which blood type is shouldn't take astrazeneca vaccine?

Blood type has nothing to do with taking any vaccine or not. I suggest you rely on established validated medical websites and organizations for your medical education. 

If you start listening to antivaxxers then good luck to you. The web is full of **** and if you want to believe in it then there is no hope out there. 

There are no contraindications for the COVID vaccines with regards to ABO type and Rh. None.

"Astrazeneca vaccine," does not reject any blood type. Regardless of the blood type it depends on the person's immune system and reaction to the vaccine.

Personally I don't think it is a blood type.

There are people who have thicker blood than others, they cite healing from a cut faster or taking thinners aside from what is recommended by a doctor. Platelettes donation, some have higher counts.  I am one of them.

Donating blood is difficult for people with thicker blood. Can't tolerate it. I am not sure how they would test blood clotting factor, but if they can test this in a petrie dish and ask people the right questions they may be able to identify persons with higher risk vs those with lower risk. By doing that they can control what type of vaccine is used, and offer a treatment option for lower risk people who may have a propensity to developing clots.

Doctors would jump at it if they had a ready way to test.

Eugenicists answering doctors inquiry, and no pharmaceuticals contacting doctors. 

I am not a doctor or medical professional, but I know when they run across this, they have interest in learning. It could save some people's lives. Blood thinners are not for everyone and long term use has its own risks.

Any blood type i think But ask your doctor

Ask your doctor and NOT strangers on the internet.
