The vaccination campaign against Covid-19 started at the end of 2020 in many developed countries. But the donation of the first doses to poor countries did not start until June 2021. From that month until June 2022, More than 1.1 billion coronavirus vaccines have expired.
Among the reasons for wasting dose is delayed shipments. Which is that on many occasions the vaccines arrived with a very short shelf life, and so did the countries They did not have enough time to distribute and manage to the population.
Thus, the Airfinity numbers in 10% of expired doses of total production. The organization based its projection on the waste rate in the United States recorded since June 2021 (which is up to 10%) and public reports taking into account the shelf life of the vaccine of six months.

“Vaccines in single-dose vials with a longer shelf life, which can be transported and stored more easily, will reduce waste,” Linley added. In fact, there is already an agreement between Pfizer and the United States on the supply single dose. “Something we hope other countries will repeat.”
For his part, Airfinity CEO and co-founder Rasmus Bisch Hansen noted that “while waste is undesirable, it is a consequence of Unprecedented vaccine production that saved millions of lives.” “Vaccine protection against Covid-19 decreases over time and decreases booster dose It will still be the best way to protect the weak.”
Thus, Hansen added that “if we want a global vaccine system that reacts quickly, we will have to accept some level of missed doses.”
Vaccines expire in 2021
In fact, Only developed countries ‘ditched’ 61.5 million vaccines against Covid due to expiration in 2021.
Specifically, according to Airfinity data, 61,534,034 doses purchased last year in the European Union, United Kingdom, United States and Canada have expired. Some vaccines that could have served Immunization of more than 30 million people.
