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.
