Greta Thunberg scolds rich countries for 'vaccine nationalism'

Everyones' favourite teenage Swede, Greta Thunberg, has come out of her hiatus to declare that vaccine nationalism is unacceptable.

A grateful human race will be pleased to learn that the environment's saviour has called vaccine nationalism "completely unethical."

"It is completely unethical that high-income countries are now vaccinating young and healthy people. If that happens at the expense of people in at-risk and on the front lines in lower and middle-income countries," said Greta.

The global population waited with bated breath as Greta carried out her verdict: "This is a moral test," she warned sagely. "Vaccine nationalism is running the vaccine distribution."

Greta then went on to order Western governments and pharmaceutical companies to "step up their game," which they surely now will do.

Greta finished her statement by harping on about the usual environmental stuff, declaring that deforestation, gas-guzzling, and throwing plastic straws out the window was making a climate where diseases are much more common.

Before becoming an epidemiologist, Greta was famous for such things as taking a carbon-free pontoon across the Atlantic (no one knows how much carbon actually went into making the thing), and convincing children to bunk off school.
