Summary of "Use of Adeno-associated viral vectors to improve delivery of a DNA vaccine against dengue virus."

Dengue virus (DENV) remains a significant healthcare and socioeconomic burden for endemic countries. Attempts to produce a safe and effective vaccine have been unsuccessful so far, making this task one of the top priorities in the field. We have previously shown that an EDIII-based DNA vaccine is able to induce neutralizing, long-lasting and highly specific antibody responses for all four DENV serotypes in mice using gene-gun delivery technology. Here, we describe the use of recombinant Adeno-associated viral vectors as an alternative DNA delivery platform, in combination with different immunization schedules, to simplify the vaccination protocol without compromising the induction of neutralizing antibody responses. Our results demonstrate that using viral vectored-platforms to deliver genetic vaccines could potentially reduce the number of doses required to induce a sustained DENV-neutralizing response, thus facilitating the implementation and deployment of the vaccine in developing countries.

Medical and Biotech [MESH] Definitions

Any vaccine raised against any virus or viral derivative that causes hepatitis.

A combined vaccine used to prevent infection with diphtheria and tetanus toxoid. This is used in place of DTP vaccine (DIPHTHERIA-TETANUS-PERTUSSIS VACCINE) when PERTUSSIS VACCINE is contraindicated.

Forms to which substances are incorporated to improve the delivery and the effectiveness of drugs. Drug carriers are used in drug-delivery systems such as the controlled-release technology to prolong in vivo drug actions, decrease drug metabolism, and reduce drug toxicity. Carriers are also used in designs to increase the effectiveness of drug delivery to the target sites of pharmacological actions. Liposomes, albumin microspheres, soluble synthetic polymers, DNA complexes, protein-drug conjugates, and carrier erythrocytes among others have been employed as biodegradable drug carriers.

A live vaccine containing attenuated poliovirus, types I, II, and III, grown in monkey kidney cell tissue culture, used for routine immunization of children against polio. This vaccine induces long-lasting intestinal and humoral immunity. Killed vaccine induces only humoral immunity. Oral poliovirus vaccine should not be administered to immunocompromised individuals or their household contacts. (Dorland, 28th ed)

A bacterial vaccine for the prevention of brucellosis in man and animal. Brucella abortus vaccine is used for the immunization of cattle, sheep, and goats.
