursing school entrants to evaluat...

One alternative for management of brucellosis in Yellowstone National Park bison (Bison bison) is vaccination of calves and yearlings. Although Brucella abortus strain RB51 vaccination protects bison against experimental challenge, the effect of booster vaccinations was unknown. This study characterized immunologic responses after dart or booster vaccination of bison with Brucella abortus strai...

The World Health Organization recommends a booster dose of a pertussis-containing vaccine for children aged 1-6 years, preferably during the second year of life. This study assessed the immunogenicity and safety of a pentavalent combination vaccine containing diphtheria, tetanus, acellular pertussis, inactivated poliovirus, and conjugated-Hib polysaccharide antigens, [(DTaP-IPV//PRP-T (Pentaxim...

BACKGROUND Antibody levels wane rapidly after Meningococcal serogroup C conjugate (MenCC) vaccination in young children, rendering the need for an adolescent booster dose. It is not clear whether circulating memory B cells are associated with persistence of MenC-specific antibody levels. METHODS Measurement of MenC-specific IgG and IgA memory B cells and levels of serum and salivary MenC-spec...

We present Booster, a new framework developed for verifiying programs handling arrays. Booster integrates new acceleration features with standard verification techniques, like Lazy Abstraction with Interpolants (extended to arrays). The new acceleration features are the key for scaling-up in the verification of programs with arrays, allowing Booster to efficiently generate required quantified s...

Growth rate of heifers is reduced by prostaglandin F2 alpha (PGF) immunization following a primary and booster regimen. The objective was to attenuate the immune response with or without a booster immunization; specifically, the effects of booster interval, dose of PGF-human serum albumin (HSA) conjugate at booster, adjuvant type, or single immunization with one or two adjuvants were examined. ...
