Do I have sufficient antibodies after vaccination Covid-19? (
In 5% of people, not enough antibodies are produced to be protected against COVID-19. Check your titer regularly to see if you still have enough antibodies.

Two tests are suitable for measuring antibodies after vaccination.
Why some people contract the coronavirus after a vaccination is still not clear. Still, there is a way to find out if the vaccine had an effect on your immune system. Some antibody tests designed to detect natural corona infections can also measure antibodies made in response to the vaccination three weeks after a shot.
For some vaccines like Astra Zenica and Janssen, it is better to wait a month to measure your antibodies after vaccination.
The Abbott test and the Euroimmun test measure the spike antibodies Sars-Cov-2 that are also produced after vaccination.
The Euroimmun test is also available as a finger-prick test. You can drip the blood yourself on a special card that you send to the lab.
In order to know whether you are sufficiently protected, it is important to see whether your results are above the reference values for the test in question that you have taken.

Sensitivity of Abbott CMIA IgG and EI ELISA IgG
CMIA is an abbreviation for: Chemiluminescent Microparticle Immuno Assay, an advanced serological diagnostic technique.
ELISA is an abbreviation for Enzyme-Linked Immuno Sorbent Assay. ELISA is an immunochemical reaction based on the specific binding between antigen and antibody. By demonstrating this in the blood it is possible to contribute to the diagnosis of an infectious disease.
