Introduction: Pertussis vaccination in pregnancy is a safe and highly effective strategy to protect young infants against severe pertussis, but cases continue to occur. In November 2023, the authors of this paper met to discuss difficulties faced by pertussis vaccination programs in pregnant women in Europe, and the need and potential for new vaccines.
Areas Covered: We summarize current pertussis epidemiology, the status of pertussis vaccination in pregnancy in Europe, followed by a summary of the meeting on benefits of pertussis-only vaccines and pertussis vaccines with improved immunogenicity, including a review of available vaccines.
Expert Opinion: Ongoing surveillance and registers documenting vaccine uptake in pregnant women are important to monitor changes in pertussis epidemiology and estimated effectiveness of maternal pertussis vaccination programs in individual countries. While current programs have been effective, Tdap or Tdap-IPV combined vaccines are not the ideal choice but are the only vaccines available for pertussis immunization in pregnancy in Europe. Pertussis-only vaccine would avoid exposing women to unnecessary tetanus and diphtheria boosters in every pregnancy. Recombinant pertussis vaccines with higher immunogenicity could prolong passive immune protection against pertussis in young infants.

Pertussis resurged over the last decade in most countries that replaced the traditional whole-cell pertussis vaccines (wP) by the less reactogenic acellular pertussis vaccines (aP). The aP vaccines induce a Th2-polarized immune response and by a yet unknown mechanism hamper the clearance of from infected nasopharyngeal mucosa. The aP-induced pertussis toxin-neutralizing antibodies effectively prevent the life-threatening pertussis pneumonia in infants, but aP-elicited immunity fails to prevent infection of nasopharyngeal mucosa and transmission of .

Serological studies in infants can provide valuable information on the degree of protection conferred by IgG maternal passive transfer during early life. If infant levels are inadequate, protection may be incomplete, increasing the risk of life-threatening diseases such as pertussis and measles, before immunization completion. In addition, HIV infection, -highly prevalent in African countries like Malawi-may impair transplacental antibody transfer.

Background: A birth acellular pertussis vaccine may be a valuable alternative for immunity against infant pertussis when a pregnancy pertussis vaccine has not been administered. We assessed whether a birth dose may impair immunoglobulin G (IgG) responses to childhood pertussis boosters.
Methods: Children from our previous randomized controlled trial who received a monovalent 3-component aP and hepatitis B vaccine at birth (aP group) or hepatitis B only (control group) followed by Infanrix hexa at 2, 4 and 6 months of age were randomized to receive either high or low-dose diphtheria-tetanus acellular pertussis combination vaccine (DTPa-Infanrix/dTpa-Boostrix) at 18 months and 4 years of age.

Fever is not considered a typical presentation of pertussis. We characterized fever among 7840 pertussis cases from the Centers for Disease Control and Prevention's Enhanced Pertussis Surveillance with cough onset from 2015 to 2022. Ten percent of cases had a reported fever.

Background: Children worldwide can live lives free from various illnesses and disabilities due to vaccination. For instance, vaccination has eliminated smallpox, a deformative and frequently fatal illness that claimed an estimated 300 million lives in the twentieth century. However, due to a lack of access to immunization and other health services, 14.
