Well those people probably dont understand much about vaccines.
Now, for a normal healthy adult with an intact immune system, they likely arent a necessity because the flu is unlikely to kill them.
The Spanish flu pandemic of 1918 (which was of the H1N1 flu subtype, also known as "swine flu") mainly killed healthy young adults because it caused the immune system to overreact. Between 3 and 5 percent of the world's population died.
Yes, being able to identify one instance that is literally 100 years ago is why I said unlikely to kill them.
There was a major H1N1 outbreak in India in 2015 that killed 1,900 people. The H5N1 subtype ("bird flu") is also known to cause deadly cytokine storms.
