OBJECTIVE To document the duration of protection afforded by Oka/Merck varicella vaccine over a 7-year period. STUDY DESIGN The subjects were healthy children 1 to 12 years of age originally enrolled in clinical studies to evaluate the primary immune response to varicella vaccine 6 weeks after vaccination. Each was monitored for antibody persistence,(More)
Larvae from seven laboratory strains and eight isofemale lines of Drosophila melanogaster differ significantly with regard to their responses to light in a photokinesis assay in which the larvae are tested en masse. Larvae from the CA-2 laboratory stock fail to disperse on assay plates, although observations of individual CA-2 larvae suggest that the larvae(More)
Foraging-stage third-instar larvae from most wild-type (normal) Drosophila melanogaster stocks are generally repelled by light. To identify factors that affect the larval photoresponse, we elucidated the effects of age, temperature, and time on the photoresponse of larvae from a wild-type Canton-S stock. In addition, we analyzed the larvae from the LI2(More)
