The third leg of the stool that has rights to this particular COVID vaccine. Pfizer, BioNTech and Fosun International in China. They bought an equity share of BioNTech earlier this year and have rights to this mRNA vaccine in China. I am not saying there is anything wrong with this but there will be a demand for manufactured doses split amongst these partners for sure. https://asia.nikkei.com/Spotlight/Coronavirus/Investors-applaud-Fosun-role-in-promising-Pfizer-COVID-vaccine Link to comment Share on other sites More sharing options...

The T response suggesting lasting effectiveness also super. The reality is FDA approval in second half of December. Very limited vaccine for those most at risk possible this year. 2 doses. Gottlieb suggested mid 2021 for the majority to be able to be vaccinated with 2 doses. I'll take it -Joel 1 Link to comment Share on other sites More sharing options...

odysee Posted November 14, 2020 #59 Share Posted November 14, 2020 Not looking for argumentations here, just trying to understand. I read a while ago that due to ethical reasons they could not test the vaccines being developed with the “live virus””, ie they could not willingly expose or infect trial persons with Virus, but would have to wait for accidental or coincidal exposures. So this would mean test result are pure chance as nobody can guarantee that both groups (the ones with real vaccine and the placebo group) would be accidentally exposed to same number and same load of infected persons ? Do I see this wrong ? Link to comment Share on other sites More sharing options...

Do I see this wrong ? No that is basically correct. So the rule of chance is minimized in these cases by doing very large and diverse trials and multiple demographics. That is why you cannot really say anything about efficacy and longer term safety issues in the initial (smaller) Phase 1 and Phase 2 trials. They would not stand up statistically speaking. The Phase 3 trials in this case have 10's of thousands of subjects and are "powered" (designed mathematically) to be statistically significant. It is somewhat more complicated but trying to give a straight forward answer. Does that help? 1 Link to comment Share on other sites More sharing options...
odysee Posted November 14, 2020 #61 Share Posted November 14, 2020 Yes it confirms that I have not misunderstood. Unfortunately it also confirms my reservations about the vaccine’s possible effectiveness. But I will remain hopeful that this or next vaccines can get us out of this miserable situation and back to life as it was before. Link to comment Share on other sites More sharing options...

So this would mean test result are pure chance as nobody can guarantee that both groups (the ones with real vaccine and the placebo group) would be accidentally exposed to same number and same load of infected persons ? Do I see this wrong ? Some numbers always helps me. Think of a group of 40 people. Half vaccinated. The odds today suggest that 1 at most would be exposed and infected with Covid through their regular daily activities. Thus no logical meaning. As Rick said change to a group of say 40000 with an infection rate of 1/2% - remember in a study each patient is repeatedly tested and almost 100% of cases, asymptomatic included, will be detected. Thus around 200 should be ultimately infected of the people in the study - 100 with placebo and 100 with vaccine. If after 2 months the number infected is 10X with placebo (say 50 and 5) then you can infer the vaccine prevented 45 cases or 90%. Link to comment Share on other sites More sharing options...

Reviewed by the dmsb, the company and the regulatory authorities. Link to comment Share on other sites More sharing options...

But it should actually make you much more comfortable really to get a vaccine that is effective in a 40,000 person trial. That comes directly from the field of mathematics called Probability and Statistics. I hope you can access a safe and effective vaccine soon wherever you live. we are all hoping for that! Be safe.

emmas gran Posted November 15, 2020 #65 Share Posted November 15, 2020 The guy from BioNtech was just on the BBC news and said it will be next Fall/Winter before the vaccine takes full effect.

TeeRick Posted November 18, 2020 Author #66 Share Posted November 18, 2020 Another look at the data for this vaccine pushed the efficacy to 95% with no safety issues of concern.

Caymus88 Posted November 19, 2020 #70 Share Posted November 19, 2020 Just had a visit to my doctor. he said this vaccine is projected to be effective for 6 to eight months. SO does this mean a booster every 6 or 8 months? Link to comment Share on other sites More sharing options...

SO does this mean a booster every 6 or 8 months? To be honest, I don't know your doctor but I am guessing that he/she is just speculating. There is no data yet on the longevity of the immune responses from these vaccines. So it is wait and see. It is possible that future boosters might be required or even a slightly different version of the vaccine yearly (like flu vaccines). On the other hand maybe not- maybe just the initial two doses will be fine. Nobody knows yet. 1 1 Link to comment Share on other sites More sharing options...

It wouldn't surprise me if one or more of the vaccines performs differently in different age groups, and it wouldn't surprise me if they don't. But there could be a perception that a 90% effective vaccine, for example, is inferior to a 95% effective vaccine, and that could be meaningless in the real world, and might be judged noninferior by the different regulatory authorities around the world.
