Just had a jab yesterday in Taguig. Sinovac. So far no untoward reaction. As in nothing. Thank God my body received it well. I had watched a video saying type O blood is LESS likely to be infected because it has more protection. Maybe that is true. Majority of peolple are having type O blood. The world's pop is about 7.8 billion and the infected is about 200million only worldwide. It is maybe true then.
