Covid-19 vaccines have one goal: to fight and beat the disease and, thereby, put an end to the pandemic. But they go to war armed with a variety of weapons, approaches and genetic makeup. This nonuniformity, along with uneven degrees of success they offer, not to mention their cost that varies according to complexity of technology used to mass-produce them, add to the hesitation that has crept into the public mind. This explains why the government, in the exercise of its power and use of available resources, must exploit leadership and moral suasion to rally public support behind its multibillion-peso vaccination program.
