How many days apart is it better to be vaccinated?

The human immune system responds within a certain period of time to an antigen contained in the externally administered vaccine. This antigen may be the spike protein of the virus, the killed virus itself, or genetically engineered genetic sequences (m-RNA). It synthesizes virus particles. The immune system is an invisible system. It needs 14-21 days to synthesize its own protective proteins (our antibodies). During this time, even if we are not aware of it, the cells and tissues of the immune system work very intensely against this new antigenic stimulus.

First, a larger and uneconomical antibody called immunoglobulin M is synthesized. This is a structure similar to the ready power in the military. It is not an economic molecule. Its storage time in the body is limited. Our immune system raises the immunoglobulin G antibodies, which it can store longer and more economically, to a sufficient level in a period of 14-21 days. The synthesis stages of this molecule in cells and tissues are made ready. Thus, the antibody response is provided. The time may be very short at the next real microbe contact.


Our protection occurs within 14-21 days after the first vaccination. In order to increase the effect and duration of this protection, a second vaccine is made so that the response of our immune tissues and cells to their memories is much stronger. For example, our hepatitis-B vaccines (another vaccine prepared by gene engineering technique) administered in childhood in our country are administered three times (in the first month, after one-two months and after 6-12 months) and give lifelong immunity after three applications.

With the application made since the beginning of the 2000s, the hepatitis-B problem in our country has been considerably reduced. The aim of COVID-19 vaccines is to reach an effective level of antibodies as soon as possible. It is necessary that the immunity formed should remain at a protective level for a while. In this respect, 28 days is envisaged as an appropriate logical and scientific period. It is also possible that there will be some changes in this period according to the response of the large population to the vaccine.

Does the coronavirus vaccine cause allergies?

In allergic bodies, every antigen carries the possibility of allergy. For this reason, vaccinations will be made in health institutions, the patient will be kept waiting for 30 minutes in case of early allergy and observed for allergies.

Does the coronavirus vaccine cause infertility?

This type of side effect has not been reported in any vaccine so far.

What are the coronavirus vaccine protection rates?

Although the protective immunity rates vary according to different studies and the age and immune status of the vaccinated person, they are found to be as high as 75-95%. However, the key question here is “how successful can vaccines be in stopping the epidemic”, and we will be able to see the answer together in 2021.

Can breastfeeding mothers get the coronavirus vaccine?

Pregnant and nursing mothers can be vaccinated at their own discretion. It is recommended not to be used in the first trimester of pregnancy.

Is the coronavirus vaccine administered to diabetes and cancer patients?

It can be done provided that it is evaluated by its own clinicians.

As a final word, there is a great social benefit in not listening to those who endanger the future of our people with various conspiracy theories and absurd information, although they are not experts on the internet or in the visual media. Do not forget that the prolongation of human lifespan and the incredible increase in the world’s population in the last 2 centuries have been realized by two great inventions. These are immunization (vaccination) and antibiotics. In this context, the help of every enlightened individual is necessary for the widespread success of vaccination.
