Hello people, em, I want to talk to you about Covid-19 vaccine, okay, the one developed by University of Oxford together with AstraZeneca, which is a company, alright! Recently they publish the results, so the overall efficiency of the vaccine and the number was 70%. Now, compared to the other two, with numbers in the region of 90/95%, this looked bad. However, it turned out they made a mistake with about 3,000 people volunteers and because, they gave to these people a lower dose regime of the vaccine, so basically they gave the same amount of liquid but there was less amount of vaccine in the liquid, it was deluded. So, this was a mistake, but it turns out that when you do that in the first dose and then you give the full amount on the second, it looks like, the overall efficacy rises from 70% to around 90%. Now taking into account that this vaccine is cheaper than the other two, it is in the region of 2-3 euros rather than 20 or whatever. And that it can be stored in freezers, right, at freeze temperature around 8 degrees positive rather than -20 or -80. So of course, this method, that all these characteristics made 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 is really good. So, you looks like they are going to make new trials now. But then of course some people are saying “Ahh, if they are making new ones is because they didn’t do it alright the first time” so on. So, It’s tricky.
