“…Only 62% of Indian children under the age of 23 months were fully vaccinated in 2016. 22 Furthermore, of those who were vaccinated, vaccination was often delayed-only 35% of Indian children in 2012 reported receiving DPT3 vaccination within a month of the recommended age, 8 and only 23% of children received BCG vaccination within 28 days of the recommended age during 2015-2016. 17 Vaccination timing is especially critical for reducing the burden of highly infectious diseases.…”

“…26 In 1995, the program was introduced nationwide, providing polio vaccines to 88 million children under the age of 3 years, and eventually covering all children under 5 years old. 27 Between 1999 and 2018, the coverage of the polio vaccine third dose among Indian children 12-23 months old increased from 57% to 89%, 8 and India was declared polio-free in 2011. 28 While our results suggest that PIRI activities can be successful, their long-term effectiveness and financial viability are unclear.…”

“…In addition to low coverage, failure to vaccinate children at recommended ages has remained a major challenge. In 2013, the proportion of delayed doses among children under 5 years old ranged from 35% for OPV first dose (OPV1) to 65% for DPT3 8 . Among 10‐ to 23‐month‐old children in 2016, the proportion of delayed doses (i.e., more than 28 days after the minimum eligibility age) ranged from 23% for BCG to 35% for the measles vaccine 9 .…”

Only an estimated 62% of Indian children under the age of 2 years are fully immunized. We examined the association between India's Mission Indradhanush (MI)-a periodic intensification of the routine immunization programwhich was implemented in phases across districts between March 2015 and July 2017, and routine vaccination coverage and timeliness among children. We used data from a 2015 to 2016 national survey of children (n = 29,532) and employed difference-in-difference regressions to examine binary indicators of receipt of 11 vaccines and whether vaccines were received at recommended ages. The full immunization rate was 27% higher among children under 2 years old residing in MI phase 1 and 2 districts (intervention group) as compared with those residing elsewhere (control group). The rate of receiving all vaccines at recommended ages was 8% higher in the intervention group. Receiving doses of oral polio vaccine (OPV) birth dose, OPV dose 1 (OPV1), OPV2, OPV3, bacillus Calmette-Guérin, and hepatitis B birth dose vaccines were 9%, 9%, 11%, 16%, 5%, and 19% higher in the intervention group than the control group, respectively. More research is required on the cost-effectiveness of investing in MI-type programs as compared with routine immunization.

“…Turnbull estimation has been used in recent papers from India. 68,95 The Turnbull estimator allows for both right censoring (e.g. the child is not vaccinated at the time of the survey) and left censoring (the child has been vaccinated, but with an unknown date that is at the very latest, the day of the interview).…”

Background: Traditional measurements of vaccine coverage at specific ages can mask poor vaccine timeliness. However, optimal measurement of timing is unclear due to variations in countries’ recommended vaccination schedules and lack of a commonly accepted standard for “timeliness”. We conducted a systematic review of literature on vaccine timeliness and delay in low- and middle-income countries from 2007 to 2017.Methods: A search of articles published between January 1 2007 and December 31 2017, was performed in PubMed, EBSCOhost, and Embase.Results: 67 papers were included, of which 83% used a categorical measure of delay and 41% evaluated continuous delay. The most common age at assessment was 1 month, with earlier age benchmarks typically used with birth doses.Conclusions: Categorical definitions of vaccination timing vary widely, with benchmarks of delay varying from days to weeks to months. Use of a continuous measure of vaccine delay may be more informative and comparable.
