BACKGROUND Economic assessments that guide policy making on immunizations are becoming increasingly important in light of new and anticipated vaccines for adolescents. However, important considerations that limit the utility of these assessments, such as the diversity of approaches used, are often overlooked and should be better understood. OBJECTIVE Our goal was to examine economic studies o...

Gene-based vaccines as typified by plasmid DNA vaccines and recombinant viral-vectored vaccines are expected as promising solutions against infectious diseases for which no effective prophylactic vaccines exist such as HIV, dengue virus, Ebola virus and malaria, and for which more improved vaccines are needed such as tuberculosis and influenza virus. Although many preclinical and clinical trial...

BACKGROUND We aimed to assess evidence of efficacy and effectiveness of live attenuated and inactivated influenza vaccines in children up to 16 years of age. METHODS We searched the Cochrane Library, MEDLINE, EMBASE Biological Abstracts, and Science Citation Index to June, 2004, in any language, and contacted vaccine manufacturers and authors of relevant studies to identify additional data. W...

Increasing evidence that the currently available acellular pertussis vaccines are not providing optimal control of pertussis in the United States and many other countries has stimulated interest in improvements of the current vaccines and in the development of new vaccines. A better understanding of the limitations of the current vaccines and the basis for the pertussis resurgence is needed to ...

Developing effective tuberculosis (TB) vaccines is a high priority. We use mathematical models to predict the potential public health impact of new TB vaccines in high-incidence countries. We show that preexposure vaccines would be almost twice as effective as postexposure vaccines in reducing the number of new infections. Postexposure vaccines would initially have a substantially greater impac...

Ongoing research into the use of messenger RNA (mRNA) vaccines for treatment cancer has been expediated by coronavirus pandemic because similar technology was used in development mRNA COVID‐19 vaccines. So how close are we now to widespread clinical anti‐cancer vaccines?

Background: Vaccines capable of controlling tumor virus based infections are found difficult to develop due to the consistence latent infection in the host. DNA vaccines are attractive tools for the development of HPV vaccines and inducing antigen-specific immunity owing to the stability, simplicity of delivery, safety and cost effectiveness. However, there is a need to increase their potency b...

Cancer related deaths have shown a progressive increase over the past decade and the newer cases of cancers are estimated to rise in 2030. The current treatment modalities available for cancer are highly toxic, impair quality of life and develop resistance with course of time. Thus, there is a growing necessity for the prevention and cure of cancer related morbidity and mortality. One of the pr...
