[4] 米国 US: HHS and Pfizer reach agreement to increase patient access to Paxlovid

...
Key features of today's agreement are:
 - Protecting individuals in public programs, particularly Medicare. Individuals on Medicare, Medicaid, and those who are uninsured will continue to be able to access HHS-procured Paxlovid for free through the end of 2024 via a patient assistance program. From 2025-2028, Pfizer will continue to run a patient assistance program for individuals who are uninsured or underinsured with HHS-procured Paxlovid. In parallel, Pfizer will operate a copay assistance program for individuals with commercial insurance through 2028.
 - Ensuring no HHS-procured product is lost to expiry. Up-to-date product will be refreshed from Pfizer through 2028, ensuring that the HHS inventory of Paxlovid will not expire and will include all new formulations of Paxlovid authorized or approved for use in the U.S.
 - Creating a stockpile for future emergencies. In addition to ensuring that HHS maintains every course of Paxlovid that it has purchased, Pfizer will provide HHS with a stockpile of an additional one million treatment courses to ensure preparedness for future COVID-19 surges.
 - Providing a smooth transition to the commercial market. HHS will ensure a smooth and predictable transition to the commercial market over the next few months while prioritizing and reserving our HHS-procured treatment courses for people with Medicare and Medicaid, and for those who are uninsured. During this transition to commercial distribution, Paxlovid will remain available for ordering from HHS through 15 Dec 2023.

Conclusions
Our results highlight the benefit of a booster dose in reducing ED attendances and hospitalizations amongst older adults aged 60 years or more with no documented prior SARS-CoV-2 infection, during an omicron XBB wave; up to and beyond 360 days post-booster. A 2nd booster provided further reduction.

ジンバブエで原因不明の死亡となった6頭のアフリカゾウ African Savannah elephants の体内から、これまで野生のゾウで確認されたことがない種類の細菌が検出された。2020年にこれらのゾウが死亡した原因は、敗血症によると研究者らはみている。
the journal Nature Communications に掲載されたこの研究で、同年に隣国のボツワナで356頭のゾウが死亡した手がかりがつかめるかもしれない。保護活動からにより Botswana's Okavango Panhandle で死亡したゾウが発見され、国際的な注目を浴びた。一部は、歩行や走行中に突然死したと考えられている。主に2020年8月から9月の間に North-Western Zimbabwe で突然死した35頭の死亡したゾウについての調査でわかった。the Victoria Falls Wildlife Trust の獣医師は、発見にはヘリコプターが必要だったと説明している。酷暑の中で防護衣を着けた状態で、15頭のゾウの死後解剖が行われた。このうち13頭が敗血症で死亡したと結論づけた。6頭から、Bisgaard taxon 45 と呼ばれる細菌が発見され、死因であった可能性があると考えられた..."[This type of bacteria] wasn't completely mysterious; it was known to exist," explained Prof Steinbach. "But it had not been associated with septicaemia and never been found in the African elephants."
