Single vaccine could protect against all coughs, colds and flus,
researchers say
A single nasal spray vaccine could protect against all coughs, colds
and flus, as well as bacterial lung infections, and may even ease
allergies, say US researchers.
The team at Stanford University have tested their "universal vaccine"
in animals and still need to do human clinical trials.

The approach described in the journal Science does not train the
immune system. Instead it mimics the way immune cells communicate with
each other.
It is given as a nasal spray and leaves white blood cells in our lungs
- called macrophages - on "amber alert" and ready to jump into action
no matter what infection tries to get in.
The effect lasted for around three months in animal experiments.
