Vaccination is a powerful means of protection against infectious diseases. As a result of vaccination, a person develops diphtheria, tetanus, pertussis, measles, polio, etc. protects against diseases.

Professor of the Department of Internal Medicine, Research Institute of Cardiology and Internal Medicine, Ph.D. According to Saule Kassenova, in response to the introduction of infectious pathogens into the human body, our immune system, in combination with antigens of pathogenic microorganisms, produces protective antibodies, reducing or eliminating its action.

The COVID-19 vaccine contains pathogenic microorganisms or only the smallest parts of a weak and safe microorganism – antigens. Modern vaccines are characterized by the absence of antigens and the program of their production. When they are introduced, the human body begins to produce specific antibodies that bind antigens and counteract its harmful effects. Mass vaccination protects not only those who have been vaccinated, but also those who have not been vaccinated due to a number of contraindications.

Many of the vaccines against COVID-19 that have been approved for use include the Gam-KOVID-Vac vaccine, called Sputnik V. This vaccine is registered in the Russian Federation. Candidates for the vaccine include the Kazakh vaccine Qaz Covid-in, developed by the Research Institute of Biosafety of the Ministry of Education and Science of the Republic of Kazakhstan.

The Committee for Sanitary and Epidemiological Control of the Ministry of Health of the Republic of Kazakhstan has developed an algorithm for the organization and conduct of vaccination against COVID-19, according to which vaccination is carried out gradually, taking into account the epidemiological significance of different groups. The priority group for vaccination includes infectious diseases hospitals, emergency care, intensive care units, primary health care, etc. medical staff of organizations.

Before vaccination, the vaccinated person is informed about the vaccine, its possible side effects, and a voluntary informed consent or refusal to vaccinate is issued. Previous clinical experience has shown that people with diabetes, hypertension and obesity are at risk of developing severe COVID-19. It is recommended that this group of patients consult a physician to address the possibility of vaccination against COVID-19.

Vaccination against COVID-19 should be delayed if the level of antibodies to the SARS CoV-2 coronavirus G immunoglobulin class is high, because the infected person can better protect himself. Vaccination should also be postponed if you are currently infected with COVID-19. Due to the very rare possibility of re-infection due to COVID-19, vaccination should be postponed for 90 days after infection.

In the event of an allergic reaction to any medication, other vaccines, or food in the past, this should be discussed with your doctor. Side effects of general or local nature may sometimes occur after vaccination. Common side effects include fever of 37-38 ° C, chills, fatigue, and headache. Local – occurs at the site of vaccination, it is slightly swollen and painful.

Thus, vaccination is not the only means of protection against infectious diseases. Such methods of preventing coronavirus infection, such as frequent hand washing with soap or alcohol, wearing a mask in a crowded place, and keeping a distance of at least 1 m when talking, should also be kept in mind.

Saule Laikyzy said that it would be better to consult a doctor about the state of health to make a decision on the possibility of vaccination.
