Highly published and cited academic. Professor of Risk Information Management, Queen Mary London UniversitySpecialist in risk management for critical systems. Expert in quantitative risk assessment and predicting the probabilities of unknown eventsImplications of the Office for National Statistics estimates of Covid-19 vaccine take up in England on the representativeness of its sample populationhttps://www.researchgate.net/publication/364310694_Implications_of_the_Office_for_National_Statistics_estimates_of_Covid-19_vaccine_take_up_in_England_on_the_representativeness_of_its_sample_population?channel=doi&linkId=63459d419cb4fe44f31d90fd&showFulltext=trueIs it important to collect quantitively data to learn about a population group?Why do we need a representative sample of a population to collect valid data for the population as a whole?Can you give an example of how a representative sample of a population should be selected?Which sample is used by the ONS to generate their estimates of covid vaccine take up?Is this then a skewed sample?Given that to be included an individual had to have been in the 2011 census and must currently be registered with a GP, how many people are missed out?Of these 8 million people that are missed out from the ONS data, what proportion of these are unvaccinated?Are there any other estimates of the proportion of the population vaccinated for comparative purposes?Does this mean that the sample is not as representative as would be ideal?If the sample is not representative, how does this effect the validity of their data and hence their conclusions?

Evidence for non-pharmaceutical interventions such as mass lockdowns was weak. (Not that you could have guessed that easily at the time from government messaging).Uploaded 02-10-23Research and analysisCOVID-19: non-pharmaceutical interventions to reduce transmissionhttps://www.gov.uk/government/publications/covid-19-non-pharmaceutical-interventions-to-reduce-transmission28 September 2023Identify and categorise primary studies that reported on the effectiveness of non-pharmaceutical interventions (NPIs),implemented in community settings to reduce the transmission of coronavirus (COVID-19) in the UK. Physical distancingSurface cleaningFace coveringsHand and respiratory hygieneVentilationMeasures to identify and isolate those who are infectious or may become infectious, such as testing and isolation (also known as quarantine) Measures to reduce the number of contacts, including lockdown, settings closures and limitation of social contacts (such as the ‘rule of 6’) Shielding of the most clinically vulnerable Travel and border restrictionsReview includes 151 studies (search date: 1 March 2023)Evidence gap map for NPIshttps://research.ukhsa.gov.uk/evidence-gap-map-npi-and-covid-19/Only 19 of the 151 studies reported on effectiveness of measures to reduce infection risk at individual level, of which 14 reported on face coverings. This suggests that there is an evidence gap for other measures within this category,such as hand and respiratory hygiene, ventilation and cleaning (studies that reported on packages of NPIs were excluded). Two-thirds of the evidence identified was based on modelling studies (100 out of 151 studies). There was a lack of experimental studies (2 out of 151 studies)Individual-level observational studies (22 out of 151 studies).On measures aimed to reduce infection risk at individual level The evidence available for this category is therefore likely to be weak, both in terms of study design and potential bias. Studies reporting on travel and border restrictionsa weak evidence base in terms of study design. Apart from test and release strategies for which 2 randomised controlled trials (RCTs) were identified, the body of evidence available on effectiveness of NPIs in the UK provides weak evidence in terms of study design, as it is mainly based on modelling studies, ecological studies, (relationship between outcome and exposure at a population level)mixed-methods studies and qualitative studies. For future pandemic preparednessA need to strengthen evaluation of interventions,and build this into the design and implementation of public health interventions,and government policies from the start of any future pandemic,or other public health emergency. The next steps are to critically appraise and synthesise the evidence identified on the effectiveness of individual NPIs,implemented in community settings to reduce the transmission of COVID-19 in the UK. There is also a need to review and assess the evidence on the economic impact of NPIs,as well as their wider impact, including on mental health and health inequalities.
