Covid vaccine doses have been destroyed after a lab worker accidentally turned off the refrigerator they were being stored in.
The employee had shut off the power supply to the fridge, causing the Pfizer 232 vials to degrade.Workers noticed the power supply was off while conducting a "quality assurance check" on Friday morning at the Palm Beach County Health Care District in Florida.To preserve the vaccines the doses must be stored at a temperature of -70 degrees Fahrenheit before being transferred to a regular fridge five days before use.If exposed to lower temperatures the vaccines may become ineffective.
