Platelet aggregation induced by ADP was studied in dogs after vaccination with a modified live-virus distemper vaccine. A significant decrease in platelet counts was observed about 1 week after the vaccination. There were no consistent changes in the aggregability of the platelets. In 4 samples the aggregability was significantly increased compared to the prevaccination values. The observed changes will not cause a defective hemostasis in otherwise normal dogs.
