message: Include  Vernon claimed that face masks are ineffective: * source A) Studies on the effectiveness of face masks
So far, most studies found little to no evidence for the effectiveness of face masks in the general population, neither as personal protective equipment nor as a source control.
    1.    A May 2020 meta-study on pandemic influenza published by the US CDC found that face masks had no effect, neither as personal protective equipment nor as a source control. * Source https://wwwnc.cdc.gov/eid/article/26/5/19-0994_article
    2.    A WHO review of ten randomized controlled trials of face masks against influenza-like illness, published in September 2019, found no statistically significant benefit. * Source https://www.who.int/publications/i/item/non-pharmaceutical-public-health-measuresfor-mitigating-the-risk-and-impact-of-epidemic-and-pandemic-influenza
    3.    A Danish randomized controlled trial with 6000 participants, published in the Annals of Internal Medicine in November 2020, found no statistically significant effect of high-quality medical face masks against SARS-CoV-2 infection in a community setting. * Source https://www.acpjournals.org/doi/10.7326/M20-6817
    4.    A large randomized controlled trial with close to 8000 participants, published in October 2020 in PLOS One, found that face masks “did not seem to be effective against laboratory-confirmed viral respiratory infections nor against clinical respiratory infection.” * Source https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0240287
    5.    A February 2021 review by the European CDC found no high-quality evidence in favor of face masks and recommended their use only based on the ‘precautionary principle’. * Source https://www.ecdc.europa.eu/sites/default/files/documents/covid-19-face-masks-community-first-update.pdf
    6.    A July 2020 review by the Oxford Centre for Evidence-Based Medicine found that there is no evidence for the effectiveness of face masks against virus infection or transmission. * Source https://www.cebm.net/covid-19/masking-lack-of-evidence-with-politics/
    7.    A November 2020 Cochrane review found that face masks did not reduce influenza-like illness (ILI) cases, neither in the general population nor in health care workers. * Source https://www.cochrane.org/CD006207/ARI_do-physical-measures-such-hand-washing-or-wearing-masks-stop-or-slow-down-spread-respiratory-viruses

    9.    An experimental study using virus aerosols, published in May 2022 in the Journal of Infectious Diseases, found that only professionally fit-tested N95/FFP2 masks, but not surgical masks or non-fitted N95/FFP2 masks, reduced viral loads in nostrils. * Source https://academic.oup.com/jid/article/226/2/199/6582941
    10.    A large Spanish school study, published in March 2022, found that “mask mandates in schools were not associated with lower SARS-CoV-2 incidence or transmission.” * Source https://adc.bmj.com/content/early/2022/08/23/archdischild-2022-324172
    11.    A May 2020 article by researchers from Harvard Medical School, published in the New England Journal of Medicine, concluded that face masks offer “little, if any, protection”. * Source https://www.nejm.org/doi/full/10.1056/NEJMp2006372
    12.    A 2015 study in the British Medical Journal BMJ Open found that cloth masks were penetrated by 97% of particles and may increase infection risk by retaining moisture or repeated use. * Source https://bmjopen.bmj.com/content/5/4/e006577 Dorothea99 (talk) 23:20, 4 January 2023 (UTC)
replies: text: Reading through these sources makes it clear that the attached comments are clearly being taken out of context. A number of the studies find the obvious: nonpharmaceutical cloth (homemade) masks are not as effective as medical / (surgical) masks. They don't suggest that 'masks don't work'. Similarly, a number of the studies state that small sample groups resulted in inconclusive results due to missing data, variable adherence, patient-reported findings on home tests with little to no blinding, making the data unreliable, meaning a solid conclusion could not be drawn upon - counter to the comments made above. It's also hardly surprising that many studies suggested the general public struggled with mask fitting, giving millions couldn't even figure out how to wear them over their noses and instead used said masks as a chin warmer, and that repeated use of a single use item wasn't conducive to protection. The studies above make it clear - masks are like condoms - you shouldn't reuse them, and even if used properly there's still a chance of catching or producing something you weren't hoping for.
