>>11484990I think you're confusing "Vaccine" and "treatment"
Vaccine is where you get a shot with the genetic material of the disease so that your body can recognize the virus and have anti-bodies ready to go if you encounter the live virus.
In this situation, the virus can mutate from year to year making the previous vaccine inneffective because your body is confused and doesn't recognize that virus as the previous one (Its STILL good to have it though because your body will still have experience with a variant of that virus and will take less time to make new antibodies. This is why native americans were so shit fucked by europeans coming over, since their bodies didn't have experience fighting these viruses before)
A TREATMENT is something different, its medication designed to suppress or reduce the severity of the damaging symptoms of the virus in order to avoid damage/death from it, such as the inflammation of the lungs, allowing you to go through the disease relatively cleanly and give your body free time to make its antibodies. (Look at cold medicine, which is just designed to reduce the symptoms for example).
If the virus mutates, its highly unlikely for the treatment to become inneffective, since its still targeting the same symptoms.
So if we figure out a treatment to prevent pneumonia from this disease its most likely not going to become invalid, while with a vaccine we'll have to reinvent it every year (Albeit with it being more useful)
