Two things going on here. One, Phizer was ordered to release a study that was as of February 28, 2021; nine months ago as of the publishing of this article.
Second, it appears as though the American Medical Association has also published a report about the harmful affects some have and are experiencing from the 'vaccine'. Bigger though is somebody posted a link to the article on Twitter and twitter gives you a warning (of course, right?) about proceeding to that link. You know, mis-information, damageing information, harmful to your computer, end of the world if you go there type warning. Ok, the last one I exagerated.
First below is the article about the Pfizer study with a link to it. Second is the link to the Twitter post mentioned. And last will be the actual Pfizer document.
