>>13473791Astrazeneca is the most dangerous one by far. You got it totally wrong.
In the first world they don't give it at all to young people because of the cases of clots, which may be as high as 1 out of 27000 people.
Many people that received astrazeneca for their first dose, were given another one for the second one.
It also uses untraditional vaccine technology, it uses a chimp adenovirus (that is why it's called chadox ch from chimp, ad from adenovirus) with the spike of covid.
Sinovacc is very safe but the first dose gives you almost no protection at all, you only get moderate protection 2 weeks after the second dose. This is a traditional vaccine, like the flu vaccine that is released every year.
If you are young and not fat/asthmatic or something like that, and if your parents are vaccinated, I would get Sinovac.
If you are very worried about accidentally transmiting covid to your parents, get Pfizer. It's the best vaccine, but the most experimental one. But it has been authorized for teenagers in the first world, it seems safe.
