This study developed a novel adjuvant candidate by combining liposome and QS-21 adjuvant, which can induce strong Th1 or Th17 cellular immunity and provide protection against pertussis. Results showed that the liposome + QS-21 adjuvant group had a rapid and higher antibody response, induced neutralizing antibodies, and recruited more IL-17A-secreting T-RM cells in mice, thus providing a key basis for developing an acellular pertussis vaccine.
The resurgence of pertussis in vaccinated communities may be related to the reduced long-term immunity induced by acellular pertussis vaccines. Therefore, developing improved pertussis vaccine candidates that could induce strong Th1 or Th17 cellular immunity is an urgent need. The use of new adjuvants may well meet this requirement. In this research, we developed a novel adjuvant candidate by combining liposome and QS-21 adjuvant. Adjuvant activity, protective efficacy, the level of neutralizing antibody against PT, and the resident memory T (T-RM) cells in lung tissue after vaccination were studied. We then performed B. pertussis respiratory challenge in mice after they received vaccination with traditional aluminum hydroxide and the novel adjuvant combination. Results showed that the liposome + QS-21 adjuvant group had a rapid antibody and higher antibody (PT, FHA, Fim) level, induced anti-PT neutralizing antibody and recruited more IL-17A-secreting CD4(+) T-RM cells along with IL-17A-secreting CD8(+) T-RM cells in mice, which provided robust protection against B. pertussis infection. These results provide a key basis for liposome + QS-21 adjuvant as a promising adjuvant candidate for developing an acellular pertussis vaccine that elicits protective immunity against pertussis.
