A 2018 study into Cambodia's national immunization program found<unk>  rates of 0% to 60% depending on location and<unk> tion type. A study from India which collected Universal Immunisation Programme data from two different locations (Kangra and Pune districts) between January 2016 to December 2017 found<unk>  rates that differed according to<unk>  type, reuse type, vial size, transition from IPV (inactivated polio<unk>  dosage to fIPV (fractional inactivated polio<unk>  and according to the geographical location. In both districts<unk>  increased as vial size increased from 5 to 10 dose vials. In Kangra,<unk>  observed in oral polio<unk>  was 50.8% while in Pune it was 14.3%.<unk>  for a number of other<unk> tions in the program was higher than what had been factored into the initial programme forecasting. Parts of the United States has<unk>  tracking factored into the deployment process. Reasons for<unk>  are categorised as— broken vial/syringe, lost or unaccounted for, open but not all doses administered, or drawn into a syringe but not administered. Other reasons for<unk>  include contamination, expiration and temperature issues.<unk>  in the United States during its 2021 COVID-19<unk> tion program is less that 1%, and reported as low as 0.1%. In India covid<unk>  was 6.5% while in Scotland and Wales it was 1.8%.
