Do we know which immunoglobulin fights this type of virus (Covid-19)? IGG, A etc. Thanks
Our own antibodies, especially IGA and IGG, are extremely important in our ability to clear respiratory viruses. IGG is our main type of antibody representing about 75% of the antibodies found in the blood and IGA lines the mucus membranes, including the respiratory tract. When exposed to a viral threat, we are supposed to launch an immune response with increased antibody production directed at the invading organism. Our ability to produce these antibodies is often limited in CLL due to the disease and its treatment.
IVIG (intravenous immunoglobulins) is a pooled blood product with concentrated IGG. We receive other peoples’ antibodies to help us fight off the germs they have been exposed to.
Since until very recently no-one has seen this novel virus, it is extremely unlikely that IVIG would provide any protection as there would be no Covid-19 specific antibodies in the product. That will change over time.
