As the World Health Organization met virtually on Monday for its first international summit since the coronavirus pandemic began, public health experts called for a firm stand against \u0022vaccine nationalism\u0022 in favor of a cooperative approach that would ensure equitable and universal access to the treatments created to battle the deadly outbreak.\u0026nbsp;At the summit, WHO is creating a list of \u0022priority recipients\u0022 for a vaccine, which is being researched by 130 organizations worldwide and which, in some cases, could be ready for initial\u0026nbsp;human trials\u0026nbsp;as early as July. Healthcare workers and elderly and immunocompromised people should have access to the vaccine first, WHO says, but the rule should apply to those in the country where the vaccine is discovered as well as internationally.\u0026nbsp;\u0022If we have vaccine nationalism, and one country looks after itself first, and at the expense of the rest of the world, everyone is going to continue to suffer,\u0022 Coalition\u0026nbsp;for Epidemic Preparedness Innovations chair Jane Halton told The Guardian.\u0022Now is the time for unity, for the international community to work together in solidarity to stop this virus and its shattering consequences. We cannot contemplate a future of fear and insecurity.\u0022 —António Guterres, U.N. Secretary-GeneralThe U.S. is among the countries experts have raised alarm over regarding the potential for a nationalistic response to the outbreak, as President Donald Trump declined to send representatives to last week\u0026#039;s summit hosted by the European Union, where dozens of countries joined with the Bill and Melinda Gates Foundation to pledge $8 billion to vaccine research efforts.\u0026nbsp;The president has claimed that he doesn\u0026#039;t care whether his task force, Operation Warp Speed, discovers a vaccine by the end of 2020 as it aims to, or if scientists in another country find a solution to the pandemic first—but his administration has indicated otherwise.\u0026nbsp;On March 30, Trump\u0026#039;s\u0026nbsp;Health and Human Services Department said in a statement that the administration\u0026#039;s primary goal is to make a\u0026nbsp;\u0022Covid-19 vaccine available for emergency use in the United States in early 2021.\u0022Pharmaceutical developers in the U.K. and India have also suggested they would prioritize making a vaccine available domestically first.Trump has repeatedly said that his response to the Covid-19 pandemic has been a \u0022great success\u0022 and that statements to the contrary are the result of partisanship, suggesting that the pandemic is a battle for his administration to win alone.\u0026nbsp;\u0022Do you believe that Trump\u0026#039;s base will be content with a vaccine strategy that does not \u0026#039;make America great again\u0026#039;?\u0022 David Salisbury, a former director of immunization for the British Department of Health, said to NBC News Monday. \u0022If your country develops the vaccine before anyone else, immediately exporting it to another country is not a vote-winner.\u0022Trump has also focused on placing blame for the pandemic on WHO and China, cutting funding for the global health organization and demanding an investigation into China\u0026#039;s response to the coronavirus.Chinese President Xi Jinping told the virtual WHO assembly on Monday that he also supports an investigation—after a vaccine is found and the pandemic is over.In an address to the assembly, United Nations Secretary-General António Guterres urged cooperation and solidarity among all countries to find a vaccine and said that research must take precedence over any questions regarding how the pandemic spread across the world.\u0022We are as strong as the weakest health systems,\u0022 Guterres said. \u0022Protecting the developing world is not a matter of charity or generosity but a question of enlightened self-interest. The global North cannot defeat COVID-19 unless the global South defeats it at the same time.\u0022\u0022Now is the time for unity, for the international community to work together in solidarity to stop this virus and its shattering consequences. We cannot contemplate a future of fear and insecurity,\u0022 he added. \u0022Either we get through this pandemic together, or we fail. Either we stand together, or we fall apart.\u0022In the U.K., Jeremy Farrar of the health research foundation Wellcome Trust joined the call for global cooperation, and said a failure to distribute a vaccine globally would leave the entire planet vulnerable once again to outbreaks.“The only exit strategy is\u0026nbsp;through science.”@JeremyFarrar, Director of the @WellcomeTrust, discusses a global response to the\u0026nbsp;#COVID19 crisis #WTISD https://t.co/7NKaASSQOo— OECD Better policies\u0026nbsp;for better lives (@OECD) May 18, 2020\u0026nbsp;\u0022A fragmented approach will not succeed in an interconnected world. It will only prolong the current situation, leading to a rolling cycle of lockdowns, limited travel and trade, and even more strain on our healthcare system,\u0022 said Farrar in an op-ed published in The Telegraph. \u0022Even if every person in the UK was vaccinated, epidemics in other countries would have a knock-on impact on our livelihoods and economy.\u0022\u0022No single country can do this alone,\u0022 he added.
