It could cost as little as $50 billion to save the global economy.

That’s the amount needed to vaccinate the world, a measure that’s key to ending the pandemic and tackling the imbalances “plaguing the recovery,” according to OECD Chief Economist Laurence Boone.

“When you balance things out, $10 trillion for supporting the economy going through the pandemic compared with a tiny $50 billion to bring the vaccine to the entire world population, that looks completely disproportionate,” she told Bloomberg Television in an interview Wednesday.

While the OECD didn’t directly account for the Omicron strain in its new forecasts, it emphasized continued pandemic risks and urged governments to address low inoculation rates in some regions so as not to create “breeding grounds for deadlier strains”

The first number is the amount spent by Group of 20 countries to mitigating the economic impact of COVID-19.

The emergence of Omicron increases the uncertainty already weighing on the global economic outlook and highlights vaccination shortcomings, she said.

While the Paris-based organization didn’t directly account for that strain in its new forecasts, it emphasized continued pandemic risks and urged governments to address low inoculation rates in some regions so as not to create “breeding grounds for deadlier strains.”

On top of tighter virus restrictions including renewed lockdowns in some parts, OECD members are battling soaring inflation and hold-ups in global supply chains that are starving factories of components.

Meanwhile, more and more countries are targeting the unvaccinated in the battle against the coronavirus.

Germany and Israel are moving closer to making COVID-19 vaccine shots compulsory, Greece is introducing fines and Spain is banning some unvaccinated travelers. Despite protests, making life harder for those who don’t want a shot is a tactic increasingly favored by governments, spooked by the spread of the omicron variant.

Here are some of the measures against the unvaccinated deployed by governments around the world.

Greek Fines

The government is making vaccines mandatory for all Greeks above 60 years of age. From next month, refuseniks will pay a 100-euro ($113) fine every month they don’t get a shot, with the funds going to hospital services. In Greece, only 60,000 among the 580,000 unvaccinated people over 60 years old received the vaccine in November.

Finland’s Bars

Bars and restaurants in Finland refusing to use COVID-19 certificates will no longer serve booze after 5 pm in the latest attempt by the government. Health authorities in the northern town of Kajaani offered a thousand plastic buckets to entice people to get a shot, playing off a joke that Finns will line up for anything for a free bucket. 

Spain’s Travel Ban

Spain has effectively banned travelers from the UK who aren’t fully vaccinated. From Dec 1, it will only accept proof of vaccination for adult entry.

UK government advice also says that a certificate of recovery from COVID-19 isn’t accepted either by Spanish authorities.

Hungary’s Crackdown

The government in Budapest allows employers make vaccinations compulsory for staff in an effort to push people to get the shot. Anyone who doesn’t can be placed on unpaid leave.

Slovakia’s Cash

Slovakia’s Finance Minister Igor Matovic wants to give out vouchers worth 500 euros to everyone over the age of 60 who gets vaccinated, including those who have already received the shot. The vouchers, which could be used in restaurants and hotels, are opposed by some forces in government, but Matovic is hoping to push it through with the backing of some opposition lawmakers in parliament.
