Former minister Rafidah Aziz said she is "alarmed" by Putrajaya's plan to set up more "mega" Covid-19 vaccination centres amid crowding issues.<br /><br />She said this goes against the goal of having the widest reach possible and ensuring crowd control is orderly and manageable.<br /><br />She said all vaccination centres should be right-sized in every district by utilising the public halls there, where the standard operating procedures can be better enforced.
