Background:
- The Center for Human Immunology, Autoimmunity, and Inflammatory Diseases is conducting
research investigating how the swine flu (H1N1) vaccine affects the immune system. The
exposure to the new swine flu vaccine gives us a rare opportunity to learn about how the
human immune system responds to a new vaccine.
- Researchers are interested in collecting blood samples from individuals who have
received the vaccine. Participants will be selected from a group of healthy volunteers
who will be receiving the H1N1 vaccine because it is mandatory for their work at the
National Institutes of Health. This protocol will be one of the first studies to
characterize the human innate immune response to H1N1 vaccine.
Objectives:
- To collect blood samples for research purposes before and after participants receive a
standard non-research vaccination against swine flu (H1N1).
Eligibility:
- Healthy individuals 18 years of age and older who are employees of the National
Institutes of Health.
- Individuals who have had confirmed cases of influenza in the past year are not eligible
to participate.
Design:
- Participants will be admitted for a 36-hour inpatient stay, during which blood samples
will be taken frequently. Participants will have a standard intravenous catheter
(similar to the one used for intravenous infusions) put in place to avoid multiple
needle sticks.
- Participants will be assigned into one of two groups; the two groups differ in the
timing of blood draws but not in the overall amount of blood drawn.
- Group 1: Blood samples 30 minutes before and immediately before vaccination. Additional
samples will be taken 2, 4, 6, 8, 10, 12, 14, 16, 18, 24, 30, and 36 hours after
vaccination.
- Group 2: Blood samples 30 minutes before and immediately before vaccination. Additional
samples will be taken over the following 36 hours, with exact timing to be determined
based on the findings from group 1.
- All participants will provide blood samples 7 days after being released from the
inpatient stay.
- Because of the amount of blood being drawn for research, participants should not donate
blood or take part in any other protocols that collect blood while participating in this
study.

Seasonal influenza is a major health problem whose impact is typically reduced by
vaccination. The H1N1 (swine flu) influenza virus is an emerging pathogen which has the
potential to cause devastating morbidity and mortality in the coming months. In June 2009,
the World Health Organization declared the H1N1 outbreak to be a global pandemic. At present
there are limited data on the early non-specific (innate) immune responses in adult
recipients of the H1N1 vaccine.
Therefore the Center for Human Immunology, Autoimmunity, and Inflammatory Diseases proposes
this protocol designed to investigate the early innate immune response. Healthy adult
subjects (NIH employees) will be admitted as inpatients to receive the FDA-licensed H1N1
vaccine followed by serial blood draws. These samples will be used to perform comprehensive
and detailed analyses of the innate immune system s response to vaccination. To our
knowledge, this protocol will be the first study to characterize the human innate immune
response to H1N1 vaccine. This information may be useful in designing newer, more effective
vaccines to prevent the spread of H1N1.
The primary objective is to collect blood to be used strictly for laboratory studies designed
to characterize the innate immune response to H1N1 vaccine. Samples will be collected from
healthy adult volunteers (NIH employees) at baseline and serially during the first 36 hours
after vaccination with the H1N1 vaccine.
