Health Canada says the flu vaccine batch recently flagged by New Brunswick Public Health is safe.
The federal department told Radio-Canada it has found no cause-and-effect relationship between the vaccine and three cases of adverse neurological reactions in New Brunswick.
New Brunswick, Nova Scotia, Ontario, Manitoba and Saskatchewan had stopped using the batch pending further testing.
Back on November 15, New Brunswick Public Health reported adverse events in three adults who received the vaccine between October 2 and 20. The neurologic symptoms, which included sustained numbness or weakness of the face and/or limbs, occurred within seven days of receiving the vaccine.
The province uses an electronic health record system which made it possible to identify the specific batch of influenza vaccine correlated to the three reports. They then alerted vaccine providers in the province and public health agencies across the country, and the specific vaccine batch was set aside in five provinces.
On Thursday last week, a Health Canada spokesperson told CBC that after testing the batch and other vaccine lots, the department found no irregularities and has no concern about health-care providers continuing to administer it.
