RÉSUMÉ
Due to the tumor malignancy or immunosuppressive treatment, patients with cancer in general are more susceptible to vaccine-preventable infections. The types, timing, dose of vaccination or even the immunization program for them may differ from those for the normal persons. At present, it is recommended to use inactivated vaccines for patients with cancer rather than attenuated live vaccines, Vaccinations should be avoided during immunosuppressive therapy; patients with cancer should receive double dosage of hepatitis B vaccines and two doses of inactivated influenza vaccines yearly. This paper summarizes the progress in clinical trials of vaccination for cancer patients in foreign countries, and provide reference for the development and implementation of vaccination strategy for cancer patients in China.

The importance of vaccine on public health is related to the herd protection related to the levels of vaccine coverage, which directly influences the vaccinated individuals as well as the unvaccinated community. Reaching the level of herd protection by increasing vaccine coverage is the basic strategy to eradicate related infectious diseases. Again, herd protection has played an important role in public health practices. With the increasing interests in estimating the vaccine herd protection, we however, have seen only few relevant papers including observational population-based and cluster-randomized clinical trials reported in China. We hope to discuss the study designs for evaluating the vaccine herd protection in order to generate evidence-based related research in this field.

Genes play an important role in the immune system response, and different gene loci may result in different vaccine immune response rates. This review focuses on the correlation between gene polymorphisms and vaccine immune response in order to investigate the influence of gene polymorphisms on the immune response to vaccines. It discusses the effect of an individual's immune response after vaccination at genetic level and provides a scientific basis for individualized immune development strategies. It reveals that human leukocyte antigen genes, various cytokines and their receptor genes, and Toll-like receptor genes all affect the vaccine immune response.
