One of the world’s biggest medical companies says it has a coronavirus injection. Scientists at the companies Pfizer and BioNTech announced that they made a vaccine for the virus. They say it can prevent COVID-19 nine out of ten times, in people who haven’t been infected before.
The companies called the development “a great day for science and humanity.”
So, what now?
Pfizer will start to deliver the vaccines. Health experts say this will be the hardest part since storage and transport will be difficult. Pfizer’s vaccine needs a storage temperature of -94 degrees Fahrenheit.
