background hypervariability of hcv proteins is an important obstacle to design an efficient vaccine for hcv infection. multi-epitope vaccines containing conserved epitopes of the virus could be a promising approach for protection against hcv. objectives cellular and humoral immune responses against multi-epitope dna and peptide vaccines were evaluated in balb/c mice. materials and methods in th...

poliomyelitis, an acute viral infectious disease caused by poliovirus, still remains a public health problem in developing countries. despite the global effort to eradicate polio, continuing the polio immunization with a potent and safe vaccine is essential. for accurate vaccine evaluation, three types of cell lines including hela, hep2c and vero were evaluated and compared using two methods of...

Therapeutic vaccines are different from the well-known prophylactic vaccines in that they are designed to treat patients already suffering from a disease instead of preventing the disease in healthy individuals. Several therapeutic vaccines are today in late-stage clinical development for non-small-cell lung cancer. These vaccines use different approaches including peptides, cell lines and vira...

OBJECTIVE To assess the efficacy and safety of whole-cell and acellular pertussis vaccines administered to children singly or within diphtheria, tetanus and pertussis (DTP) vaccines. DATA SOURCES We searched the Cochrane Library, MEDLINE, EMBASE, Biological Abstracts and Science Citation Index to December 2001. Specialised websites and bibliographies of retrieved articles and reviews were ass...

The recognition that the development of cancer is associated with acquired immunodeficiency, mostly against cancer cells themselves, and understanding pathways inducing this immunosuppression, has led to a tremendous development of new immunological approaches, both vaccines and drugs, which overcome this inhibition. Both "passive" (e.g. strategies relying on the administration of specific T ce...
