And there's the problem. What they need are vaccines for the most deadly diseases, like tuberculous and polio. They don't have to have vaccine for disease like HPV. Even measles and chickenpox have extremely low mortality rates. Prioritize. By focusing on the most important vaccines, the cost would be much lower and more people would be able to get them and more lives would be saved.
There are some cancers that are caused by HPV (i.e cervical cancer) so the mortality rates are quite important in that case.
