  • Effect of 25-hydroxy vitamin D3 levels on immunologic response (antibody responses) to injectable seasonal (2011-2012) trivalent influenza vaccine (Observational component) [ Time Frame: At 4 weeks post-vaccination ]
    Descriptive statistics will be used to assess for differences in the occurrence of self-reported flu-like illnesses in the study population.
  • Effect of cholecalciferol supplementation on immunologic response (antibody response) to injectable seasonal (2012-2013) trivalent influenza vaccine (Intervention component) [ Time Frame: Up to 24 weeks post-vaccination ]
    Descriptive statistics will be used to assess for differences in the occurrence of self-reported flu-like illnesses in the study population. Will be estimated with confidence intervals at each time point. Tested by Wald Chi-square test, and the odds ratio (with confidence intervals) will be reported.
  • Effect of 25-hydroxy vitamin D3 levels on immunologic response (antibody responses) to injectable seasonal (2011-2012) trivalent influenza vaccine (Observational component) [ Time Frame: Baseline (pre-vaccination) and post-vaccination at week 4 ]
  • Effect of cholecalciferol supplementation on immunologic response (antibody response) to injectable seasonal (2012-2013) trivalent influenza vaccine (Intervention component) [ Time Frame: Baseline (pre-vaccination) and post-vaccination at weeks 16, 20, and 24 ]

Cholecalciferol and Flu Vaccine in Treating Healthy Participants
Immune Responses to Influenza Vaccine Among Healthy Employees Working at Roswell Park Cancer Institute and the Relationship to Vitamin D Status
This randomized clinical trial studies cholecalciferol and flu vaccine in treating healthy participants. Cholecalciferol may increase the immunologic response of flu vaccine in healthy participants. Flu vaccine may help the body build an immune response and help prevent flu

PRIMARY OBJECTIVES:

I. To examine the effect of 25-hydroxy vitamin D3 levels on the immunologic response (antibody responses week 4 [4 weeks (+/- 7 days)] post-vaccination) to the injectable seasonal (2011-2012) trivalent influenza vaccine among Roswell Park Cancer Institute (RPCI) employees. (Observational component) II. To examine the effect of vitamin D3 (cholecalciferol) supplementation on the immunologic response (antibody response Week 16 [4 weeks (+/- 7 days)] post-vaccination) to the injectable seasonal (2012-2013) trivalent influenza vaccine among RPCI employees. (Intervention component)

SECONDARY OBJECTIVES:

I. To track occurrences of flu-like illness in the study population from November 1, 2011 through April 1, 2012, using a standardized epidemiologic questionnaire. (Observational component) II. To determine the relationship between 25-hydroxy vitamin D3 levels at time of vaccination and its immunologic responses Week 20 (8 weeks [+/- 7 days]) and Week 24 (12 weeks [+/- 7 days]) following administration of the injected seasonal (2012-2013) trivalent influenza vaccine. (Intervention component) III. To track occurrences of flu-like illnesses in the study population from November 2012 through April 2013, using a standardized epidemiologic questionnaire. (Intervention component) IV. To evaluate the association between single-nucleotide polymorphisms (SNPs) and polymorphisms in the deoxyribonucleic acid (DNA) sequence of vitamin-D3 metabolizing enzymes, measures of vitamin-D3 metabolism (24,25 hydroxy [OH] vitamin D3) and response to seasonal (2012-201) trivalent influenza vaccine. (Intervention component)

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

ARM I: Patients receive low-dose cholecalciferol orally (PO) once daily (QD) for 12 weeks, followed by the seasonal (2012-2013) trivalent influenza vaccine intramuscularly (IM).

ARM II: Patients receive high-dose cholecalciferol PO QD for 12 weeks, followed by the seasonal (2012-2013) trivalent influenza vaccine IM.

After completion of study treatment, patients are followed up periodically.
