Effectiveness doesn’t really mean much between these vaccines. Please watch this video: https://youtu.be/K3odScka55A https://youtu.be/K3odScka55A From what we know so far, any of the approved vaccines are excellent and no one knows for sure if one is better than the other. The only logical thing to do is get what is offered to you as soon as possible.

That video is bullshit (and Vox is a publication that in Feb 2020 was pushing the "just a flu" narrative). The effectiveness is measured as 1-(Nnotinfected / (Ninfected + Nnotinfected)). The video claims that when the study was done during the surge or in "other countries", the effectiveness might be different because Ninfected is higher, which makes no sense at all, since the probability of the vaccine protecting you shouldn't change based on how the virus is spreading in the general population. For a set of 100 placebo and 100 vaccinated, even if all 100 are infected, the vaccinated segment should be as protected as possible. 95% efficacy means only 5 in the vaccinated are infected. 66% efficacy means 50 in the vaccinated are infected.

  That's not what they are claiming. They are claiming that the chance that a vaccinated person will get the disease is higher if that person is subject to more exposure events. What they say about trials during surges then follows from that. For the part about other countries, what they are saying is that there were more infectious strains circulating in those countries during the trial, so you can't compare to trials done before those strains were circulating.

    bro, you are missing out the news and the point of this whole post, pfizer is 90% effective against all current strans overral, even the nasty ones Unless you are claiming that right now there are less strains around, compared to october-novemeber (when the J&J data was compiled) This news just solidifies the argument that the mRna vaccines are much better. Suggesting otherwise is just either ignorance, or willful lie (let other take it, so i have more for me)
