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.

How does an active immune system make colds worse? I would assume it makes them better since you’re less apt to get them.
I believe it’s due to the over reaction. There ends up being too much of an inflammation reaction. The symptoms become enhanced. A mild cough can become a heavy, nagging cough.
Most of the unpleasant symptoms you experience from respiratory viruses are your body responding to the infection. If that response is extreme and unchecked not only will the symptoms be far worse but they can become life threatening.
