Jab switch a big decisionThe Public Health Ministry's announcement that it will shift its vaccination policy to give the AstraZeneca Covid-19 vaccine as a second dose to those who received a Sinovac jab for their first shot is a major decision that will require massive downstream adjustments. The implications of the policy shift are many and possibly massive. Such a major shift in vaccine policy should be made only when there is enough scientific evidence to support it. Since only about 12% of the population have received vaccines, the priority should also still be to give a first jab to as many people as quickly as possible. Now that the AstraZeneca vaccine will be used as the second dose, will the supplies be delivered on time?
