Common Cold is common among children aged 6 months to 5 years.
It is a viral infection which heals on its own.
There is no “cure”. There is no “vaccine.
The “Flu vaccine” does not prevent “recurrent cold and cough.
“Cold medications” are not recommended. Antibiotics should be avoided. Though the pharmacies are stocked full of various medications, none is effective. Giving these medications could lead to side effects.
A paediatrician could confirm a common cold and rule out pneumonia, ear infection or allergy. Then one could safely wait and let the “Cold” run its course.
