Increased detection of proliferating, polyfunctional, HIV-1-specific T cells in DNA-modified vaccinia virus Ankara-vaccinated human volunteers by cultured IFN-gamma ELISPOT assay.

Induction of a long-term immunological memory, which can expand and defend the host upon pathogen encounter, is the "holy grail" of vaccinology. Here, using a sensitive cultured IFN-gamma ELISPOT assay, we show that 50% (15 out of 30) of healthy, HIV-1/2-uninfected volunteers who received pTHr.HIVA DNA prime-modified vaccinia virus Ankara.

Attitudes to using the laryngeal mask airway in paediatric resuscitation.

Aim: To explore nurses' attitudes towards, and confidence in, the use of laryngeal mask airway (LMA) and oral Guedel airway (OGA). The research formed part of a larger study which examined whether nurses could deliver adequate ventilation in children using these two airways compared to a consultant anaesthetist.

Method: Twenty five critical care nurses were trained to insert an LMA and an OGA.

Induction of multifunctional human immunodeficiency virus type 1 (HIV-1)-specific T cells capable of proliferation in healthy subjects by using a prime-boost regimen of DNA- and modified vaccinia virus Ankara-vectored vaccines expressing HIV-1 Gag coupled to CD8+ T-cell epitopes.

A double-blind randomized phase I trial was conducted in human immunodeficiency virus type 1 (HIV-1)-negative subjects receiving vaccines vectored by plasmid DNA and modified vaccinia virus Ankara (MVA) expressing HIV-1 p24/p17 gag linked to a string of CD8(+) T-cell epitopes. The trial had two groups. One group received either two doses of MVA.
