Trial Outcomes & Findings for Live Attenuated Japanese Encephalitis (JE) Vaccine Coadministered With Measles Vaccine in Infants 9 Months of Age (NCT NCT00463684)

NCT ID: NCT00463684

Last Updated: 2019-02-08

Results Overview

Blood serum was collected immediately before administration (Day 0), Day 28, six months post-administration, and 1 year later. Serum neutralizing antibodies to the Beijing-1 JE strain were measured by plaque reduction neutralization test (PRNT) where the neutralizing titer was measured as the inverse dilution at which plaque counts were reduced by 50%. Seropositivity was defined as a titer of ≥1:10.

Blood serum was collected immediately before administration (Day 0), Day 28, six months post-administration, and 1 year later. Serum anti-measles immunoglobulin class G (IgG) antibodies were measured by enzyme-linked immunosorbent assay (ELISA) (Serion ELISA classic Measles Virus IgG, Serion GmbH, Würzburg,Germany). For anti-measles IgG, two definitions of seropositivity were used: per manufacturer's instruction (concentration of\>200 mIU/mL, this table) and when including those with "borderline" results (≥150 mIU/mL).

SECONDARY outcome

Timeframe: 1 year

Population: Not all subjects were followed for a full 30 minutes after injection.

Subjects were monitored for immediate AEs and local reactions for 30 minutes after each injection by a study physician. Thereafter, parents recorded axillary temperature, local reactions (redness, swelling, pain, and other local reactions), and systemic symptoms (high-grade fever, anorexia, crying, diarrhea, drowsiness, insomnia, irritability, vomiting, and other systemic symptoms) in a study diary for 7 days afterwards. Study staff called the subjects' parents 2 days after vaccination and monthly through 1 year to inquire about the child's well being and review the diary card. The subject was visited at home on Day 7 to review and collect the reactogenicity diary card. The subject returned to the vaccination clinic on Day 28, 6 months, and 1 year to be examined, have a blood draw, and review any AEs or serious adverse events (SAE) with parents.
