Results of all safety studies are summarized in Table 2.
In the laboratory safety study, none of the animals developed
local or systemic reactions and no macroscopic abnormalities were
observed at the injection site at necropsy. At 4 hours after vaccination,
the rectal temperature of vaccinated animals was on average
1.1C higher than in the control animals (p < 0.001) but returned to
normal on the day after vaccination.
In the field safety study, treatment resulted in a local reaction
with a maximum diameter of 1 cm in 13% of the vaccinates and
0.3 cm in 4% of the controls. These local reactions were observed
at 4 hours post vaccination only and had disappeared by the next
day. The numbers of piglets with a deviation from the normal
