The delta variant is highly transmissible.
Compare that to the alpha variant, Around the world dominant strain for example
in the u.s.The largest survey of its kind tells us that having two doses of a
covid vaccine does give good protection researchers analyzed nearly three and a half million covid tests between December last year
and the first of august this month. Genetic material is made up of molecules
that can be represented as a series of letters.
Similar levels of virus in your nose
and throat as gets covered without having been vaccinated and that's completely
different from alpha was actually covered tended to have much less virus and
no symptoms and that does mean that there is the potential for people who get
covered after being vaccinated to still pass it on. The delta variant was
associated with an increased risk of covid19 hospitalization admission a hazard the ratio of 1.85. In the United States, viruses making up over 50% of all of our
new cases.
The covid-19 infections alpha two doses are still giving good protection against the infections with delta at Pfizer and AstraZeneca was there any data about any other vaccines in your survey we can take at a single dose of Moderna and actually a single dose of Moderna does very well. we can with two doses than being vaccinated at all very strong findings supporting vaccination really for everyone to think about with delta than alpha is the fact that does happen to get code after being vaccinated remember that's a much smaller chance. The delta variant it utilizes very specific types of proteins to enter into cells in the body.
It's important for people to understand
that there is that the potential risk of onward transmission it does und very
important because many decisions are being made about whether to allow
double jabbed people into venues onto airplanes on the base the thinking that
double jabbed unlikely to pass it on about transmission from people who've had
two vaccinations we weren't able to look at that directly it could be that you
have a high viral load for a less long period of time it could be that a virus is partly crippled by the immune system already about booster jabs for
those two already the goal of boosters is to really stop
hospitalizations and deaths and your second dose for AstraZeneca have
statistical certainty about Pfizer.
The average number of people that can
be infected by each person and so this is kind of just showing the spread or
transmissibility of the virus.
