Influenza vaccine concurrently administered with a combination measles, mumps, and rubella vaccine to young children.

Children aged 11 to <24 months received 2 intranasal doses of live attenuated influenza vaccine (LAIV) or placebo, 35+/-7 days apart. Dose 1 was administered concomitantly with a combined measles, mumps, and rubella vaccine (Priorix). Seroresponses to measles and mumps were similar between groups.

Hospital-based epidemiologic survey of malignancies in children infected with human immunodeficiency virus in Thailand.

To determine the incidence and spectrum of malignancies in human immunodeficiency virus-infected children, we surveyed 48 hospitals in Thailand between 1996 and 2000. There were 23 children (14 boys and 9 girls; average age at diagnosis of malignancy, 4.2 years), and the incidence rate was 0.

Immunogenicity and safety of two doses of a paediatric hepatitis A vaccine in thai children: comparison of three vaccination schedules.

As fewer children in Thailand are exposed to hepatitis A virus (HAV) and so do not have seroprotective anti-HAV antibodies, they are becoming an important source of HAV transmission. A flexible HAV vaccination schedule would facilitate incorporation of the vaccine into existing immunization programmes, and we compared the immunogenicity and safety of three HAV immunization schedules. An open, randomized, clinical trial was carried out in which healthy children were given a primary dose of the inactivated hepatitis A vaccine, Avaxim 80 paediatric, with a booster dose 6, 12 or 18 months later.

Protective efficacy of hepatitis B vaccine without HBIG in infants of HBeAg-positive carrier mothers in Thailand.

The primary objective of this study was to estimate the efficacy of a recombinant hepatitis B vaccine (H-B-VAXII) in preventing chronic hepatitis B infection when given alone without concomitant hepatitis B immune globulin (HBIG) to healthy Thai infants born of HBeAg-positive carrier mothers. The infants received a 0.5 ml (5 micro g HBsAg) intramuscular injection of H-B-VAXII either at birth, 1, and 6 months of age (Schedule A) or at birth, 1, 2, and 12 months of age (Schedule B).

Primary infection of human herpesvirus 6 in children with vertical infection of human immunodeficiency virus type 1.

The role of human herpesvirus 6 (HHV-6) infection in 227 children born to human immunodeficiency virus (HIV)-seropositive mothers was investigated. Of 41 HIV-uninfected infants, 3 (7%) were positive for HHV-6 DNA in the first month of life, suggesting possible intrauterine infection. The cumulative infection rates of HHV-6 at 6 and 12 months of age were significantly lower in HIV-infected children (11% and 33%, respectively) than in uninfected children (28% and 78%, respectively; P<.

Human herpesvirus 6 (HHV-6) infection and exanthem subitum in Thailand.

Of 50 patients in Thailand suspected clinically of having exanthem, subitum, 31 (62%) were serodiagnosed as HHV-6 infection. Sixteen strains of HHV-6 from 31 patients (52%) whose antibody titers had converted during convalescence were isolated during the acute phase. The disease occurred in infants from 3 months to 1 year of age and most frequently at age 4-6 months.
