Description Module

Brief Summary

The goal of the vaccination is to induce humoral (antibody) and intracellular (T lymphocyte) responses. Various data show that intradermal vaccination is more efficient than intramuscular vaccination: the humoral response is statistically better after intradermic vaccination, compared to intramuscular vaccination, even in target populations such as older subjects or immunosuppressed patients

Detailed Description

Realisation of 2 groups of healthy subjects with 2 intradermal injection of 50 µl of tuberculin + 2 intradermal injection of 50 µl of physiological serum. 5 biopsy performed on 2 Tuberculin injection site, 2 physiological serum site and 1 on healthy skin site :

Group A : healthy young subjects(18 to 40 years old) : 18 subjects
Sub-group A1 (biopsy 30 minutes after injection) : 6 subjects
Sub-group A2 (biopsy 4 hours after injection) : 6 subjects
Sub-group A3 (biopsy 72 hours after injection) : 6 subjects
Group B : healthy old subjects(60 to 75 years old) : 18 subjects
Sub-group B1 (biopsy 30 minutes after injection) : 6 subjects
Sub-group B2 (biopsy 4 hours after injection) : 6 subjects
Sub-group B3 (biopsy 72 hours after injection) : 6 subjects

Determination of the best time (30 minutes, 4 hours or 72 hours)for intradermal vaccination caracteristics after group A and B data analysis. From these results, last group of immunosuppressed patients performed:Group C with 6 immunosuppressed patients (18 to 60 years old)
