I would like to know if the hip and prevenar vaccine are importante or not?

Yes. The vaccines are only important if you dont want to risk your child dying from Hib or pneumococcal disease... These diseases are real, they are prevalent and, let there be no doubt, they are deadly. Don't screw around with Hib and pneumococcus, protect your child.
Yes. Both Hib and Prevnar (pneumococcal vaccine) are very important vaccines. They are very effective in preventing two serious illness.
