SINGAPORE -- Singapore has signaled an intention to make three doses of COVID-19 vaccines the standard for "full inoculation," likely sometime next year.
The city-state is looking to raise the bar on its vaccination program as it braces for a potential wave of infections caused by the highly mutated omicron variant, health authorities said on Tuesday. Even before the new threat emerged, there were already signs that vaccine-induced immunity fades over time, prompting the global introduction of booster shots.
