Since the beginning of vaccination in Ukraine, a lot of unreliable information has appeared regarding the effect of vaccination against COVID-19. We decided to find answers from an expert. Yuriy Leonov, a geneticist at the department of molecular biological research at the EUROLAB clinic, answered 8 pressing questions about vaccination.
Vaccinated people and those who plan to get vaccinated are concerned about many questions. How vaccination works, whether it is necessary to continue to wear a protective mask, whether it is possible to have only one vaccination, etc. — we have collected all the answers in the material.
1. Can I get COVID-19 after vaccination?
Yes, there is a possibility that a person can get sick after two doses of the vaccine. These are features of the immunity of each individual person. But! In 90% of cases, the disease will be mild or asymptomatic. Vaccines provide 98% protection against severe disease.
2. Will I be contagious to others after being vaccinated against COVID-19?
No. A person does not release the virus after vaccination! It is not contagious!
3. Is it necessary to wear a mask and follow anti-epidemic measures?
Yes, it is worth wearing a mask and following anti-epidemic measures. First, as mentioned earlier, there is a possibility that a person may get sick. She will have an asymptomatic course, but at the same time she can infect others. Secondly, we are now entering the classic epidemic period of SARS-ARS. Vaccination against the coronavirus does not protect against the flu and other colds. Therefore, the mask and anti-epidemic measures will contribute to the fact that we will be better protected from these diseases.
4. What will happen if I do not receive the second dose of the vaccine against COVID-19?
The formed immunity will be much weaker. And the risks we talked about above will increase by 2–2.5 times.
5. If I received two doses of the vaccine, am I immediately protected from the coronavirus?
No. The final immune response will be formed approximately 14–17 days after the second dose of the vaccine.
6. Is it necessary to do an analysis for antibodies to coronavirus after vaccination?
Analysis for antibodies after vaccination should be done by those people who have problems with immunity (chronic diseases, autoimmune diseases, etc.). It is better to do it on the 20th day after the second dose.
7. Can the vaccine harm my health?
Serious side effects from vaccination are very rare. Less than 0.1%. But if you have health problems, such as chronic diseases, oncology, systemic diseases, you must consult a doctor and be under supervision for a day or two after vaccination.
8. How long will the vaccine work? Will revaccination be necessary?
According to the latest data, the protection provided by vaccines lasts at least 6 months. Then its effectiveness decreases. Although, according to some authors, if a person got sick and then got vaccinated, then the protection is more stable and long-lasting. As for revaccination, there is no consensus today. But the majority of researchers are inclined to the fact that the situation will be the same as with the flu — vaccination once a year before the epidemic season.
