Tetanus Vaccine
(Following Excerpt from Centers for Disease
Control and Prevention for page " MMWR
August 08, 1991 / 40(RR10);1-28 ")
Tetanus in the United States is primarily a disease of older adults. Of 99
tetanus patients with complete information reported to CDC during 1987 and
1988, 68% were greater than or equal to 50 years of age, while only six were
less than 20 years of age. No cases of neonatal tetanus were reported. Overall,
the case-fatality rate was 21% (8). The age distribution of recent cases and
the results of serosurveys indicate that many U.S. adults are not protected
against tetanus. Serosurveys undertaken since 1977 indicate that 6%-11% of
adults 18-39 years of age and 49%-66% of those greater than or equal to 60
years of age may lack protective levels of circulating tetanus antitoxin (4-7).
The disease continues to occur almost exclusively among persons who are unvaccinated
or inadequately vaccinated or whose vaccination histories are unknown or uncertain
(8).
