What are you talking about? It is not the responsibility of the WHO to create vaccines. Only the pharmaceutical companies such as Pfizer and AstraZeneca can do that. What the WHO can do is to make sure that effective vaccines reach all the counties, so that there is no severe shortage of the medication. Companies in certain sectors (hotels, aviation, tourism.etc) have gone bankrupt, and there is not much we can do about it. Full economic recovery will occur only when the pandemic is contained. And unfortunately, that is at least 6-7 months away.
Could've prevented the economic distress if the government of some countries followed a strict guidelines and did the necessary preventions to stop the entry of the virus in the first place. One example is my country, the virus has been ravaging China already but they didn't seem to care about the people and that they felt that it's offensive to China to close our borders and now here we are celebrating two years of lockdown.
