Antibiotics kill bacteria. Bacteria can evolve resistance.
Vaccines prevent infection. Viruses that are unable to infect new hosts are very likely to die off. They can mutate as well, but if enough people in a population are vaccinated, it's very unlikely for the virus to mutate in such a way as to avoid the mechanisms by which the vaccine works.
Viruses and bacteria are different things. Bacteria just need a food source, and they're good to go; you'll have enormous numbers of them as long as their food source can sustain them. Viruses need a host cell. Vaccines don't kill viruses, they prevent viruses from spreading.
I have never heard any scientist or public health official claim that use of vaccines will lead to super-viruses. That, I assume, is something made up by the vaccine deniers.
