We started adding vaccine names. But at the hospital, having observed young mothers and nurses in action we realized that providing an indication regarding type and site of immunization may be useful for an anxious young mother. Even if she may not herself read the names, she can look at the symbol and understand whether upcoming immunization is an injection, oral drops or syrup. 

Moreover, having such details on the immunization card makes it a good resource for training health workers in immunization processes. Injections are given either intra-dermal, intramuscular or subcutaneous but we did away with that information as parents would have found it too abstract perhaps and it would create an unnecessarily complex appearance and fight for space with other details.

Immunization serial number instead of checkboxes:
Check boxes were added for the healthcare providers to tick after administering each immunization, just to create a redundancy that can confirm which vaccines are given and which were postponed to be administered later. But given the crowds and long queues at a primary health centres, adding another task to the immunization protocol seemed unnecessary and check boxes were done away with.

If a card is lost or forgotten at home, semi-literate audiences find it very hard to recall the name of immunization previously administered. But they process numbers far better as numbers are connected to use of money and thereby survival. Hence we utilized the space of checkboxes to add numbers. Thus it is now possible to call someone at home and ask them the serial number of the immunization last administered.
