The National Vaccine Use Task Force said that approximately 651,650 people have received the Covishield vaccine since the exercise began over a month ago.
Those over 58 and non-priority groups still make up the bulk of those who were vaccinated at 365,178, followed by health workers at 136,084, teachers (97,786) and 52,602 security guards.
Something strange happened when listing the vaccination counts on Thursday : Nyeri County said it had vaccinated 233 more people than the 23,500 doses they received.
Waste can occur if a closed vial is not primarily due to ineffective temperature control, monitoring and inventory management during storage and transportation can be used. This may be due to expiration, excessive heat, freezing, breakage, missing inventory, or disposal after a contact session.
An open vial can also be wasted due to practices of immunization workers and discarded doses from vials from unused doses of multi-dose vials.
Vaccine waste rates are calculated to make it easier to forecast and to estimate sting needs and costs. Accurate calculation of the waste rate is important in order to reduce inventory and overstock, select the most suitable size for the vaccine presentation and vaccination session, and dimension the supply chain infrastructure at the country level.
At the global level is at this level The vaccine waste rate is a major factor in forecasting global vaccine access programs.
The variation in the number of doses given in some counties due to increasing concerns about vaccine shortages and waste in the country has led the Department of Health to issue a statement stating that each vial contains at least the specified number of doses, but it is possible to take additional doses depending on the size.
A vial is a small container, typically cylindrical and made of glass, which is specially used for storing liquid medicines.
In the case of Indie n manufactured Oxford / AstraZeneca vaccine marketed as Covishield, each vial contains between eight and 10 doses. This means that one vial can vaccinate a maximum of 10 people.
The World Health Organization (WHO) recommends discarding opened vials either six hours later or at the end of the vaccination session, come first, otherwise the remaining doses will be lost and must be destroyed.
This destruction corresponds to the so-called vaccine waste, which the WHO defines as the sum of discarded, lost, damaged or destroyed vaccines
During each vial at least the specified number of Contains doses, it is possible to take extra doses depending on the vial size, the task force said.
“Some manufacturers include some.” Obsolescence or extra amount in a vial to make up for loss when vaccines are in Syringes are drawn ”, the task force stated yesterday.
Depending on the type of syringes used, the verb remaining amount in the vial makes an additional dose or two.
“This has been observed while using the Covishield® vaccine in Kenya. The development was also observed in other countries where Covid-19 vaccinations were carried out, for example in the United States of America, “said the task force.
The possibility of an additional dose from the vial has also been attributed to the use of so-called “low dead volume syringes”. When a drug or vaccine is injected, some of it may remain in the syringe in the so-called “dead space” (also called dead volume) within the syringe and needle after an injection is completed.
“This in fact leads to a negative waste rate, with more people being vaccinated from a vial than expected, ”stated the task force.
Health However, workers were advised to Strictly adhere to guidelines for vaccine use.
“Should a half-used vaccine vial reach the disposal time, the remaining doses will be discarded and recorded as wasted. This waste is monitored daily, “said the task force.
There are important things to know about the Covishield vaccine used in Kenya: The vaccination course consists of two separate doses of 0.5 ml each. The shots are If stored between 2 and 8 degrees Celsius, it can be kept for six months.
According to the recommendations of the WHO, the second dose should be administered after eight to 12 weeks.
Because vaccines make up a considerable part of the costs of the vaccination program, it is important to ensure that waste is minimized without jeopardizing the vaccination rate.
The package insert and factsheet contain the vaccine and contain information on indications, dosage strength and administration, use, effects , Drug reactions, clinical efficacy, contraindications, risks and benefits, and use in specific populations.
