I hear that the Pfizer vaccine comes in pack of 975 doses. You can't take it if you are on anti-coagilants or if you've had previously had an allergic reaction to a vaccine. Getting the vaccine requires an initial consultation with a doctor where the questions are asked. If you pass the questions then they defrost and make up a dose for you and then inject you. It takes approx 1 hr 45 minutes per person for the vaccination end to end. Once a batch is made up they have 6 hrs to use it in.
If you must post totally false information about the vaccine can you do it in the dedicated vaccine thread. Better still don't post about it at all if you don't know what you are talking about.
The ONLY risk from having the vaccine if taking anticoagulants is bleeding from the injection site and that risk is negligible. It's even safe to have it if, along with other heart medication, you are taking asprin and an antiplatelet medication such as Prasugrel, which are taken for 12 months following the insertion of stents to treat a heart block.
The issues of allergies are a different matter and have been discussed at length on the relevant thread.
