Your child is due for DPT booster and OPV which are compulsory. You can get them form govt hospital also. Remaining are Chicken pox, Hepatitis A, Typhoid and pneumococcal(PCV) vaccines. These are optional. You can decide whether to give or not. I personally recommend chicken pox now as it's season going on and your child can catch it anytime. If you are affordable go for PCV also and lastly Typhoid and hepatitis A. All can be given with one month gaps. There is no urgency to give all at a time. so don't worry. schedules are guidelines to follow. Even if its late there is no problem. you can give them one by one.
