Routine Immunization programme is rapidly expanding in the country, more and more vaccines are included in the National Immunization Schedule [NIS] in phased manner. Rota Virus Vaccine is being introduced in Karnataka. As customary, in Dakshinakannada district, training programmes were held in 2 batches on 17th & 19th July 2019 in collaboration with WHO country office, this will be followed by training at block and planning unit level.
With additional vaccines, additional cold space is required. Most of the multi dose vials have 10 or more doses e.g. 2mL OPV provides 20 doses, 5mL MR provides 10 doses, 2.5mL fIPV provides 25 doses. Currently supplied RVV is unique in the sense 5mL per vial after reconstitution has 2 doses of 2.5mL each. Hence the storage code is revised to accommodate Vaccine Vials if not the diluents.
A Planning Unit in Karnataka is not having more than 30,000 populations, at 20 birth rate; estimated annual target of 0-1year children will be 600, on an average 50 per month. RVV vial requirement is 50 infants×3doses=150×1.11wmf [@90% usage] =166.5 doses +25% buffer stock=166.5+41.65 = 288.15; rounded off to 290. @ 2 doses per vial, 145 vials are needed with 145 diluents and 290 6mL oral syringes. Diluents and oral syringes can be kept outside the cold chain and required number of diluent vials need to be kept in the ILR at least 24hrs prior to the session.
Karnataka has the luxury of having adequate planning units, majority do not have more than 350 children per year at least in the rural area. Author had revised the earlier storage code of 2012 designed for ILR’s with 2+1 baskets [140L] for 300L ILR with 3+2 baskets, submitted to the state government which issued official circular on 29 April 2018 to all the districts and planning units. Now, in view of above it is redesigned for operational use and submitting the draft to the government for needful.
