We wish to share our very short study finding with the TechNet viewers for further input and mutual sharing of experiences for the global benefit of closing the imuunization gap.
Introduction of a newer vaccine or any change in vaccination policy provides an opportunity to train / reorient the service providers to revamp the efficiency for immunizing the vaccinated.
Responses by the TechNet members and global Immunization specialists inspired us to take-up a short study in the vaccination centre in our College. Initially we experienced – intra-dermal administration of just a drop of BCG vaccine=0.05ml especially to a newborn within 24 hrs was really difficult as the skin is too thin and delicate accentuated by the unpredictable movement but now we find it ‘not so difficult’ and administer with confidence.
The skin of 1½ month infant is a little more grown but the quantity of vaccine to be administered is 0.1ml=2 drops, double the 0.05ml.
On satisfactorily administering vaccines intradermally, we ‘dreamt’ of measuring the dimensions of the wheal accurately; enough for operational purpose.
Intra-dermal administration of vaccine raises a tense blanched Peau d’orange ‘bleb/wheal’, stays for a few fractions of a second. We measured the diameter instantly on pushing the vaccine completely by pausing the video and taking print screen, edited for making slides, taking care to maintain the accuracy of measurement. Following are the pictures, 3 each for BCG and IPV.
