None of which I’ve had to have every 6 months.

There haven’t been any vaccines for AIDS

I don’t know if they’re all viruses though. Which vaccines have been made for viruses? With all the years that they’ve been doing vaccines I’d be interested to know which ones have been manufactured.
You probably have very little protection from the TB jab - it isn't very good.

To state the bleeding obvious, the causative agents of the diseases you mention vary. At a basic level, TB and Tetanus are bacterial whereas the remainder are viral.

Different causative agents target different structures in different ways within humans (hence them producing different diseases...). They also produce different immune responses.

An issue with RNA viruses like SARS-COV-2, is their high mutation rate, which means that vaccines have to be updated to keep up,in much the same way as 'flu vaccines do. The mRNA platform makes that much easier.

Eventually we'll slip into annual boosters for covid as we do for 'flu.
