Health experts have cautioned that the amount of vaccine available for combating coronavirus or SARS-CoV-2 is likely to fall well short of global demand in the coming years , following an unprecedented effort to generate billions of doses.
Approximately 70 % of the world ‘s population-or 5.6 billion people-will probably have to be inoculated to start developing herd immunity and slowing its spread. Public health experts scenario most believe is a worldwide battle in which producers can only sell to the highest bidders, poorer countries struggling to purchase products, and nations where producers have placed stockpile vaccines for their own citizens.
International health advocates want to avoid a repeat of 2009, when wealthy countries — including the United States, led by former President Barack Obama were at the head of the line for H1N1 swine-flu vaccine, leaving underdeveloped countries with little supply until after the pandemic subsided. Such an approach will be sorely tested by current US President Trump and other world leaders with nationalistic impulses and their own anxious populations that want to reduce the deadly threat and bring their economies back to life.
In the United States, the federal government agency in charge of emergency vaccine development indicated it is prioritizing domestic concerns an “America First” mentality that has shaped much of the Trump administration’s pandemic response.
