Pertussis vaccine Pertussis vaccine Pertussis vaccine is a vaccine that protects against whooping cough (pertussis). There are two main types: whole-cell vaccines and acellular vaccines. The whole-cell vaccine is about 78% effective while the acellular vaccine is 71–85% effective. The effectiveness of the vaccines appears to decrease by between 2 and 10% per year after vaccination with a more rapid decrease with the acellular vaccines. Vaccinating the mother during pregnancy may protect the baby. The vaccine is estimated to have saved over 500,000 lives in 2002. The World Health Organization and Center for Disease Control and Prevention recommend all children be vaccinated
