What you need to know about revaccination against coronavirus


The decline in the number of coronavirus cases does not mean that the danger is over. Vaccination and revaccination are still relevant and recommended by world medical communities.

What is coronavirus revaccination?

This is the re-introduction of the vaccine into the human body. The composition contains a reduced amount of active substances than during primary vaccination. The main task is to increase the number of antibodies to the virus to the initial values.

Who should be revaccinated

The procedure is mandatory for people working in medicine and service industries. Doctors do not recommend giving it up, so as not to reduce the immunity obtained after the initial administration of the vaccine.

Are there any contraindications

Any person who has no chronic diseases or is not in the acute phase can be revaccinated. It is worth paying attention to the state of health at the time of the procedure: at a minimum, check your temperature and normalize your blood pressure.

Under what conditions is revaccination not carried out?

Revaccination is not carried out for people under 18 years of age, during the period of exacerbation of chronic and infectious diseases, with intolerance to the components of the vaccine. The procedure may be refused if a person’s temperature rose above 40C when the drug was administered, anaphylactic shock or angioedema occurred.

What are the side effects of revaccination?

In the first days, there may be a deterioration in health, headaches, aches, and an increase in body temperature. After a maximum of 3 days, everything passes. Many people note that they tolerated revaccination much easier than vaccination.

How long should the revaccination be performed

The interval between injections of the vaccine is six months.

Do I need to take an antibody test before revaccination?

No. Studies determine only the quantitative indicator of antibodies, while their qualitative component is not taken into account. Even if you have a lot of them, this is not a guarantee of the body’s resistance to coronavirus. Revaccination should be carried out in any case.

How to prepare for the procedure?

Rospotrebnadzor specialists and many doctors recommend avoiding taking antihistamines. On the day of revaccination, you should feel good and have a stable blood pressure. Before starting the procedure, the doctor examines the person and measures the main indicators. Only after that, he makes a decision on the possibility of admission to revaccination.

After revaccination, it is recommended to reduce the number of social contacts, refuse to visit places of mass congestion for 2-3 weeks. This time is quite enough for the development of the body’s immune response.
