What exactly is Tafasitamab?
Simply put, this is a vaccine that belongs to a special class of drugs called monoclonal antibodies . This is not like a pill that we usually take.

It's like giving our body's defenses special training, helping them recognize and attack the enemy.
This medicine is mainly used to treat a type of lymphoma called Diffuse Large B-cell Lymphoma . Sometimes your doctor may also prescribe it for other conditions. If you have any questions about it, ask your doctor.
