Half of India's Children are not Immunized

Issue 15, 10 August 2009

 
Editorial Note

Debra Kristensen updates us on research on a new hepatitis B vaccine that is less cold-chain dependent. Tasnim Partapuri looks forward to TechNet21 readers sharing information on integrated health outreach activities in relation to immunization. Also included in this issue are the latest Global Immunization News and news items from VaccineIndia.

You can also keep pace with the responses to the Optimize posts on delivering OPV safely without icepacks and the new generation batteries for solar refrigeration, and the discussion on investing in new vaccines.

Thank you for the congratulatory messages.

The data indicate that the new hepatitis B vaccine formulation will be better able to withstand disruption in the cold chain and could potentially be stored at controlled room temperature for a significant part of its shelf-life.

   • what looks promising, what are the lessons learned

Only 54.1 per cent of India's children are fully immunized. The other half -- this includes the 11.3 per cent who never received any form of vaccination -- run the risk of disease as they have failed to complete even the basic immunization schedule.
