Improving community coverage of Japanese encephalitis vaccination: lessons learned from a mass campaign in Battambang Province, Cambodia.

A mass Japanese encephalitis (JE) immunization campaign for children aged 9 months through 12 years was conducted in 2013 in Battambang province, western Cambodia. Vaccinators working at almost 2,000 immunization posts in approximately 800 villages provided vaccinations to almost 310,000 children using one dose of Chengdu Institute of Biological Products' live, attenuated SA14-14-2 JE vaccine (CD-JEV), achieving a coverage rate of greater than 90%. Lessons learned, in general for mass vaccination campaigns and specifically for vaccination with CD-JEV, are described.

An evaluation of adverse events following an immunization campaign with the live, attenuated SA14-14-2 Japanese encephalitis vaccine in Cambodia.

Introduction: Japanese encephalitis (JE) virus is the most common cause of vaccine-preventable encephalitis in Asia. The SA14-14-2 JE vaccine manufactured by Chengdu Institute of Biological Products has been shown to be safe and effective in clinical trials and childhood routine immunization programs. However, there are few published reports describing results of surveillance for adverse events following immunization (AEFI) when the vaccine is used in mass campaigns.

Evaluation of immunization knowledge, practices, and service-delivery in the private sector in Cambodia.

A study of private-sector immunization services was undertaken to assess scope of practice and quality of care and to identify opportunities for the development of models of collaboration between the public and the private health sector. A questionnaire survey was conducted with health providers at 127 private facilities; clinical practices were directly observed; and a policy forum was held for government representatives, private healthcare providers, and international partners. In terms of prevalence of private-sector provision of immunization services, 93% of the private inpatient clinics surveyed provided immunization services.

Transmission dynamics and prospective environmental sampling of adenovirus in a military recruit setting.

Background: High levels of morbidity caused by adenovirus among US military recruits have returned since the loss of adenovirus vaccines in 1999. The transmission dynamics of adenovirus have never been well understood, which complicates prevention efforts.

Methods: Enrollment and end-of-study samples were obtained and active surveillance for febrile respiratory illnesses (FRIs) was performed for 341 recruits and support personnel.

Evaluation of in vivo interactions in mice between flurazepam and two neuroactive steroids.

The development of neuroactive steroids as anticonvulsant medications may be useful both as a primary treatment and as an adjuvant to other anticonvulsants. They may be limited, however, by sedative and ataxic side effects. In the current study, 3 alpha-hydroxy-5 beta-pregnan-20-one and alfaxalone, two prototypic neuroactive steroids, were shown to potentiate the ability of flurazepam to antagonize electrically precipitated tonic hindlimb extension in mice at doses that by themselves had little antiseizure efficacy.
