A batch of Moderna’s Covid-19 vaccine has been halted in Japan when a foreign material was discovered in a vial.
According to officials, a pharmacist in Kanagawa Prefecture saw numerous black particles in one bottle of the vaccination.
The batch had previously been distributed to 3,790 persons. The remainder of the batch has been placed on hold.
It comes little over a week after Japan halted the use of about 1.63 million Moderna dosages owing to contamination concerns.
The black particles were discovered by the pharmacist when screening for foreign substances before administering the vaccination.
The tainted vial has been retrieved by the jab’s domestic distributor.
According to local media sources, there has been no indication of any health risks associated with the potentially tainted vaccination thus far.
Takeda Pharmaceutical, which sells and distributes the vaccine in Japan, put three batches on hold only last week after “foreign elements” were discovered in certain doses of a batch of about 560,000 vials.
Rovi, a Spanish pharmaceutical company that bottles the vaccine, stated in a statement that the problem might be caused by a production line in Spain.
It went on to say that it was looking into the matter.
Foreign substance detected in jabs in the southern prefecture of Okinawa, according to Japan’s health minister, was caused by needles being improperly put into vials.
While hosting the Paralympic Games, Japan is seeing an increase in Covid cases.
Its immunization program has been sluggish to take hold, with just about 40% of Japanese people completely vaccinated and approximately 50% having received one dose.
