Ravulizumab vaccine (ULTOMIRIS): Has this been prescribed for you too? Let's find out simply

When your doctor prescribes you a vaccine called Ravulizumab (most commonly available under the brand name ULTOMIRIS), it's normal to have a lot of questions. This is a very special, yet very powerful drug. This is not a medicine for the common cold or flu. So I'm going to talk about it in a simple way that you can understand.

To be precise, what kind of medicine is Ravulizumab?

Simply put, Ravulizumab is a drug that controls an abnormal process that occurs in our body's immune system. Sometimes our own immune system becomes overactive and starts attacking our own healthy cells. At such times, this drug helps control that unwanted activity.

This belongs to a special class of drugs called monoclonal antibodies . That is, it is a protein made in the laboratory using special technology. Like a homing missile, it goes to the exact location of the problem in the body and controls it.

Doctors use this medicine to treat several main conditions:

• Atypical Hemolytic Uremic Syndrome (aHUS): This is a condition in which red blood cells break down and blood clots form in small blood vessels , causing conditions such as anemia .
• Paroxysmal Nocturnal Hemoglobinuria (PNH): This is also a condition involving the destruction of red blood cells.
• Myasthenia Gravis : This is a disease of the nerves and muscles. It causes the muscles to weaken very quickly and cause fatigue.
• Neuromyelitis Optica Spectrum Disorder (NMOSD): In this disease, the nerves in the eyes and spinal cord become inflamed.
