how are covid monoclonal antibodies made

In the specific case of malaria monoclonal antibody treatments, further innovation is needed to make them even more potent, which could help drive down the cost and make them available to older children and adults who might be particularly vulnerable to certain diseases, such as pregnant women and migrant workers.

Some hospitals made them more accessible by setting up drive-through monoclonal antibody clinics. The class 1 and 2 mAbs, now commonly used against COVID-19, are highly potent and can neutralize a specific variant of the virus by targeting the receptor-binding domain of the SARS-CoV-2 spike protein.
