"This study provided in vivo evidence that inadvertent intravenous injection of COVID-19 mRNA vaccines may induce myopericarditis. Brief withdrawal of syringe plunger to exclude blood aspiration may be one possible way to reduce such risk."
Is this really a problem? To extract blood the nurse must aim for a vein, and it's a long process with many steps, and sometimes they must retry a few times before success.
And I think for the vaccine they use a part of the arm without major veins, to avoid complications, bleeding and bruises.
