A phase 3 randomized, open-label study evaluating the immunogenicity and safety of concomitant and staggered administration of a live, pentavalent rotavirus vaccine and an inactivated poliomyelitis vaccine in healthy infants in China.
This open-label, randomized, phase 3 study in China (V260-074; NCT04481191) evaluated the immunogenicity and safety of concomitant and staggered administration of three doses of an oral, live, pentavalent rotavirus vaccine (RV5) and three doses of an intramuscular, inactivated poliomyelitis vaccine (IPV) in 400 healthy infants. The primary objective was the non-inferiority of neutralizing antibody (nAb) responses in the concomitant- versus the staggered-use groups. Antibody responses were measured at baseline and 1-month post-dose 3 (PD3). Parents/legal guardians recorded adverse events for 30 or 15 d after study vaccinations in the concomitant-use or staggered-use groups, respectively. At PD3, >98% of participants seroconverted to all three poliovirus types, and the primary objective was met as lower bounds of the two-sided 95% CI for between-group difference in nAb seroconversion percentages ranged from - 4.3% to - 1.6%, for all poliovirus types, p < .001. At PD3, geometric mean titers (GMTs) of nAb responses to poliovirus types 1, 2, and 3 in the concomitant-use group and the staggered-use group were comparable; 100% of participants had nAb titers ≥1:8 and ≥1:64 for all poliovirus types. Anti-rotavirus serotype-specific IgA GMTs and participants with ≥3-fold rise in postvaccination titers from baseline were comparable between groups. Administration of RV5 and IPV was well tolerated with comparable safety profiles in both groups. The immunogenicity of IPV in the concomitant-use group was non-inferior to the staggered-use group and RV5 was immunogenic in both groups. No safety concerns were identified. These data support the concomitant use of RV5 and IPV in healthy Chinese infants.

(formerly Human Vaccines; issn 1554-8619)
Vaccine research and development is extending its reach beyond the prevention of bacterial or viral diseases. There are experimental vaccines for immunotherapeutic purposes and for applications outside of infectious diseases, in diverse fields such as cancer, autoimmunity, allergy, Alzheimer’s and addiction. Many of these vaccines and immunotherapeutics should become available in the next two decades, with consequent benefit for human health. Continued advancement in this field will benefit from a forum that can (A) help to promote interest by keeping investigators updated, and (B) enable an exchange of ideas regarding the latest progress in the many topics pertaining to vaccines and immunotherapeutics.
Human Vaccines & Immunotherapeutics provides such a forum. It is published monthly in a format that is accessible to a wide international audience in the academic, industrial and public sectors.
