That may seem deliberately and needlessly lavish. Yet even boosting vaccine funding tenfold to $100bn or more, in line with the most ambitious proposals, pales in comparison with the $7trn which governments across the world have spent or pledged since the pandemic began in order to preserve incomes and jobs. The real extravagance would be to wait until a successful vaccine candidate emerges before rushing to boost production. In terms of the economic output that is saved, to say nothing of lives, it would make sense for the world to spend as much as $200bn on bringing forward an effective covid-19 vaccine by just one week.
What's the subject of this sentence? Does it miss a "it" before pales?
