The primary goal of all pharmaceutical companies, including those that manufacture vaccines is to make money for their shareholders. They value profits over the health/lives of patience. So yes that is exactly what I think
The fact that the bacteria evolve to evade the vaccines is a bonus for the manufacturer. Since they already have the technology to add in new antigens and serotypes (for an additional fee, of course), the fact that the pathogens change is just an additional market opportunity.
Expensive new vaccines that beget the need for even more expensive, newer vaccines are like a pot of gold at the end of the rainbow.
