Also, in addition to patients who carry the HIV virus, omicron could also come from people suffering from other forms of immunodeficiency, said the immunologist of the German Society for Immunology, Carsten Watzl.

These are questions many people gone through coronavirus wondering about - how do we know that are we protected from Covid-19? Vaccinated  are also wondering whether they are already immune to the virus.

Antibody tests may have many answers and can help with all of these questions, although they don't provide absolute clarity about levels of immunity.
