Japanese scientists at Dokkyo and Jichi Medical University have identified factors that inhibit the production of antibodies in people vaccinated with coronavirus. The relevant study was published in the medical journal medRxiv.
As part of the study, experts examined the analyzes of 378 health care workers who had been vaccinated for three months. The experiments focused on the following factors: the age of the vaccinated, medical history, and their harmful habits.
As research has shown, after vaccination, the decisive factor in determining antibodies became the age of those vaccinated and smoking.
The concentration of antibodies in the blood of smoking volunteers was found to be 140-250 units lower than normal.
According to immunologists, smoking cessation can improve the effectiveness of the vaccine.
