This is a study to test a new vaccine (Covax-19) against COVID-19. COVID-19 is a potentially
deadly disease that is caused by a new strain of coronavirus called SARS-CoV-2. To date,
SARS-CoV-2 has infected over 4 million people worldwide resulted in the deaths of over three
hundred thousand people.
