Influenza virus can easily mutate and change its spike proteins, this our B memory cells aren't able to bind to this new mutated virus and it's as if it's a whole new virus. Tetanus is caused by a bacteria called clostridium tetani which ofc is a bacteria which posses the power of mutation but can't mutate as rapidly as RNA viruses.

Simpler words influenza is a theif that robs you every week but changes his outfit so you never see him coming but tetanus is a dumb theif which doesn't change his attire when he tries to rob you and gets caught before he could rob you because he robbed you once and you remember his looks now(vaccine)

Maybe this is a stupid question, but how did they know much about bonds if they didn't even know what an atom is made out of? From what I know, bonds are determined by the electron probability clouds and depending on the atoms there can be different types of bonds. But they didn't even know what an electron is!

True. My personal answer to this is that I consider a "person" to be the processes that occur in the brain from which consciousness arises via some mechanism that is not yet well-understood, with the body more or less just being a vessel for those processes to occur in and for the consciousness to interact with the world.

And so my personal opinion is that the only real use for keeping a braindead body alive would be to keep its organs viable until transplantation, but I do understand that that is probably an opinion that is quite far to the materialist side of things.

Influenza is localised to the lungs, the virus attaches and multiplies there. From there to lymph nodes in any discernable concentration is a long way. Tetanus is a main circulatory system infection so it will come into contact with lymph nodes more often and in higher concentrations allowing a greater immune response.

You need more top ups of influenza vaccines to increase the possibility of an immune response from the lower concentrations of virus entering the lymph nodes.
