People with depression are not looking for life saving anything. Having depression the better part of my life I can guarantee that anything that cuts the pain of this life short is agreeable. Not allowed by society or faith to take your own life so why not let a disease take you. Second, untested vaccine could make your already horrible life worse with side effects. People with anxiety struggle with everyday life. Much less going somewhere to have someone inject them with something that has not been tested and vetted by FDA approved testing regiments.
