The randomized, placebo-controlled trials will enrol approximately 30,000 people over the age of 18, with emphasis on people aged 65 and above.

According to NIH, all volunteers would be needed to give informed consent prior to their participation. For the trials, two-third of the participants would randomly receive the vaccine and one third would receive a saline placebo. Randomization will be in a 2:1 ratio with two volunteers receiving the investigational vaccine for each one who receives a placebo. Throughout the duration of trials, neither the investigators no the participants would know if they’ve received the vaccine or the placebo.
