EV71 infection has become a serious public health threat especially among young children. Yet, at present, no specific antiviral drug against EV71 infection is available. A number of scientists are studying various kinds of vaccines, including inactivated vaccine, virus-like particle vaccine, DNA vaccine, synthetic peptide vaccines, and transgenic oral vaccine. This article reviews the recent advancement in the design of various kinds of vaccine against EV71 as well as their prospective usefulness, effectiveness, weakness and developments in the foreground.

Numerous studies have indicated that human metapneumovirus (hMPV) is an important viral pathogen in acute respiratory infections in children, presenting similar manifestations with respiratory syncytial virus (RSV). HMPV infection peaks in the winter-spring season and is more prevalent in younger ages, especially in children less than 1 year old. Host innate immune response has been implicated in recognition of pathogen-associated molecular patterns (PAMPs) of the virus. This recognition occurs through host pattern recognition receptors (PRRs). Toll like receptors (TLRs) are one of the largest class of PRRs which initiate and regulate adaptive immune responses. Some studies have indicated that TLR 3 and TLR 4 may play critical roles in hMPV infection. Construction of recombinant mutant viruses lacking one or two N-linked glycosylation sites in the F protein by using site-directed mutagenesis and reverse genetics may be helpful for developing attenuated live vaccines.

Despite recent significant advances in the treatment of hematological malignancies, relapse of this disease is of great note with the existence of the minimal residual disease (MRD). Tumour peptide vaccine seems to be one of the effective immunotherapies for eliminating tumor cells of MRD. This review focuses on the late results of clinical trails of peptide vaccination protocols targeting WT1, RHAMM, BCR-ABL, PR1 in hematological malignancies and the development of specific immune responses to PRAME and Survivin peptides. An outlook to heteroclitic peptides, new adjuvants, combined peptide vaccines and Ad-tWT1 vaccine is also given to further explore the possibility to enhance the efficacy of the peptide vaccine.

Influenza, caused by influenza virus, is a serious respiratory illness which poses a global public health threat. Vaccination is the primary strategy for the prevention and control of influenza. Although both inactivated vaccines and the live attenuated vaccines are effective in preventing influenza, the current vaccines have poor efficacy in the elderly and fail to provide protection against heterosubtype viruses. Development of a safer and more effective influenza vaccine that provides broad cross protection, overcoming the intrinsic limitation of the current vaccines, has been a scientific challenge. During the past decades, structural biology, reverse genetic and other virological technologies developed quickly and sped the progress of influenza vaccinology. Some new strategies for developing influenza vaccine have been generated, produced encouraging results, which showed great prospect as next-generation of influenza vaccines.

The evaluation methods of immune persistence include direct evaluation, indirect evaluation, model prediction, and meta-analysis and so on. Direct evaluation is the gold standard for evaluating the immune persistence of vaccines by quantifying the protective effect of vaccines on the onset and (or) infection of preventable diseases. Indirect evaluation of immune persistence by immunological surrogate indicators is more widely used in practice. In addition, mathematical models and meta-analysis can also be used to evaluate the immune persistence of vaccines. It is of great significance to select the appropriate evaluation method to analyze the immune persistence of the vaccine according to the specific situation.

Classical swine fever (CSF), an acute and highly contagious disease of swine, is caused by classical swine fever virus. CSF is one of the most devastating diseases to the pig industry worldwide and results in serious economic losses. Currently prophylactic vaccination is still an important strategy for the control of CSF. Live attenuated vaccines (such as C-strain) are safe and effective. However, there are significant changes in the clinical features of CSF, displaying concurrent typical and atypical CSF, and simultaneous inapparent and persistent infections. Immunization failure has been reported frequently and it is difficult to distinguish between wild-type infected and vaccinated animals (DIVA). So there is an urgent need to develop more effective and safer DIVA or marker vaccines for the control of CSF. In this review, some of the most recent advances in new-type vaccines against CSF, including DNA vaccines, live virus-vectored vaccines, protein or peptide-based vaccines, gene-deleted vaccines and chimeric pestivirus-based vaccines, are reviewed and discussed.
