At least 25 people have died in South Korea after getting a flu shot seasonal, which has led the authorities of the Asian country to undertake an investigation to clarify whether there is a relationship between the deaths and the drug.

At the moment, the South Korean authorities have refused to suspend the vaccination campaign against the flu, despite the requests they have received in this regard from different sectors, among which is a group of doctors, according to the agency Reuters.

The health authorities, who began an investigation after the first six deaths occurred, have made this decision to continue with the campaign, as they assure that have not found any relationship between the vaccine and the deaths.

In this regard, the Korea Disease Control and Prevention Agency (KDCA) has ensured that the vaccine does not contain any hidden toxins and that at least seven of the nine people investigated had previous pathologies.

“The number of deaths has increased, but our teams see a low chance that the deaths are the result of vaccines, “said the agency’s director, Jeong Eun-kyeong.

Likewise, the authorities have assured that they are investigating the causes of the deaths, but also examine the entire process in detail, in which various government agencies are involved, from production to production.

Among the 25 deceased, at least 22 –including a 17 year old– were part of a campaign to vaccinate adolescents and the elderly for free. Regarding the origin of the drugs, ten received products from SK Bioscience, five from Boryung and GC Pharma, one from Korea Vaccine and four from Sanofi.
