Even finding a covid-19 vaccine won't be enough to end the pandemic
Johnson & Johnson’s race to manufacture a billion doses of coronavirus vaccine is ramping up in a small biotechnology plant near Interstate 95 in Baltimore. But even as technicians prepare to lower 1,000-liter plastic bags of ingredients into steel tanks for brewing the first batches of experimental vaccine, international concern is bubbling about what countries will get the first inoculations.
The Baltimore plant is the second of four planned locations around the world where Johnson & Johnson plans to pump out vaccine on a massive scale, months before testing the first dose in a human being. The manufacturing head start is one part of a worldwide scramble to protect the human population from the virus, which is not expected to vanish on its own.
If SARS-CoV-2 establishes itself as a stubborn, endemic virus akin to influenza, medical experts say, there almost certainly will not be enough vaccine for at least several years, even with the unprecedented effort to manufacture billions of doses. About 70 percent of the world’s population — or 5.6 billion people — will probably need to be inoculated to begin to establish herd immunity and slow its spread, scientists say.
