Bismillah. I've taken the first dose of the Sinopharm vaccine. There are two types of vaccines available. Sinopharm is among the old school traditional vaccines. That's the one I took. Pfizer, Moderna etc have developed a new generation of vaccine, of which the long term effects are yet to be known. I would hold on on those until the study is completed. May Allah Almighty protect us ALL from this and all other viruses, sicknesses and diseases. Amin
