辉瑞总裁打了四针？ 辉瑞总裁今天发推说他自己阳了，他打了四针，现在在吃自家产的那个药物。 I would like to let you know that I have tested positive for #COVID19. I am thankful to have received four doses of the Pfizer-BioNTech vaccine, and I am feeling well while experiencing very mild symptoms. I am isolating and have started a course of Paxlovid.— Albert
