NTAGI Recommendations Overlooked Crucial ICMR Data

We thank the NTAGI for publishing its recommendation on Hib vaccine in Indian Pediatrics(1) as this journal allows ‘extended peer review’ in its correspondence columns. We are concerned that the technical advisory body has overlooked crucial evidence gathered in studies done by the ICMR while making its recommendations.

In 2002, one of the members of this subcommittee, Professor Thomas Cherian wrote in this journal quite categorically, that based on the data available Hib vaccine could not be recommended for routine use in the EPI in India(2). He recommended more studies be done to establish the need for vaccination. Press reports in 2005(3) suggest that one such study was indeed undertaken by the ICMR in Anaicut block, Vellore. We did not find the results of the study published in an indexed journal in spite of an extensive search of the literature. We presume the data must have been made available to the NTAGI.

The first part of the ICMR study was supposed to look at the incidence of pneumonia (regardless of etiology) and deaths from pneumonia. The WHO suggests that 19% of the under five mortality (U5MR) in India is due to pneumonia(4). Given the fact that the U5MR is 71.9/1000 this implies that 14/1000 children under 5 years of age die of pneumonia.

The NTAGI report of 2008(1) says ‘there is (now) sufficient evidence of relatively high Hib disease burden in India to warrant early introduction of Hib vaccine into the UIP’. Professor Cherian Thomas represented WHO on this NTAGI sub-committee. We expected new research done after 2002, which had made the author change his mind and which allowed the expert group to make this recommendation, would be quoted in the report. However in looking through the data reviewed during the subcommittee process (Appendix 2), we find no reference to any population based study from India done after 2002 under the heading ‘Hib disease burden and Epidemiology’. The studies quoted on pneumonia and respiratory infections were all published between 1984 and 1999.

We believe that the data from the ICMR study in Anaicut on the incidence of pneumonia and deaths from pneumonia are crucial for advising policy. We wonder why it was not made available to the NTAGI. If it were available, we are curious as to why it has not been referred to in the report. We urge that this be done urgently and published as a reply to this communication, so it can advise policy. Selective use of data is not compatible with the principles of evidence based medicine.
