Dr. Judy Matta Pediatrics
Pertussis or whooping cough is treated with antibiotics, usually for 2 weeks. Treatment is most effective when it is given in the first stage of the illness before coughing spells begin. Although antibiotics can stop the spread of the whooping cough infection, they cannot prevent or treat the cough itself. Cough medications are not very effective.

Dr. Dina Helou Pediatrics
A child needs 2 doses of pertussis vaccine to be fully protected, so most probably your child got infected before receiving or even before having time to respond to the second dose.
Antibiotics are effective when given early in the course of the disease, they only decrease the duration of infectiousness and prevent spread.
Cough medication is not very effective in these cases.
Close follow up with your pediatrician is recommended.
You should also know that having pertussis does not confer long term immunity to your child and that he should still need to be vaccinated and receive booster doses of pertussis as recommended on the routine immunization schedule.
