How Well Is My Baby Protected After Receiving Only Two Doses Of Petaxim And Prevenar13 Vaccines?

Hi. My baby got Petaxim and Prevenar13 vaccines when she was 2 and 4 months old. Due to possible serious side effects vaccination is stopped and she will probably nor be vaccinated anymore (9 months old now). I am wondering how well is she protected with 2 dose? Thank you!
