Safety evaluation of a potent tetanus vaccine (250 Lf) in guinea pigs (Cavia procellus).
A subacute toxicity study of a potent tetanus toxoid (250 Lf) was carried out in guinea pigs. The toxoid was injected subcutaneously at the nape of the neck at dose levels of 1.0, 1.5, and 2.0 ml in Groups II, III, and IV, respectively. In the controls (Group I) 2.0 ml of aluminum phosphate suspension was given in each injection. Periodic evaluations of body weight, food/water intake, general observable behavior, hematology, and blood chemistry in toxoid-injected guinea pigs were similar to those in control guinea pigs. Thus, the toxoid did not cause any side effects up to four times the dose proposed for humans.
