VACCINE WASTAGE

Subject : Science & tech

Context : A concern flagged by Prime Minister Narendra Modi, vaccine wastage is an expected part of any large inoculation drive.

Concept :

  • Vaccine wastage is directly linked to vaccine usage, which is the proportion of vaccines administered against vaccines issued to a vaccination site.
  • The vaccine wastage rate is defined as 100 minus the vaccine usage rate.
  • And the wastage rate directly determines the “wastage factor” that needs to be established for each vaccine in the immunisation schedule to accurately plan vaccine needs.
  • It is broadly divided into two categories: wastage in unopened vials, and in opened vials.
  • Wastage in unopened vials can occur due to six broad reasons: if the expiry date has been reached; if the vaccine is exposed to heat; if the vaccine has been frozen; breakage; missing inventory and theft; and while discarding unused vials returned from the vaccination site.
  • Wastage in opened vials can occur due to five broad reasons: while discarding remaining doses at the end of the session; not being able to draw the number of doses in a vial; submergence of opened vials in the water; suspected contamination; and poor vaccine administration practices.
