I don't think it's unique to the UK. I can think of at least two instances of controversy surrounding Covid-related procurement deals in the Netherlands and Thailand. I'll highlight some of the controversies.
The Netherlands: shady deal surrounding the procurement of face masks
In the Netherlands there was a row over someone who created a nonprofit organisation to import and provide face masks. It later turned out that the same person was involved in a for profit company tied to the nonprofit which allowed them to make money off of the face mask deals even though they presented themselves as a nonprofit.
And because of health risks associated with the masks from their organization, the masks were never used. The deal involved around one hundred million euro. The information above is based on the following Dutch Wikipedia excerpt (linked via Google Translate).
The deal is the subject of an external inquiry. This deal took place early on in the pandemic. For example, this Dutch state broadcaster article in May of 2020 (translated) describes that person's effort of providing masks.
Thailand: defamation suits regarding criticism of vaccine procurement
According to Reuters, there are at least two lawsuits underway surrounding criticism of vaccine procurement and production:
The Government Pharmaceutical Organization (GPO) suit accuses Boon Vanasin of providing false information, claiming that the GPO, as coordinator for Moderna vaccines for private hospitals, sought to maximize profit from the public, the GPO said in a statement.
Another critic of the strategy, opposition politician Thanathorn Juangroongruangkit, is facing charges of insulting the monarchy after accusing the government of over-reliance on a royal-owned firm to produce AstraZeneca vaccines. The crime is punishable by up to 15 years imprisonment.
Some more accusations, as reported by the Thaiger in September 2021:
Complex, tricky accounting, embezzlement or a government going about its work in the middle of a pandemic? Accusations by the Pheu Thai opposition party are demanding Thai PM Prayut Chan-o-cha explain a 2 billion baht [about $60 million] gap between what was allocated for Sinovac vaccine purchases and what was actually spent.
All of this seems to be in play in 2021. It should be noted that Thailand only started seeing increased case numbers in 2021 (see the timeline in a previous answer of mine), so before that the government might not have put that much effort into procuring medical supplies.
