Subjects receiving the same vaccine often show different levels of immune responses and some may even present adverse side effects to the vaccine. Systems vaccinology can combine omics data and machine learning techniques to obtain highly predictive signatures of vaccine immunogenicity and reactogenicity. Currently, several machine learning methods are already available to researchers with no background in bioinformatics. Here we described the four main steps to discover markers of vaccine immunogenicity and reactogenicity: (1) Preparing the data; (2) Selecting the vaccinees and relevant genes; (3) Choosing the algorithm; (4) Blind testing your model. With the increasing number of Systems Vaccinology datasets being generated, we expect that the accuracy and robustness of signatures of vaccine reactogenicity and immunogenicity will significantly improve.

Introduction: Immunocompromised persons have high risk of persistent human papillomavirus (HPV) infection and HPV-related diseases, and lower immune response to vaccines. This study evaluated the immunogenicity and safety of administering a fourth dose of quadrivalent (4v)HPV vaccine in immunosuppressed women who did not seroconvert after three doses.

Methods: An open-label, not-controlled trial included immunosuppressed women (solid organ transplant patients and women receiving treatment for SLE) who did not seroconvert to at least one of the four HPV vaccine types after three 4vHPV vaccine doses.

Introduction: Porcine reproductive and respiratory syndrome virus (PRRSV) causes reproductive and respiratory diseases in sow herds and piglets. The emergence of ORF5 RFLP 1-7-4-like (NADC34-like) PRRSV strain in China has brought a new round of challenges to PRRSV prevention.

Methods: In addition, recombinant adenovirus vaccine candidates against the newly emerged NADC34-like strain were constructed in the study; the immunogenicity of the vaccine was investigated in piglets.

Background: In endemic COVID-19, immunocompromised children are vulnerable until vaccinated but the optimal primary vaccination regime and need for booster doses remains uncertain.

Methods: We recruited 19 immunocompromised children (post-solid organ transplantation, have autoimmune disease or were on current or recent chemotherapy for acute lymphoblastic leukemia), and followed them from the start of primary vaccination with BNT162b2 mRNA SARS-CoV-2 until 1-year post-vaccination. We investigated the quality of vaccine immunogenicity, and longevity of hybrid immunity, in comparison to healthy children.

Self-amplifying RNA (saRNA) vectors are a next-generation RNA technology that extends the expression of heterologous genes. Clinical trials have shown the dose-sparing capacity of saRNA vectors in a vaccine context compared to conventional messenger RNA. However, saRNA vectors have historically been based on a limited number of alphaviruses, and only the Venezuelan equine encephalitis virus-based saRNA vaccines have been used clinically.

Rabies is a lethal zoonotic infectious disease. Vaccines against the rabies virus have significantly reduced the number of deaths from the disease. However, all the licensed rabies vaccines are inactivated vaccines, which have limited immunogenicity and complicated immunization procedures.
