Pertussis: No, this is not common, but no vaccine is 100% effective. In general, dtap vaccines are 80-90% effective. Among kids who get all 5 doses of dtap on schedule, effectiveness is very high within the year following the 5th dose – at least 9 out of 10 kids are fully protected from diphtheria, tetanus and pertussis (whooping cough).

It happens,: Because these children are not completely vaccinated. It takes 5 doses of vaccine over time for maximal protection. If they are exposed before they are fully protected, then yes they can still get pertussis even if they have had a few doses of the vaccine.
