The Pfizer-BioNTech vaccines were said to be worth $1.8 million.
According to the network, which said that Pfizer refused to extend the expiration date, Israel has not previously thrown out such a high number of vaccines during the pandemic.
“The State of Israel is managing its stock of vaccines while paying attention to the expiry of the product,” the Health Ministry said in response.
“The state signed confidentially agreements and cannot reveal the exact amount of vaccines,” it added.
Earlier this month, Israel shipped some 700,000 doses set to soon expire to South Korea, as part of a deal that will see Seoul send fresh vaccines in exchange later this year.
The expiration of the doses came a day after Israel began vaccinating people older than 60 with a third vaccine dose amid a resurgence in infections, with the number of serious cases topping 200 on Saturday for the first time since mid-April.
