Background:
People get Zika virus from infected mosquitos. They usually don t get very sick. But birth defects were reported in babies born to mothers who had Zika infection. In rare cases, people with Zika infection had a nervous system disease that causes severe muscle weakness and can be life threatening. A new vaccine made from DNA in the code for a Zika virus protein could help the body build an immune response against the virus.
Objectives:
To see if a new vaccine against Zika virus disease is safe and causes any side effects. To study specific immune responses to the vaccine.
Eligibility:
Healthy people ages 18-50
Design:
Participants will be screened with:
Medical history
Physical exam
Urine tests
Participants will have 18 visits over 2 years.
Participants will be randomly assigned to 1 of 3 groups. All will get 3 vaccines at 3 separate monthly visits. They will receive the vaccine in the upper arm muscle. Some will get it by needle and syringe, others by a device that uses high pressure to push the vaccine through the skin.
Vaccine visits last 4-6 hours. Participants will get a thermometer to measure their temperature and a ruler to measure any skin changes at the injection site. They will record this data for 7 days after each injection.
Other visits last 1-2 hours. These include:
Evaluation of any health changes or problems
Blood tests: Some samples may be used for future research.
Participants with side effects may have extra visits.
