On December 27, 2020, the vaccination process against SARS-CoV-2 began. So far, over 350 have been vaccinated in Poland. people. How long does immunity following COVID-19 vaccination remain open? Will we get vaccinated every year, just like the flu?
- Most experts believe that the SARS-CoV-2 vaccine will provide protection against infection for 12 months, and therefore vaccination will have to be repeated regularly
- Immunity after vaccination is achieved on average a few days after the second dose

Vaccinating against COVID-19 every year?
Health Minister Adam Niedzielski in an interview with Radio Plus journalist said that the duration of immunity to SARS-CoV-2 coronavirus infection after receiving the vaccine is a big question mark.
— We assume that the resilience will be longer, because in the optimistic scenario we are talking about two years – he said and added that it may also turn out that the vaccine will not be effective against mutations of the coronavirus, which will mean that vaccinations will have to be repeated every year, as in the case of flu.

The more scientists know about the immunity acquired after contracting COVID-19, the more realistic the vision of annual vaccination against the SARS-CoV-2 coronavirus seems to be. At the Advisory Committee on Vaccines and Related Biological Products, one of the committee members, Dr. A. Oveta Fuller, explained that scientists expect it will not be a “vaccine for life”. What do we know so far about immunity after receiving the vaccine?

Immunity after receiving the vaccine
The duration of immunity following SARS-CoV-2 vaccination is largely unknown. This is due to the lack of time to study the immune response. It is known, however, that two doses of Pfizer and Moderna mRNA vaccines are extremely effective and induce an immune response a few days after taking the preparation.
It is possible to test your immunity to the coronavirus after it is infected or vaccinated. On Medonet Market you will find a blood test package for COVID-19 resistance, which you can buy at an attractive price.
SARS-CoV-2 vaccines help our body to develop immunity to the virus that causes COVID-19 without having to get sick. Different types of vaccines work in different ways to provide protection. What they have in common is that they stimulate the production of T lymphocytes and B lymphocytes, which will “remember” how to fight the virus in the future.
Pfizer’s Comirnata vaccine showed early protection 12 days after the first dose and seven days after the second dose, according to data published in the New England Journal of Medicine. In turn, in participants of a clinical trial on the effectiveness of the SARS-CoV-2 Moderna vaccine, high levels of antibodies were maintained for three months after the second dose.
Moderna’s medical director, Tal Zaks, gave a very specific answer to the question about the length of protection: – We expect vaccination to last at least a year.

– It is very likely that in the case of the COVID-19 vaccine, given that the immunity it generates is limited, annual vaccination may be necessary – said Chunhuei Chi, director of Oregon’s Global Health Center at the State University College of Public Health and Humanities.
Most experts agree that the SARS-CoV-2 vaccine will have to be repeated to ensure effective protection.
According to the Centers for Disease Prevention and Prevention, it usually takes several weeks for the body to build up a solid immunity after vaccination. The CDC also reminds that even after receiving the vaccine, it will be important to distance yourself from wearing face masks.
