hello dr.. was checking the vaccination schedule of my child.. the paediatrician that we used to go to initially has given only 3 doses of PCV vaccine.. initial two doses 4 weeks apart and a booster at 15 months of age..a total of 3 doses since we have shifted we have a new dr now who recommended 4 doses and says we have missed one dose.. I am a little worried as to what to do next.. my daughter is 4 years 9 months now
