About the Study

The purpose of this study is to collect blood (serum) or plasma from healthy people who have not been exposed to N. meningitides bacteria and do not have antibodies to the bacteria. Plasma and serum are the liquid parts of blood (that is, blood without the cells in it). The main difference between plasma and serum is that plasma has proteins that help blood clot, and serum does not. An antibody is a substance made by the immune system to fight infection. Both serum and plasma contain important components called complement proteins. These proteins together with the antibody are important for the immunity against infection-causing bacteria.

This study aims to collect blood (serum) or plasma that has suitable complement from donors for use in laboratory tests to measure antibody responses of subjects participating in studies where vaccines against N. meningitidis are administered. It’s hard to find donors who have human complement that can be used for these tests. Many adults have been exposed to N. meningitidis and already have antibodies in their blood, which prevent them from being eligible to donate plasma or blood (serum) for this study.

Frequently asked questions

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.
