(1) I had somehow missed this bombshell: China skipped the Phase 3 clinical trial for its vaccine altogether and is now vaccinating its entire “People’s Liberation Army”, reports the Daily Telegraph. Dr. Campbell comments in his daily update. Epoch Times commentator Joshua Philipp (at 4:00 into the video) notes that, in parallel, it will be tested on 9,000 volunteers in Brazil: if these trials are successful, the vaccine will be manufactured in Sao Paulo and distributed free of charge. Free? Timeo
DanaosSinos et dona ferentes. Keep watching for some insight on ChiCom influence operations in Brazil from, admittedly, a stridently anti-CCP commentator.
(2) While everybody was preoccupied with COVID19 and with the US riots, China’s sham parliament rubber-stamped the extension of China’s national security law to the Hong Kong Special Administrative Region, de facto (if not de jure) abrogating the “One Country, Two Systems” agreement. The UK is extending an offer of residence, with a path to citizenship, to the 3 million Hong Kongers with “British National Overseas” status.
(3) “Infect me”. The Times of Israel has an interview with Keren P., a US-born army veteran who just graduated as a mechanical engineer from the Technion. She is one of 61 Israelis who have volunteered to be “guinea pigs” in a vaccine challenge trial through the 1daysooner nonprofit. In a “challenge trial”, people are first vaccinated, then deliberately exposed to the pathogen under controlled circumstances.
(5) Can you recondition an N95 mask? An article in ACS Nano studies the question experimentally. https://pubs.acs.org/doi/10.1021/acsnano.0c03597
Quoting from the abstract:
We investigated multiple commonly used disinfection schemes on media with particle filtration efficiency of 95%. Heating was recently found to inactivate the virus in solution within 5 min at 70 °C and is among the most scalable, user-friendly methods for viral disinfection. We found that heat (≤85 °C) under various humidities (≤100% relative humidity, RH) was the most promising, nondestructive method for the preservation of filtration properties in meltblown fabrics as well as N95-grade respirators. At 85 °C, 30% RH, we were able to perform 50 cycles of heat treatment without significant changes in the filtration efficiency. At low humidity or dry conditions, temperatures up to 100 °C were not found to alter the filtration efficiency significantly within 20 cycles of treatment. Ultraviolet (UV) irradiation was a secondary choice, which was able to withstand 10 cycles of treatment and showed small degradation by 20 cycles. However, UV can potentially impact the material strength and subsequent sealing of respirators. Finally, treatments involving liquids and vapors require caution, as steam, alcohol, and household bleach all may lead to degradation of the filtration efficiency, leaving the user vulnerable to the viral aerosols.
