    Symptom change and waning protection

    COVID cases no longer climbing as feared, except Scotland https://covid.joinzoe.com/post/covid-cases-no-longer-climbing-as-feared https://covid.joinzoe.com/data#levels-over-time Data from 21st August to 4th September COVID cases no longer climbing as feared Current cases, + 51,876 (symptomatic) Based on PCR and LFT test data from up to five days ago, n = 31,075 Down 9.2% from 57,158 new daily cases last week In the fully vaccinated population Cases, + 17,674 (symptomatic) (Last week’s average, + 17,342) New cases are the highest among the 0-18 and 18–35 year-old On average 1 in 90 people in the UK currently have symptomatic COVID UK R value = 1.0 Wales, 1.1 Scotland, 1.1 Scotland and England Cases remain highest in 0-19 years old Longer covid 894 people a day will go on to experience symptoms for longer than 12 weeks Professor Tim Spector It’s great to see the return to schools and summer festivals haven’t yet resulted in a spike in cases as feared. Worse in Scotland, rates are still rising Scottish hospitals could soon be overwhelmed The Scottish situation makes it clear we can’t be complacent about COVID as winter approaches We are still producing far too many Long Covid cases and hospitalisations unnecessarily For 521 days, ZOE and King’s College London have demanded cold and flu-like symptoms be recognised as common COVID-19 symptoms UK rates the highest in Europe, if the government continues with no restrictions, surely we should at least help people to recognise the symptoms early and know when to stay at home https://www.youtube.com/watch?v=ERHPwt9ExL8&t=1097s Learn more about your ad choices.

    Who fact checks the fact checkers

    Now all of the facts were equal, but some facts were more equal than others. Institute for Scientific Freedom https://www.scientificfreedom.dk/strategy/?utm_source=substack&utm_medium=email 1 All science should strive to be free from financial conflicts of interest. 2 All science should be published as soon as possible and made freely accessible. 3 All scientific data, including study protocols, should be freely accessible, allowing others to do their own analyses. Open letter from BMJ to Facebook about inappropriate censoring of serious data integrity issues in Pfizer’s COVID-19 vaccine trial https://www.scientificfreedom.dk/2021/12/18/open-letter-from-bmj-to-facebook-about-inappropriate-censoring-of-serious-data-integrity-issues-in-pfizers-covid-19-vaccine-trial/ https://www.bmj.com/content/375/bmj.n2635/rr-80 Fiona Godlee, editor in chief Kamran Abbasi, incoming editor in chief The BMJ Competing interests: As current and incoming editors in chief, we are responsible for everything The BMJ contains. Dear Mark Zuckerberg, The BMJ, one of the world’s oldest and most influential general medical journals. https://www.bmj.com/about-bmj/history-of-the-bmj 3rd October 1840 Serious concerns about the “fact checking” being undertaken by third party providers on behalf of Facebook/Meta. In September, a former employee of Ventavia, a contract research company helping carry out the main Pfizer covid-19 vaccine trial, began providing The BMJ with dozens of internal company documents, photos, audio recordings, and emails. These materials revealed a host of poor clinical trial research practices occurring at Ventavia that could impact data integrity and patient safety. We also discovered that, despite receiving a direct complaint about these problems over a year ago, the FDA did not inspect Ventavia’s trial sites. The BMJ commissioned an investigative reporter to write up the story for our journal. The article was published on 2 November, (2021) following legal review, external peer review and subject to The BMJ’s usual high level editorial oversight and review. Covid-19: Researcher blows the whistle on data integrity issues in Pfizer’s vaccine trial https://www.bmj.com/content/375/bmj.n2635 But from November 10, readers began reporting a variety of problems when trying to share our article. Some reported being unable to share it. Many others reported having their posts flagged with a warning about “Missing context … Independent fact-checkers say this information could mislead people.” Those trying to post the article were informed by Facebook that people who repeatedly share “false information” might have their posts moved lower in Facebook’s News Feed. Group administrators where the article was shared received messages from Facebook informing them that such posts were “partly false.” Readers were directed to a “fact check” performed by a Facebook contractor named Lead Stories.

    Risks and benefits with Professor Fenton

    Relative risk versus absolute risk with Professor Norman Fenton, Mathematician, Professor of Risk Information Management Professor Fenton, YouTube channel http://youtube.com/@normanfenton81 And Sub stack https://wherearethenumbers.substack.com/ normanfenton.com Link to video on Norman's channel https://www.youtube.com/watch?v=Va9aE98cFCA Download the slides used in this video https://d7694293-ffb8-4ed0-a014-3581d49070e4.usrfiles.com/ugd/d76942_9aec73e0e123495dba17f070437aadc8.pdf Nor What is risk information management? Thinking about risk, what do we mean by absolute risk and relative risk Sounds a bit like the level of risk can be presented in a way that gives a particular impression of a greater or a lessor risk or benefit? Are there occasions when a vested interest might want to give an impression of an increased benefit, or reduced risk from an intervention? How could choosing RRR versus ARR influence the impression given for adverse reactions is medical journals? Conversely Are there occasions when a vested interest might want to give an impression of a decreased risk from an intervention? So will RRR always be higher than ARR? Why can the RRR vary between populations and vary over time? So using one of the two measures to estimate the risk/benefit ratio would lead to different conclusions? How could risk / benefit reporting be optimised in the medical literature? Do you think the editors of prestigious international journals are aware of the differences between RRR and ARR? In the case of this paper from the Journal of Expert Reviews of Vaccines Efficacy and effectiveness of covid-19 vaccine - absolute vs. relative risk reduction https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9115787/ The original phase three data gave an efficacy for Pfizer vaccine, at preventing infection with SARS-CoV-2 of 95%, but it turns out the ARR was 0.84% Why are these figures so different? So is it fair to say that the ‘real world translation’ of the ARR of the Pfizer vaccine over 5 to 6 months of use increased to 3.7%? What do we mean by number needed to treat?
