Its not just about having more genes. Viruses can mutate too since they also contain genetic material- that's why there are new flu vaccines every year.

Its easier to treat bacterial infections because they are more complex living organisms that replicate on their own, so we can target antibiotics to the parts of the bacterial cell that are different than ours. Viruses cannot replicate on their own, they need to use use our cellular mechanisms to replicate so they are harder to target with anti-virals (though we do have some.) Because its harder to fight viruses once they've invaded its usually easier to use a vaccine to teach the immune system to recognize and destroy viruses preemptively.

The question, I think, was why aren't there more vaccines for common bacterial illnesses. One answer (I suspect only a partial answer) is that bacteria have more genetic material and mutate at much greater rates than viruses, generally speaking, which makes them less stable and harder to control in the manufacture of vaccines.

Flu vaccine, with its relatively low efficacy rate, would actually be a great example of this: pathogens, whether bacterial or viral, that have a high mutation rate are very difficult to successfully inoculate against.

ETA: This is my simple understanding of a complex topic based on what I've been reading (I've posted some links upthread) but I seem to recall that this is really vaccine amother's niche. I'm hoping she'll weigh in here, if we haven't scared her away.

I posted as you posted. But I am not getting how it is easier to create vaccinations against bacterial infections versus viral infections.

It's easier to create vaccines against viruses because the literally are just proteins, a genome and maybe a lipid. So you can just shred up the viral protein make sure it's dead and voila immune response. Bacteria are much more complicated.

this was so so painful to read,
