Switzerland will need to destroy 10.3 million doses of Moderna's vaccine against Covid-19, after they expired this week, the health ministry said Saturday.

The ministry said it had no choice but to eliminate the jabs after the doses expired last Wednesday, according to Keystone-ATS.

It told the news agency that 2.5 million of the doses were being stored at a Swiss army logistics base and 7.8 million were in an external storage depot in Belgium.

The ministry confirmed an initial report on Swiss news site Beobachter, which estimated that the doses set for destruction were worth around 280 million Swiss francs ($285 million).

The health ministry, which did not immediately respond to a request for comment from AFP, pointed to its early procurement strategy in the race to develop vaccines to counter the global Covid-19 pandemic.

Frequently Asked Questions

How does a vaccine work?

A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.

How many types of vaccines are there?

There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.

What does it take to develop a vaccine of this kind?

Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.

It ordered doses from various manufacturers to avoid becoming reliant on vaccines that might eventually prove ineffective and to guard against any delivery problems.

The fact that vaccines based on mRNA technology, from Moderna and Pfizer-BioNTech, turned out to be effective, left Switzerland with a large surplus of doses.

In June, the Swissinfo news site estimated that Switzerland had an excess of some 38 million doses of various Covid vaccines, that would expire before the year-end.

The ministry said that some 3.5 million doses of the new, adapted Moderna vaccine would be available when Switzerland kicks off its next booster campaign next month.

Switzerland, which has counted 13,556 deaths from Covid since the start of the pandemic, has fully vaccinated nearly 70 percent of its population of 8.7 million.
