Hello people!
I want to talk to you
about covid-19 vaccine
okay, the one developed by University of Oxford
together with AstraZeneca
() company, alright?
recently they publish
the... the results...
...for the... so the overall
eficacy of the vaccine
and... the number was 70%
Now, compared to the other two,
with numbers in the region of 90-95%
this would path ()?
however...
it turn out they
made a mistake
with about 3000 people volunteers
and... because they gave to
this people a lower dous...
() 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... you give
the full amount on the second
it looks like
the overall efficacy rises from 70 to 'round 90%
now taking into account
that this vaccine is cheaper
than the other two
between the region of 2-3 euros 'round and 20 or whatever
and... that it can be stored in fridgers...
...alright... at fridge temperature,
around 8 degrees positive,
(?) than minus 20 and minus 80
so, of course, all these two caracteristics...
...make this vaccines 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 make new trials now
but then, of course
some people are saying:
"ahh, if they are making new ones...
...is beacuse they didn't
do the right the first time...
...or someone"
so, it's tricky.
