Taiwan Food and Drug Administration found two separate batches of the Seasonal Influenza Vaccines to contain suspicious white and black suspended particles in the vaccines. The batch number with box label R3J721V and syringe label R3J72 is the suspected batch containing impurities. Our clinic did not use this batch of influenza vaccines. Also, the existing stock of influenza vaccines are belonging to a different batch.
It’s safe to continue our influenza vaccination. If we have more information, we shall update you as soon as possible.
