I can elaborate on that, which also includes the situation in Hong Kong.
China has pursued a policy of zero COVID cases. From the start the Chinese policy was they're not going to let it in; they're going to focus on the testing. As soon as there was a case, they kept it isolated and took it out of society, basically. It's come down to this omicron variant for them to realize this policy is not sustainable.
In terms of hesitancy, I want to bring up one recent study by the Partnership for Evidence-Based Response to COVID-19. It showed that an overwhelming majority of people in Africa, 78% of people surveyed across 19 countries, are willing to get vaccinated.
Hesitancy is not particularly higher in developing countries than in developed countries. People want to get vaccinated everywhere, but having this charitable approach whereby countries never know when they're going to get vaccines and how soon they're going to expire makes it very difficult to get these vaccines into people's arms.
