This article shows how the elite origins and religious mission of the Regent Street Polytechnic encouraged participation in amateur sport in London, and promoted the suburb of Chiswick as a global context for competitive sports. From the 1880s to the outbreak of World War 2, the Polytechnic and its facilities forged synergies between the city centre and the burgeoning suburbs in London, engendering a city-wide culture of amateur sports, and embedding the Polytechnic into a global network of athletes. Suburbs are typically presented by writers as being ‘on the edge’ of metropolitan life, but such perspectives are wrong. The West London suburb of Chiswick was the home of Polytechnic facilities that provided a dynamic context for the internationalization and modernization of sport in the capital.

In 1915 plans for the celebration of the 700th anniversary of Magna Carta had to be dropped following the outbreak of the First World War. Such celebrations marked a sense of Magna Carta as an event in the history of these islands. The usage of the term Magna Carta in Parliament in the run-up to the First World War, however, shows that its granting was not seen only as a significant historical event to be memorialised. During the period from 1900, opening with war in South Africa and ending in 1914 with war throughout Europe, the Great Charter was mentioned 85 times in Parliament. As a period marked by a lengthy constitutional crisis in 1909-11 and beset with problems in Ireland and the Empire, this seems like a good case study period to choose. This short paper attempts to analyse how and why it was invoked in Parliament in the years and what these various usages tell us about how Magna Carta was understood at the time.

BACKGROUND The West African outbreak of Ebola virus disease that peaked in 2014 has caused more than 11,000 deaths. The development of an effective Ebola vaccine is a priority for control of a future outbreak. METHODS In this phase 1 study, we administered a single dose of the chimpanzee adenovirus 3 (ChAd3) vaccine encoding the surface glycoprotein of Zaire ebolavirus (ZEBOV) to 60 healthy adult volunteers in Oxford, United Kingdom. The vaccine was administered in three dose levels — 1×1010 viral particles, 2.5×1010 viral particles, and 5×1010 viral particles — with 20 participants in each group. We then assessed the effect of adding a booster dose of a modified vaccinia Ankara (MVA) strain, encoding the same Ebola virus glyco- protein, in 30 of the 60 participants and evaluated a reduced prime–boost interval in another 16 participants. We also compared antibody responses to inactivated whole Ebola virus virions and neutralizing antibody activity with those observed in phase 1 studies of a recombinant vesicular stomatitis virus–based vaccine expressing a ZEBOV glycoprotein (rVSV-ZEBOV) to determine relative potency and assess durability. RESULTS No safety concerns were identified at any of the dose levels studied. Four weeks after immunization with the ChAd3 vaccine, ZEBOV-specific antibody responses were similar to those induced by rVSV-ZEBOV vaccination, with a geometric mean titer of 752 and 921, respectively. ZEBOV neutralization activity was also similar with the two vaccines (geo- metric mean titer, 14.9 and 22.2, respectively). Boosting with the MVA vector increased virus-specific antibodies by a factor of 12 (geometric mean titer, 9007) and increased glycoprotein-specific CD8+ T cells by a factor of 5. Significant increases in neutralizing antibodies were seen after boosting in all 30 participants (geometric mean titer, 139; P<0.001). Virus-specific antibody responses in participants primed with ChAd3 remained positive 6 months after vaccination (geometric mean titer, 758) but were significantly higher in those who had received the MVA booster (geometric mean titer, 1750; P<0.001). CONCLUSIONS The ChAd3 vaccine boosted with MVA elicited B-cell and T-cell immune responses to ZEBOV that were superior to those induced by the ChAd3 vaccine alone.
