D. Schatz et al., AGING AND THE IMMUNE-RESPONSE TO TETANUS TOXOID - DIMINISHED FREQUENCY AND LEVEL OF CELLULAR IMMUNE REACTIVITY TO ANTIGENIC-STIMULATION, Clinical and diagnostic laboratory immunology (Print), 5(6), 1998, pp. 894-896
The period of efficacious immune reactivity afforded by tetanus immuni
zation and the need for continuing some forms of tetanus vaccination p
rograms have been the subjects of recent debates. Our studies demonstr
ate that the level of antitetanus immunity based on immunological memo
ry (i.e., cellular immune responsiveness) varies dramatically as a fun
ction of age, with older individuals constituting a population which i
s increasingly susceptible to tetanus infection.
