What is a common outcome of not following proper cold chain procedures for vaccines?

Not adhering to proper cold chain procedures for vaccines can lead to decreased vaccine efficacy. Vaccines are formulated to be effective only within a specific temperature range. Exposure to temperatures outside this range, which can occur if vaccines are not properly stored or transported, can lead to the degradation of the vaccine components. This degradation may result in a diminished immune response when the vaccine is administered, meaning patients may not receive the protection intended from the vaccination.

Increased vaccine effectiveness, higher patient trust, and no effect on the vaccine are all inaccurate representations of the consequences of failing to maintain the cold chain. The consequences of temperature excursions impact the vaccine’s performance and the overall vaccination program, as ineffective vaccines can lead to outbreaks of preventable diseases, eroding public confidence in immunization efforts.
