The degree of immunity of some people; They may be weaker than normal due to age, a disease, or the immunosuppressive drugs they use. The immune response (antibody titer) induced by the Covid-19 vaccine in these people is usually less than usual. For this reason, people with weaker immunity need to get the covid-19 extra dose vaccines more often: when the third dose of vaccine is available, they should have a booster dose.
On the other hand, the situation is a little more complicated for the 3rd dose (extra dose) vaccines of people with a relatively healthy immune system. The newly strengthened B and T cells against Covid are already strongly defending against the coming virus. These cells become more mature as time passes after vaccination and become more ready for hostile viruses. Therefore, if the 3rd dose of vaccine is administered early, they will have restarted an already functioning system from scratch.
Therefore, with the limited information we currently have, we can say that there should be at least 6 months between your 2nd dose of vaccine and your 3rd dose of vaccine. 8 months is even better; even 1 year will be the best.
It will also raise the level of antibodies in your blood whenever extra doses of vaccine are given. this will make you more protective of the disease and less contagious to other people. However, since these antibody levels will dissolve over time, it is necessary not to exhaust your right to the extra vaccine dose early. We will need these extra doses of vaccines even more, especially during the winter months when the disease will spread more and our bodies are more vulnerable.
Finally, it is very important that extra-dose vaccines are primarily administered to the elderly and those with weaker immune systems. Young people and those with a stronger immune system should be given extra doses only after the third dose of priority groups has been given.
