I do not understand what the 5 year plan is. Even less what the 50 year plan is.<p>On one hand:<p>We are blessed to have access to mass genetic vector vaccines. Genetic vector vaccines are amazing at shaving off the sharp edge of the pandemic. Even after effectiveness drops against infection, they are still amazing at preventing severe infections. &quot;VE for severe disease is *still high* after 6 months - 94% for ages 40-59, 86% for 60+.&quot;, <a href="https:&#x2F;&#x2F;twitter.com&#x2F;_lewisy&#x2F;status&#x2F;1430291421085552641" rel="nofollow">https:&#x2F;&#x2F;twitter.com&#x2F;_lewisy&#x2F;status&#x2F;1430291421085552641</a>.<p>On the other hand:<p>* There is no path to ZeroCovid due to high airborne infectiousness, leaky genetic vector vaccines, immense human global population and reported animal reservoirs.<p>* The genetic vector vaccine effectiveness appears to diminish after ~6 months, thus booster shots.<p>* Leaky genetic vector vaccines are bound to give raise to vaccine-resistant variants, just like incomplete antibiotic courses give raise to antibiotic-resistant bacteria.<p>* Every time a new genetic vector vaccine variant is developed, it takes a long time to pass the FDA tests and even then it carries a tiny, but not zero, risk of ADE. OK, we&#x27;ll roll the Russian Roulette once. But we can&#x27;t forever play Russian Roulette with a mutating virus.

Will journalist ever report confidence intervals? The report says:<p>&gt; Adjusted VE during this Delta predominant period was 66% (95% CI = 26%–84%) compared with 91% (95% CI = 81%–96%) during the months preceding Delta predominance<p>So it&#x27;s not much accurate the 66%, it could be anywhere between 26% to 84%.

In the FDA&#x27;s press release yesterday [1], they justified Pfizer approval by saying the vaccine had a 91% effectiveness. But everyone knows that number is no longer true - the data was from March, before Delta. If the FDA were acting responsibly and credibly, they would have used the latest data, but then approval doesn&#x27;t look so favorable.<p>It&#x27;s probably relevant that Pfizer spent over $200M lobbying politicians over the past 20 years, more than any other pharmaceutical [3]. And Biden&#x27;s administration clearly weren&#x27;t happy with the FDA - just last week they said they are looking for a new head for November [3]. Interesting how approval came the next week. How much money does Pfizer stand to gain, once mandates and boosters? $15&#x2F;shot?<p>[1] <a href="https:&#x2F;&#x2F;www.fda.gov&#x2F;news-events&#x2F;press-announcements&#x2F;fda-approves-first-covid-19-vaccine" rel="nofollow">https:&#x2F;&#x2F;www.fda.gov&#x2F;news-events&#x2F;press-announcements&#x2F;fda-appr...</a><p>[2] <a href="https:&#x2F;&#x2F;jamanetwork.com&#x2F;journals&#x2F;jamainternalmedicine&#x2F;fullarticle&#x2F;2762509#ioi200006t1" rel="nofollow">https:&#x2F;&#x2F;jamanetwork.com&#x2F;journals&#x2F;jamainternalmedicine&#x2F;fullar...</a><p>[3] <a href="https:&#x2F;&#x2F;www.bloomberg.com&#x2F;news&#x2F;articles&#x2F;2021-08-19&#x2F;janet-woodcock-ruled-out-for-permanent-fda-commissioner-post" rel="nofollow">https:&#x2F;&#x2F;www.bloomberg.com&#x2F;news&#x2F;articles&#x2F;2021-08-19&#x2F;janet-woo...</a>

Does anyone know how the 66% effectiveness of the vacine compares to people who were exposed to COVID but never got the vaccine?
