| Open AccessTranscriptional specialization of human dendritic cell subsets in response to microbial vaccines
The effects of vaccines on human dendritic cells (DCs) are incompletely understood. Here the authors build a transcriptional modular network based on in vitroinfection of human DCs and apply it for the characterization of the DC response to 13 different vaccines.

A micro-sterile inflammation array as an adjuvant for influenza vaccines
There is a need of improved adjuvants for influenza vaccines. Here, the authors describe an adjuvant strategy using micro-fractional laser treatment combined with a topical cream containing a TLR 7 ligand that can enhance the immune response to intradermal vaccination with transient, constrained local inflammation.

Antigen capture and archiving by lymphatic endothelial cells following vaccination or viral infection
Viral antigens can persist within the secondary lymphoid tissues of the host for many weeks after resolution of the infection. Tamburini et al.demonstrate that antigens remaining following viral infection or vaccination can be captured and maintained for extended periods of time by lymphatic endothelial cells.

Receptor mimicry by antibody F045–092 facilitates universal binding to the H3 subtype of influenza virus
Influenza A H3 viruses circulate in humans and bind host cells using the haemagglutinin (HA) glycoprotein. Here, Lee et al.perform a structural analysis of antibody F045–092 with broadly neutralizing activity against the H3 subtype and reveal its interaction with the HA receptor binding site.

Engineering the type III secretion system in non-replicating bacterial minicells for antigen delivery
Bacterial type III secretion systems (T3SS) improve the delivery of vaccine antigens and antigen-specific immune responses but require the use of live vaccines. Carleton et al. report the assembly of a functional T3SS in replication-incompetent bacterial minicells that can deliver vaccine antigens in vitro and in vivo.

Mapping of H3N2 influenza antigenic evolution in China reveals a strategy for vaccine strain recommendation
Influenza vaccines are updated frequently to accommodate changing influenza antigenicity. Here, the authors develop a new computational method for predicting the antigenicity of H3N2 influenza strains based on the HA sequence.

| Open AccessPandemic 2009 H1N1 vaccine protects against 1918 Spanish influenza virus
Vaccination against one viral strain can result in cross-reactive antibodies against another viral strain. In this study, the vaccination of mice against the 2009 H1N1 virus is shown to protect mice from the 1918 Spanish influenza virus, which resulted in millions of deaths worldwide.
