About the Study


Coronaviruses are a large family of viruses that cause illness ranging from the common cold to more severe diseases, such as Middle East respiratory syndrome (MERS) and severe acute respiratory syndrome (SARS). Coronaviruses are zoonotic, meaning they are transmitted between animals and people.

An outbreak of the coronavirus disease (COVID-19) caused by the 2019 novel coronavirus SARS-CoV-2 began in Wuhan, Hubei Province, China in December 2019 and has spread throughout China and to over 215 other countries, territories, and areas, including the United States.

Vaccines serve to prepare your immune system for fighting illnesses. Certain cells of the immune system produce antibodies (special proteins) that recognize viruses and other pathogens (things that cause disease) and prevent them from causing illness. Currently, there are several vaccines that have been authorized or approved for the prevention of COVID-19 disease. However, as new strains of the virus emerge globally, there is a need for the development of new and improved vaccines.

Frequently asked questions

View all FAQs

What is a screening visit?

A screening visit is your first visit to our facility and takes roughly 2-4 hours. After filling out paperwork and reviewing a consent form, one of our nurses will go over the details to ensure your understanding.
This is the perfect time to ask any questions about the study and how your participation will affect you.
The nurse will then go over your medical history and take vitals.
The next step is completing a physical with our doctor. If our doctor deems you healthy enough for the study, you will then see our phlebotomist for a blood draw.

How do I prepare for my screening visit?

The night before:

  • Hydrate, hydrate, hydrate!
  • Avoid a large consumption of alcohol
  • Avoid sugary foods and drinks

The morning of:

  • Continue to hydrate well
  • Eat a light, healthy breakfast (Examples: bagels, scrambled eggs, yogurt, fruit, whole grain cereal)
  • Bring a photo ID
  • Make sure you have a form of entertainment (Examples: Books, magazines, mobile video game systems, laptops, etc.)

What questions should I ask the nurse?

First, you can ask our nurses any questions that come to your mind at any point of the process. But some good examples are:

  • Has this new medication/vaccine been tested on humans before?
  • What is the purpose of this new medication/vaccination?
  • What are the risks involved?
  • What company developed the medication/vaccine?
  • What is the procedure?
  • How/What samples are collected?
  • How long is the trial?

What is informed consent?

Informed consent is the process of our volunteers being given all the information about the study. For your protection, all clinical trial facilities MUST give you all the details (including risks and benefits) pertaining to the study before you give consent to volunteer. All volunteers must sign the informed consent before they can participate in a trial. As the study progresses, there could be additional informed consent forms that require your signature.

JCCT takes this process very seriously. You will be given 1 on 1 time with one of our nurses to go over the consent form and ask as many questions as you need before you sign.
