As the Covid-19 pandemic unfolds, there is a lurking threat that we can no longer ignore: What happens if countries hoard or even nationalize vital resources to fight the disease? On March 2, according to the New York Times, the White House tried to persuade CureVac, a German company that is working on a Covid-19 vaccine, to move to the United States. A German newspaper claimed that the Trump administration wanted the U.S. to secure sole access to a vaccine, a claim the U.S. and the CureVac both denied. But the German government was rattled; its foreign minister, Heiko Maas, proclaimed that “we cannot allow a situation where others want to exclusively acquire the results of their research.” German Chancellor Angela Merkel met with senior German officials to discuss how to prevent the bid. A few days later, the Global Times, a newspaper owned by the Chinese Communist Party, published an editorial claiming that “the development of a vaccine is a battle that China cannot afford to lose,” arguing that China cannot rely on either Europe or the United States to give it access to a vaccine.
