Vaccination is often combined with an injection. It can also take the form of a nasal spray: an approach that is still rare, but which could be effective against Covid. Here’s why.
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.
