Hello people, um I want to talk to you about Covid-19 vaccine Ok, the one developed by University of Oxford together with Astrazeneca Just a company, alright? Resently they published the results for the, so the overall efficacy of the vaccine Uh, the number was 70% Now compared to the other two With numbers in the region of 90-95% This look bad However It turn out they made a mistake With about three thousand people volunteers And, because they gave to this people a lower dose, the gene of the vaccine So basically, they gave the same amount of liquid But there was less amount of vaccine in the liquid It was diluted So This was a mistake But it turns out that when you... do that In the first dose, and then you... And then you give the full amount in the second It looks like The overall efficacy Rises from 70 to round 90 percent Now, taking into account That this vaccine is cheaper than the other two Within the region of 2-3 euros round... 20 or whatever And That it can be storaged in fridges Alright At fridge temperature Around eight degrees positive Rather minus twenty, minus eighty So of course this... That... All of this two characteristics Make this vaccine much better So, the only problem would be the lower efficacy But If it turns out that the overall efficacy is actually in the region of 90% Then that's really good So it looks like they are going to do new trials now But then of course Some people are saying "uhm" If they are making new ones, it's because they didn't do it alright the first time, and so on So it´s tricky
