Aller bon train: A French expression you may hear today

Translated literally aller bon train doesn’t make much sense in English; it means ‘to go good train’.

Professor Jean-Françios Delfraissy, president of France’s Covid advisory body le Conseil scientifique, told France 2 this morning (August 25) it was likely that a “large portion of fully vaccinated people” in France would ultimately become eligible for booster doses.

Currently, people considered especially vulnerable to the virus are set to become eligible in September.

Plans to expand the French campaign may be influenced by promising results in Israel where booster doses have been given to older people since the end of July.

Less than four weeks later, a third of people over 60 have been vaccinated and Israeli studies have found that booster doses have significantly reduced infection and serious illness among this age group.

Signs indicate the Israeli campaign will continue to aller bon train – to move quickly – as booster doses are now being made available to people over 30.

The expression aller bon train is a shortened way of saying aller par un bon train – to take a good train.

Similar to Israel’s vaccine campaign, it means to go fast, at a regular and rapid pace, like a train speeding down the railway tracks.
