Beskrivelse
Inclusion Criteria:
- Reside in Olmsted County, Minnesota (defined by Olmsted County address in medical record within one year prior to last follow-up date as of data abstraction)
- Receive medical care from Mayo Clinic clinical practice
- Signed research authorization for using medical record for research
Exclusion Criteria:
- Diagnosis of an immunodeficiency (primary and secondary)
- Previous or current diagnosis of a Rheumatological disorders (Rheumatoid arthritis, Lupus, Sjögren, and vasculitis), cancer (chronic lymphocytic leukemia, non-Hodgkin lymphoma, and B-cell malignancy), diabetes, active infection (pneumonia, otitis media, HIV, and EBV), other chronic diseases (multiple sclerosis, etc), renal disease such nephritic syndrome, and protein losing enteropathy
- Current or previous use (within the last 6 months) of systemic corticosteroids, and other immunosuppressive agents (cyclosporin, methotrexate, and mycophenolic acid)
- Vaccination of PPSV-23 (receiving childhood pneumococcal vaccination during infancy is eligible for this study)
- Pregnancy
Enrollment will be delayed 2 weeks for those subjects that can be included but have upper respiratory infection or viral illness to allow for natural resolution.

|---|---|

Eksperimentel: Asthmatics
19-20 year old asthmatics who agree to participate in study will have serum collected for analysis.
PPSV23 vaccine [Pneumonococcal Polysaccharide Vaccine 23-valent (PPSV-23)] will be offered per the ACIP/CDC guidelines.
Those who agree to receive the vaccine will have a second draw for serum 4-6 weeks post vaccination for immunization response.
They will also be follow up after 1 year to assess for asthma control and outcomes.
This arm will additionally allow for comparison of asthma outcomes and vaccine response

Aktiv komparator: Non-asthmatics
19-20 year old non-asthmatic smokers who agree to participate in study will have serum collected for analysis.
PPSV23 vaccine [Pneumonococcal Polysaccharide Vaccine 23-valent (PPSV-23)] will be offered per the ACIP/CDC guidelines.
Those who agree to receive the vaccine will have a second draw for serum 4-6 weeks post vaccination for immunization response.
This arm will allow for comparison of vaccine response between asthmatics and non-asthmatics (smokers)

Andet: Asthmatics - Serum Stored
Once the accrual for the experimental arm is met, 19-20 year old asthmatics who wish to participate in study will have serum collected for analysis.
PPSV23 vaccine [Pneumonococcal Polysaccharide Vaccine 23-valent (PPSV-23)] will be offered per the ACIP/CDC guidelines.
This arm will allow for study of baseline vaccine titers to pneumococcus in asthmatics at same time increase the vaccine uptake in the community.

Comparison of PPSV23 vaccine serotype specific antibody response between asthmatic and non-asthmatic smokers
Tidsramme: Vaccine response will be measured at 4 to 6 weeks after administration of vaccine
|
Vaccine response in form of serotype titers to pneumococcal antigens will be measured 4-6 weeks after vaccination and post vaccine titers will be compared with pre-vaccine titers between asthmatics and non-asthmatics (smokers)

Vaccine response will be measured at 4 to 6 weeks after administration of vaccine
