Member of the Scientific Committee of Coronavirus of the Ministry of Health and Specialist in Infantile Infectious Diseases of Gazi University, Prof. Dr. Hasan Tezer explained why two doses of the Covid-19 vaccine of Chinese origin will be applied 28 days apart. Prof. Dr. Tezer noted that when examining the phase 2 vaccine studies, the two-dose schedule was evaluated. Stating that these schedules are vaccination applications performed at intervals of 0-14 and 0-28 days, Prof. Dr. Tezer said:
“When we look at these diagrams, we see that when the vaccine is administered with an interval of 0 to 28 days, the antibody, that is, the immune response, is higher than that of 0 to 14 days. When we look at our vaccination information, people can protect people with higher immune response and longer immune response due to higher immune response. In Covid-19 infection, we will monitor and evaluate contagion. High level of immune antibodies can also prevent contagion. These are the advantages for us. The vaccine creates an immune response after the first dose, but what we really want is the effect that occurs after the second dose. How long these schemes will protect us, we do not know for the moment. Our objective is to provide long-term protection. We do not know this in other vaccines. The studies that we call Phase 3 study continue. In our country, the studies with da interim coughs announced last week. “

This means that there are studies that show both its safety and the antibody responses to which it is immune in our body. “
