Cholera Clinical Trial
Official title:
A Phase 1 Randomized, Double-Blind Placebo Controlled Study to Evaluate the Safety and Immunogenicity of the LIve Oral Cholera Vaccine Candidate PXVX0200 Vibrio Cholerae Serotype 01 Inaba CVD 103-HgR Vaccine Strain
The purpose of this study is to compare the safety and immunogenicity of a single dose of the PXVX0200 live cholera vaccine versus placebo in volunteers (Vaccinees) and whether PXVX0200, which is a live attenuated bacteria, can be transmitted to other adults living in the same household.
Approximately 60 subjects and up to 120 household contacts will be enrolled in the United States. Vaccinees will be randomly assigned to receive either PXVX0200 or placebo in a 5:1 ratio and will be followed for 180 days postdose. ;
