Safety and efficacy of the ChAdOx1 nCoV-19 vaccine (AZD1222) against Sars-CoV-2
Background A safe and efficacious vaccine against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), if deployed with high coverage, could contribute to the control of the COVID-19 pandemic. We evaluated the safety and efficacy of the ChAdOx1 nCoV-19 vaccine in a pooled interim analysis of four trials. Methods This analysis includes data from four ongoing blinded, randomised, controlled trials done across the UK, Brazil, and South Afri…
Human population dynamics
Time-series analysis of parish register series can be used to study human population dynamics at three different levels: (i) The metapopulation of preindustrial rural England. A short wavelength, exogenous oscillation in the burials series of 404 parishes can be detected which, it is suggested, was driven by a cycle of malnutrition associated with wheat prices. (ii) Individual populations, where long-term endogenous oscillations in baptisms and b…
Interacting effects of nutrition and social class differentials on fertility and infant mortality in a pre-industrial population
Inadequate nutrition of both the mother and her offspring at each stage of its development - before pregnancy, in the womb, in infancy and during early childhod - played an important role in the patterns of subfertility and infant mortality in a saturated, marginal, preindustrial community. It is suggested that the three social classes had different diets but all were deficient in some essential constituents. Differences in nursing practices in t…
Nutrition, Fertility and Steady-State Population Dynamics in a Pre-Industrial Community in Penrith, Northern England
The effect of nutrition on fertility and its contribution thereby to population dynamics are assessed in three social groups (elite, tradesmen and subsistence) in a marginal, pre-industrial population in northern England. This community was particularly susceptible to fluctuations in the price of grains, which formed their basic foodstuff. The subsistence class, who formed the largest part of the population, had low levels of fertility and small …

The Interacting Effects of Prices and Weather on Population Cycles in a Preindustrial Community
The exogenous cycles and population dynamics of the community at Penrith, Cumbria, England, have been studied (1557-1812) using aggregative analysis, family reconstitution and time series analysis. This community was living under marginal conditions for the first 200 years and the evidence presented is of a homeostatic regime where famine, malnutrition and epidemic disease acted to regulate the balance between resources and population size. This …
Human Demography and Disease
Human Demography and Disease offers an interdisciplinary and integrated perspective on the relationship between historical populations and the dynamics of epidemiological processes. It brings the techniques of time-series analysis and computer matrix modelling to historical demography and geography to extract detailed information concerning the oscillations in births, deaths, migrations and epidemics from parish registers and other data series an…

Interacting Factors Affecting Illegitimacy in Preindustrial Northern England
Illegitimacy in a historic, single community at Penrith, Cumbria (1557–1812), has been studied using aggregative analysis, family reconstitution and time series analysis. This population was living under extreme conditions of hardship. Long, medium and short wavelength cycles in the rate of illegitimacy have been identified by time series analysis; each represents a different response to social and economic pressures. In a complex interaction of …
Victimisation beyond the metropolis
Victimisation surveys have revealed that high crime rate areas not only have a high rate of victim prevalence, but that a small proportion of the victims may experience more than half of the crime reported. This paper examines how the prevalence and concentration of victimisation influence the incidence rate in a low crime rate area
The plague in Penrith, Cumbria, 1597/8
Using a family reconstitution study the biology of the plague in Penrith, Cumbria in 1597/8 is described in detail; it was an explosive epidemic that spread rapidly within families and 606 individuals died of the plague, some 40% of the population. The age-specific mortality corresponded with the calculated age structure of the population and infection appeared to be random. The sex ratio of victims was 1.37 females to 1 male. The plague spread f…
Infant mortality and famine
OBJECTIVE--To examine whether periodic variations in annual infant mortality were associated with malnutrition and the poor quality of the food supply available to the community. DESIGN--Retrospective study of historical epidemiology of infant mortality by time series analysis and family reconstitution of parish registers of burials and baptisms. SETTING--Penrith, Cumbria, England, 1557-1812. SUBJECTS--A total of 17,500 births during 1557-1812. R…
Smallpox Epidemics in Cities in Britain
and was greatly feared from the time of the final visitation of bubonic plague in I666 until the end of the nineteenth century, when it ceased to be endemic in England. Relatively rare as a fatal disease in England until the I630s, after I666 it replaced plague as the most feared of diseases. Many accounts suggest that a particularly virulent strain began to afflict people of all ages in the middle and later decades of the seventeenth century, an…
The dynamics of smallpox epidemics in Britain, 1550–1800
Time-series analysis, a valuable tool in studying population dynamics, has been used to determine the periodicity of smallpox epidemics during the seventeenth and eighteenth centuries in two contrasting representative situations: 1) London, a large city where smallpox was endemic, and 2) Penrith, a small rural town. The interepidemic period was found to be two years in London and five years in Penrith. Equations governing the dynamics of epidemic…
