The research of the investigators is focused on the understanding how the immune system functions and responds to intranasal vaccines. Intranasal vaccines do not lead to the same changes in the blood that intramuscular vaccines do. Therefore, the investigators want to look at the function of immune (lymphoid) organs that are near the nose. The closest immune organs are the adenoids and tonsils. Mice do not have tonsils allowing for the investigators to answer these questions. Human lymphoid tissue will allow the investigators to better understand the molecular behavior of these cells in humans. The purpose of this protocol is to administer the FDA approved live attenuated influenza vaccine or no vaccine to patients undergoing adenoidectomy and/or tonsillectomy for obstructive sleep apnea prior to surgery and then collect the tissue (adenoid and/or tonsil tissue) that would normally be discarded from surgery. This will allow for improved understanding of what happens after vaccination.

Serological outcomes will be compared before and after vaccination and between groups.
The comparisons will specifically compare: Mean HAI Ab titers in serum and mucosal secretions
Time frame: From enrollment to 4 weeks after surgery is completed
Hemagglutinin Levels
Mean HA IgG and IgA titers in serum and mucosal secretions
Time frame: From enrollment to 4 weeks after surgery
Neuraminidase Levels
Mean NA IgG and IgA titers in serum and in mucosal secretions
Time frame: From enrollment to 4 weeks after surgery
Influenza Specific Antibodies
Non-neutralizing influenza-specific antibody titers before and after vaccination
Time frame: From enrollment to 4 weeks after surgery
Seroconversion rats
Comparison of serconversion rates
Time frame: From enrollment to 4 weeks post surgery
