Abstract
INTRODUCTION An effective immune response to vaccination may be related to nutritional status. This study examined the association of plasma mineral levels with hemagglutination inhibition (HI) titers produced in response to influenza vaccine in older adults. METHODS Prior to (Day 0) and 21 (range = 19-28) days after receiving the 2013-14 influenza vaccine, 109 adults ages 51-81 years, provided blood samples. Serum samples were tested for HI activity against the A/H1N1 and A/H3N2 2013-2014 vaccine virus strains. Plasma minerals were collected in zinc-free tubes and assayed by inductively coupled plasma mass spectrometry. HI titers were reported as seroprotection (≥1:40) and seroconversion (≥ 4-fold rise from Day 0 (minimum HI = 1:10) to Day 21). Both HI titers and mineral values were skewed and thus log2 transformed. Magnesium (Mg), phosphorus (P), zinc (Zn), copper (Cu), iron (Fe), potassium (K) and the Cu to Zn ratio were tested. Logistic regression analyses were used to determine the associations between mineral levels and seroconversion and seroprotection of HI titers for each influenza A strain. RESULTS Participants were 61% white, 28% male, 39% diabetic, and 81% overweight/obese with a mean age of 62.6 y. In logistic regression, Day 21 A/H1N1 seroprotection was associated with P and Zn at Day 21(P < 0.05). Seroconversion of A/H1N1 was associated with Day 21 Cu, P, and Mg (P < 0.03). Day 21 A/H3N2 seroprotection and seroconversion were associated with Day 21 P (P < 0.05). CONCLUSIONS Phosphorus was associated with seroprotection and seroconversion to influenza A after vaccination; these associations warrant additional studies with larger, more diverse population groups.

Abstract
The percentage of CD2+, CD4+, CD8+ and HNK-1+ cells in peripheral blood was investigated in persons occupationally exposed to very low doses of ionizing radiation. Investigations were carried out by monoclonal antibodies and flow cytometry. While significant effects of age and smoking habits on the relative number of CD8 cells and CD4/CD8 ratios could be established, no influence of the very low radiation exposure on the profile of lymphocytic T cells in blood was found, except a very slight effect on the relative number of CD2+ cells.
