"Some mild problems in the category of older people over 70 do exist, with men who have developed a slightly weaker humoral response when it comes to Sinopharm vaccines. To a lesser extent, it also happens with other types of vaccines. We will pay special attention to this category of people." stated Dr. Marija Gnjatovic from the Institute of Nuclear Medicine.

There are no side effects of the vaccine, Dr. Nikolay Branzalov, Vice-President of Bulgarian Medical Association (BMA) told Nova TV. He himself got vaccinated and said he did not feel pain.

There is an option for the new coronavirus to stay longer in the body and the person could develop symptoms again.

According to the pulmonologist Dr. Alexander Simidchiev "The fact that a person is ill again does not mean that he has become infected again. This is a person who has been ill, the symptoms have subsided and they have returned,"
