疫苗在Duke大学的实地测试中，看来是毫无防感染作用了。

王明鉅：抗寄生虫药加微封城 印度北方邦抗疫成就惊人

抗寄生虫老药「伊维菌素（Ivermectin）」是否能够有效对抗新冠疫情？这个话题从今年6月以来在全球各地就不断受到讨论。台大癌医副院长王明鉅近日则在脸书表示，他亲自写信给成功控制疫情的印度北方邦一位Surya Kant医师，了解到他们利用伊维菌素与微封城这两大利器对抗疫情，让人口数高达2.4亿人的北方邦近日单日死亡数仅1人。
不过今年6月时指挥中心曾经公开表示不建议使用伊维菌素，美国疾病管制暨预防中心（CDC）和FDA也明确表示，没有可靠的科学证据支持伊维菌素可以治疗或预防新冠病毒。但近日美国的伊维菌素需求仍大增24倍。
王明鉅说，他是7月底在《纽约时报》看到一则报导〈More covid mystery〉，才开始研究疫情曾经非常猛烈的印度，过去2个月何以大幅平息？其中印度北方邦的变化最惊人，今年4月24日新增病例3万7944人，1个月后减为3894人，2个月后再骤降为224人。最新的数据是9月10日新增确诊9人，且最新1周的单日平均死亡数是1人，疫情控制成果「非比寻常的惊人」。
印度没有莫德纳或BNT疫苗，只有英国的AZ、俄罗斯的Spuntik V及印度自己研发生产的Covaxin等3种疫苗，北方邦疫苗打得也不是非常多，完整打完2剂的只有16％，为何疫情控制得比美国、英国、德国、以色列还成功？
为了厘清疑问，王明鉅直接写信给北方邦King George Medical University的Surya Kant医师。Surya Kant医师去年4月被政府委托到印度最早爆发疫情的Agra地区，了解当地疫情传播的状况，并接受当地一位医师的建议，使用伊维菌素治疗新冠。虽然当时缺乏大规模临床研究，但是伊维菌素安全、便宜、容易取得，小组成员医师使用的经验都非常正面，因此北方邦政府批准用于治疗早期的确诊病患，以及密切接触者的预防。
王明鉅说，伊维菌素对人类健康的贡献巨大，发明它的2位日本与美国的学者与发明青蒿素治疗疟疾的中国大陆学者屠呦呦，在2015年同时荣获诺贝尔生理及医学奖。
王明鉅说，Surya Kant的信里面提到，他们利用Ivermectin与Doxycycline加上锌与维生素C与维生素D等辅助成分的组合，很成功地击退了印度的第一波疫情，也在今年4月到6月再度击退了侵犯北方邦的第2波Delta变种病毒疫情。
此外，北方邦政府还配合大规模的宵禁措施及较小规模的微封城，确诊者与接触者立即全部投药治疗，让北方邦的每天新确诊人数减少了99.5％，且维持到9月。
王明鉅说，看过Surya Kant教授的访谈，再查阅过他提到的许多文献，并了解印度北方邦所採行的各种措施，就会知道北方邦的防疫成果不再神秘。
北方邦政府还配合大规模的宵禁措施及较小规模的微封城，确诊者与接触者立即全部投药治疗，让北方邦的每天新确诊人数减少了99.5％，且维持到9月。
在印度，宵禁封城都意义不大。密度太大，管理太难。没有疫苗，只有老药。结果就这样了。
其实短时间压制疫情，不难。
最难的是，维持到9月。这五个字。世界上没几个大国做到的。

Duke现在第六周，阳性已经从第一周的370，降到一周37。
可能开学时party太多，近距离接触太多。
现在开始上课考试了，传染几率降低……
疫苗不是盖的，只要不是太多party，管用……

DUKE 在8月30日，被迫实行新的covid限制措施。执行成本昂贵措施。这才把疫情压下来。所以，基本上他们近期的数字，已经与疫苗关系不大了。实际上可能是严格的物理隔断，和大规模的免费PCR的成果。可惜。疫苗按照原本的效益走，DUKE就不会在八月底，宣布极其严格的限制和测试措施。可惜。在防感染前线，疫苗没用（没有实际上断掉病毒的传染途径）。
As a result, the following new guidelines will be in effect starting Monday, August 30:
We want to be clear: the problem is not our people, the problem is COVID-19. Our Duke community has been extraordinarily united and resilient in fighting, and adapting to, this pandemic over the last 19 months. Your efforts have made it possible to fulfill our educational commitment to our students, to advance knowledge and discovery through our research, and to serve our region and society.
And yet, we must continue to do more. This is a time to be prudent, to take care of ourselves and each other so we can continue our important mission, which is now more important than ever.
As a result, the following new guidelines will be in effect starting Monday, August 30:
- Masks will now be required on the Duke campus in all indoor and outdoor locations, unless you are exercising [outdoors] alone, eating or drinking, or otherwise not around others. After vaccinations, masks are the best way to prevent the spread of COVID. We have seen this on campus and in our health system.
- Indoor group seating at Duke Dining facilities will be temporarily suspended. All Duke Dining facilities will transition to grab and go, and more than 25 tents have been erected across the campus to provide outdoor seating for meals and other gatherings.
- Given the absences in some undergraduate classes due to increased number of students in isolation, faculty teaching undergraduate courses have the option to teach remotely for the next two weeks if they would prefer. This is not a requirement but an accommodation to allow for increased flexibility as needed; those who are able to continue teaching in person should certainly do so.
- New limitations will be placed on student activities to reduce the possibility of COVID transmissions. Individuals and groups that violate these limitations will face disciplinary consequences. Further information will be provided directly to students.
- The COVID-19 vaccination will now be required for ALL Duke faculty and staff as a condition of employment. Details will be provided directly to those employees who have not yet submitted proof of vaccination or an approved medical or religious exemption, as well as their deans or vice presidents. As of today, 92% of our 22,136 faculty and staff are fully vaccinated.
We want to be clear: the problem is not our people, the problem is COVID-19. Our Duke community has been extraordinarily united and resilient in fighting, and adapting to, this pandemic over the last 19 months. Your efforts have made it possible to fulfill our educational commitment to our students, to advance knowledge and discovery through our research, and to serve our region and society.
And yet, we must continue to do more. This is a time to be prudent, to take care of ourselves and each other so we can continue our important mission, which is now more important than ever.
