Annual flu vaccines are in a constant race against a rapidly mutating virus that may one day cause the next pandemic. A one-time vaccine protecting against all variants could give humanity a leg up.
An effective nasal vaccine could stop the virus that causes COVID-19 right at its point of entry. But devising one that works has been a challenge for researchers.
Using a Nobel Prize-winning technique called cryo-EM, researchers were able to identify potential areas on the hepatitis C virus that a vaccine could target.
The coronavirus vaccine was developed faster than any vaccine in history. It took just 332 days from the first sequencing of the virus genome to the first vaccines given to the public.
As most of the world early awaits a vaccine for COVID-19, a smaller group of people scoffs. They could spell real trouble in the effort to build widespread immunity.
Researchers around the world are working hard on developing a vaccine – but the process may still take 12-18 months. Here's why.
