Here is a detailed catch-up immunization plan for a 9-month-old completely unimmunized child, based on the IAP-ACVIP 2025 schedule (India) and supported by CDC/AAP 2026 guidance.

Catch-Up Immunization for a 9-Month-Old Unimmunized Child

Key Principles

Never restart a series - pick up where needed, or start from scratch since nothing was given.
Multiple vaccines can be given on the same day at different sites (not contraindicated).
Rotavirus vaccine CANNOT be started after 15 weeks of age - this opportunity is permanently missed for this child. The maximum age for the final RV dose is 8 months, 0 days.
Minimum intervals between doses must be respected.
Catch-up does not mean giving everything at once - prioritize and space appropriately.

Vaccines MISSED and Cannot Be Caught Up

Vaccine	Reason
Rotavirus (RV)	Cannot start after 15 weeks; maximum age for final dose is 8 months. Permanently missed.
Birth dose BCG	Give now if not given (still beneficial - some protection)
Birth dose OPV-0	Give OPV now as part of the series

Visit 1 - NOW (9 months) - Give Immediately

Vaccine	Dose	Notes
BCG	1 dose	If not previously given at birth
DTwP/DTaP	Dose 1 (primary series)	Start the 3-dose primary series
IPV	Dose 1	Start the series
Hib	Dose 1	Start the series
Hepatitis B	Dose 1	Start the 3-dose series (0, 1, 6 month schedule)
PCV (Pneumococcal)	Dose 1	Start the series
OPV	Dose 1	Oral, can give alongside IPV
MMR	Dose 1	9 months is the IAP-recommended age for MMR-1; give now
TCV (Typhoid Conjugate)	Dose 1	IAP recommends at 9-12 months

Visit 2 - 4 Weeks Later (~ 10 months)

Vaccine	Dose	Notes
DTwP/DTaP	Dose 2	Min interval: 4 weeks from Dose 1
IPV	Dose 2	Min interval: 4 weeks from Dose 1
Hib	Dose 2	Min interval: 4 weeks from Dose 1
Hepatitis B	Dose 2	Min interval: 4 weeks from Dose 1
PCV	Dose 2	Min interval: 4 weeks from Dose 1

Visit 3 - 4 Weeks After Visit 2 (~ 11 months)

Vaccine	Dose	Notes
DTwP/DTaP	Dose 3	Completes primary series
IPV	Dose 3	Completes primary series
Hib	Dose 3	Completes primary series
PCV	Dose 3	Completes primary series

Visit 4 - At 12-15 Months

Vaccine	Dose	Notes
Hepatitis B	Dose 3	At least 8 weeks after Dose 2, and at least 16 weeks after Dose 1
MMR	Dose 2	At least 4 weeks after MMR-1; IAP recommends MMR-2 at 15 months
Varicella	Dose 1	IAP recommends starting at 12 months
Hepatitis A	Dose 1	IAP recommends starting at 12 months
PCV Booster	Booster	At 15 months

Visit 5 - At 16-18 Months

Vaccine	Dose	Notes
DTwP/DTaP Booster 1	Booster	6 months after completing primary series
IPV Booster	Booster
Hib Booster	Booster
Varicella	Dose 2	At least 3 months after Dose 1
Hepatitis A	Dose 2	6 months after Dose 1

Influenza

Give 2 doses of Influenza vaccine 4 weeks apart (since this is the first time receiving flu vaccine). Then annually every year thereafter.

Summary Table - What's Possible vs What's Lost

Vaccine	Catch-Up Possible?
BCG	Yes
Hepatitis B	Yes (3-dose series)
DTwP/DTaP	Yes (3 doses + boosters)
IPV/OPV	Yes
Hib	Yes
PCV	Yes
Rotavirus	No - missed permanently
MMR	Yes (give now at 9 months)
Typhoid (TCV)	Yes
Varicella	Yes (from 12 months)
Hepatitis A	Yes (from 12 months)
Influenza	Yes (2 doses first time)

Important Notes

Rotavirus is the one vaccine that cannot be caught up - the window closes at 15 weeks for the first dose, and at 8 months for the last dose. This child has unfortunately missed it entirely.
The IAP 2025 schedule (also referenced as 2026) is the standard used in India; the CDC/AAP 2026 schedule applies in the USA - the core catch-up logic is the same.
Minimum intervals must be respected; giving doses too early invalidates them.
A pediatrician should review the child's records and overall health before each visit.
Under India's Universal Immunization Programme (UIP), BCG, OPV, Hep B, Pentavalent (DPT+Hib+HepB), IPV, PCV, and MR vaccines are available free at government health centers.

I now have the complete NIS data from both the official government PDF and Park's textbook. Here is the focused answer:

Catch-Up Immunization for a 9-Month-Old Unimmunized Child - As per India's National Immunization Schedule (NIS/UIP)

The NIS is India's Government of India / Ministry of Health & Family Welfare schedule - all vaccines are provided free of cost at government health centers.

NIS Vaccines Under UIP

Vaccine	NIS Age	Route	Dose	Site
BCG	Birth (up to 1 year)	Intra-dermal	0.1 ml	Left upper arm
Hepatitis B birth dose	Within 24 hours of birth	IM	0.5 ml	Anterolateral thigh
OPV-0	Birth (within 15 days)	Oral	2 drops	Oral
OPV 1, 2, 3	6, 10, 14 weeks	Oral	2 drops	Oral
Pentavalent 1, 2, 3 (DPT + Hib + HepB)	6, 10, 14 weeks	IM	0.5 ml	Anterolateral thigh
fIPV 1, 2	6 and 14 weeks (fractional)	Intra-dermal	0.1 ml	Right upper arm
RVV (Rotavirus)	6, 10, 14 weeks	Oral	3 drops	Oral
PCV 1, 2	6 and 14 weeks	IM	0.5 ml	Anterolateral thigh
MR-1	9-12 months	Sub-cutaneous	0.5 ml	Right upper arm
JE-1	9-12 months	Sub-cutaneous	0.5 ml	—
PCV Booster	9-12 months	IM	0.5 ml	Anterolateral thigh
fIPV-3	9-12 months	Intra-dermal	0.1 ml	Right upper arm
Vitamin A 1st dose	9 months	Oral	1 lakh IU	Oral

*JE vaccine only in endemic/selected districts.

Catch-Up Plan for This 9-Month-Old (NIS Vaccines Only)

Since the child is 9 months old and completely unimmunized, apply the following NIS catch-up logic:

Visit 1 - NOW (Age 9 months)

Give everything due at this age AND start the missed series simultaneously:

Vaccine	Action	Notes
BCG	Give now	NIS permits up to 1 year of age
OPV	Start series (Dose 1)	OPV can be given till 5 years
Pentavalent-1 (DPT+Hib+HepB)	Start series (Dose 1)	Can be given till 1 year of age
fIPV	Dose 1 (fractional)	0.1 ml ID, right upper arm
RVV (Rotavirus)	Dose 1	⚠️ NIS permits RVV up to 1 year under UIP - this is different from IAP; give now if < 1 year
PCV	Dose 1	Start series
MR-1	Give now	This is the scheduled age (9 completed months)
JE-1	Give now	Only in endemic districts
Vitamin A	1st dose (1 lakh IU oral)	Due at 9 months

Visit 2 - 4 Weeks Later (~10 months)

Vaccine	Action
Pentavalent-2	Dose 2 (4-week interval from Dose 1)
OPV-2	Dose 2
RVV-2	Dose 2

Visit 3 - 4 Weeks After Visit 2 (~11 months)

Vaccine	Action
Pentavalent-3	Dose 3 - completes primary series
OPV-3	Dose 3
RVV-3	Dose 3
fIPV-2	2nd fractional IPV dose (at least 8 weeks after first fIPV)
PCV-2	Dose 2

Visit 4 - At 9-12 Months (same visit or next due)

Vaccine	Action
PCV Booster	Give after completing 2 primary PCV doses
fIPV-3	3rd fractional dose at 9-12 months (as per NIS schedule)

Visit 5 - At 16-23 Months

Vaccine	Action
MR-2	2nd dose (at least 4 weeks after MR-1)
JE-2	2nd dose (endemic districts only)
DPT Booster-1	First booster
OPV Booster	Booster dose
Vitamin A	2nd dose (2 lakh IU), then every 6 months till 5 years

Key NIS-Specific Points

Point	Detail
Rotavirus window (NIS)	Under NIS/UIP, RVV is permitted till 1 year of age - unlike IAP which restricts it to < 8 months. So this child can still receive RVV under government schedule.
Pentavalent	NIS uses Pentavalent (DPT + Hib + HepB combined) - given till 1 year of age
fIPV	Government schedule uses fractional (intradermal) IPV - 0.1 ml ID, not full 0.5 ml IM
Hepatitis B	Covered within Pentavalent - no separate HepB doses needed under NIS
No Varicella/HepA/TCV/MMR	These are NOT part of NIS - they are IAP-only (private) vaccines
MR vs MMR	NIS provides MR (Measles + Rubella, no Mumps). MMR requires a private clinic.
All free	All NIS vaccines are free at government ASHA/ANM/health center
