Abstract |
Pollinex(®) Quattro Grass has been developed for the prevention or relief of allergic symptoms caused by pollen in both adults and children. Reproduction and juvenile animal toxicology studies have been performed. Subcutaneous injection on Day 14 prior to pairing and on Days 6 and 13 of gestation to pregnant rats at 2000SU/0.5 mL elicited no signs of maternal or embryo-foetal toxicity. Mating, fertility, fecundity and pup parameters were all unaffected by treatment. Once-weekly subcutaneous administration at ascending doses of 300, 800, 2000 and 2000SU/0.5 mL followed by a 4 week non-dose period to juvenile rats from 3 weeks of age showed no signs of obvious toxicity. As in a previously performed adult animal toxicology study with the vaccine, not unexpected, but relatively minor, immuno-stimulatory effects were seen in this study along with injection site reaction which can largely be attributed to the presence of tyrosine in the formulation.
