Well, they are trying. Honestly! It's just that it's not very successful yet, and something is embarrassing. This is me about the streptococcal tonsillitis vaccine. This sore throat can fester and block the throat or melt the heart valves. I would like to defend myself.
That does not work
Everyone has heard of bivalent or quadrivalent vaccines. They develop immunity against several varieties of some kind of infection.
So in the case of that harmful streptococcus, you have to do, for example, thirty-valent vaccines. Because this infection is very diverse. And even these vaccines don't always work.
What confuses
It is embarrassing that a too good vaccine that would recognize this harmful streptococcus from two notes, in fact, can attack not a streptococcus, but our own organs. This is how the so-called non-purulent complications of streptococcal sore throat begin.
Well, that is, there are purulent complications. This is, for example, an abscess next to the amygdala, which can grow so large that it suffocates its owner. Nice complication.
What? Yes, good! Because a purulent complication can be quickly cured. But non-purulent complications, when our own immunity under a hot hand, together with streptococcus, begins to burn heart valves or kidneys, these complications are more difficult to control.
It turns out that when scientists make a vaccine against the harmful streptococcus that causes angina, then they balancing between too weak a vaccine and a really lethal vaccine that does not spare either its own or strangers.
Have you got an abscess in your throat? What did they water it with and how was it looked after?
