suicides are not something that can INFECT another, so that is just your own free will,dude. Each has the right and it is of no danger to others, unlike a virus.
Some people are too weak to handle life and refuse to help themselves. Some just are bored of life and it ain't worth it to them. Nothing new. People used to suicide much more in prior centuries, including 20th century.
They are not vaccines but simply inhibitors. As inhibitor they have worked better then nothing, but most likely have had little effect on the overall outcome. Those who have gotten the shots are spreading COVID faster then those who have not gotten the shots.
Worked for me.
