Is gamma globulin effective for COVID-19? Do ordinary people need to buy gamma globulin?

I don't think ordinary people need to buy it. Regarding whether gamma globulin is effective and whether people need to buy it, I personally think it should be combined with personal reality and not too blind and hasty. First of all, we should realize that gamma globulin contains a variety of antibodies in the blood, which can enhance the resistance, directly fight against the virus and inhibit the formation of immune complexes between the virus and its antigens and antibodies. However, gamma globulin has no therapeutic effect on infected people and cannot be used to treat COVID-19 infection. Although I am not a professional in this field, I came to this conclusion by consulting relevant materials, but many people do not understand this aspect, just blindly.

Although some people may snap up gamma globulin because their family members are seriously ill, hoping to supplement antibodies to make the immune system stronger, gamma globulin can't improve people's resistance to COVID-19, and even gamma globulin may bring unnecessary harm. Gamma globulin is really helpful to people with autoimmune deficiency or immunodeficiency because of their problems. When the immune system is defective or unstable, arm globulin can be used as an important supplement. Therefore, for ordinary people, if they choose gamma globulin just to cope with COVID-19, I personally think that this kind of behavior is blind. We should ask the doctor to find the medicine that really suits them, instead of blindly following the trend. If you take drugs at will, it will cause drug poisoning and cause great harm to your health and life safety, so it should be treated scientifically and rationally.
