A Pfizer representative said the drug developer will use GPS-enabled thermal sensors in every container of vaccines to track the location and temperature of each vaccine shipment.
“These GPS-enabled devices will allow Pfizer to proactively prevent unwanted deviations and act before they happen,” said Francesca Marzullo, manager of Pfizer Global Supply Communications.
But the sensors aren’t on each individual vial.
“These electronic temperature sensors are typically used for large shipments of vaccines that are going from the manufacturer to the places where these vaccines are locally distributed,” Baughman said. “They are not used on individual vaccine vials.”
