Evaluation in Mouse Model of Combined Virus-bacterial Vaccine Based on Attenuated Influenza A(H7N3) Virus and the Group B Streptococcus Recombinant Polypeptides.
Article in The open microbiology journal, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundSecondary bacterial influenza complications are a common cause of excesses morbidity and mortality, which determines the need to develop means for specific prophylaxis. Group B streptococcal infection is especially common cause of pneumonia among children and the elderly with underlying conditions. Here we investigate in a mouse model the effects of combined intranasal immunization using live attenuated influenza vaccine and recombinant polypeptides based on group B
methodsGroups of outbred mice received two doses of the following preparations: 1) the reassortant A/17/Mallard/Netherlands/00/95 (H7N3) influenza virus; 2) a mixture of P6, ScaAB, ScpB1 and Stv recombinant GBS proteins (20 µg total); 3) the A(H7N3) influenza vaccine pooled with the four bacterial peptide preparation; 4) control animals were treated with PBS.
resultsIntranasal vaccination using LAIV in combination with GBS polypeptides provided advantageous protection against infections with homologous A/Mallard/Netherlands/12/00 (H7N3) wild type virus or heterologous A/Puerto Rico/8/34 (H1N1) followed by serotype II GBS infection. Also, combined vaccination improved bacterial clearance from the lungs of mice.
conclusionIntranasal immunization with LAIV+GBSV was safe and enabled to induce the antibody response to each of vaccine components. Thus, the combined vaccine increased the protective effect against influenza and its bacterial complications in mice compared to LAIV-only.
