According to the MoH, all second dose reservations will be rescheduled as of Sunday April 11 and will resume at a later time. The ministry added that due to a global shortage in vaccine manufacturing and delivery, they’ve provided more room for first timers, especially those in high risk categories, to receive theirs.
