PHILADELPHIA — Her gloved fingers working quickly yet carefully, Garima Dwivedi filled row after row of little wells on a plastic laboratory plate, pushing a button to squirt drops of clear fluid she had extracted from the blood of mice.
The mice had been vaccinated against a coronavirus infection. Like so many other scientists throughout the COVID-19 pandemic, Dwivedi wanted to see if the animals had responded by making antibodies.
But not just for this coronavirus. This new vaccine, in the University of Pennsylvania lab of Drew Weissman, is designed to protect the world against multiple coronaviruses — including those we don’t know about yet.
