Synopsis: Every first and third Wednesday of the month, The Straits Times helps you make sense of health matters that affect you.

A Covid-19 infection confers natural immunity but the question is how long will it last. Israel has given some people a fourth dose, which is the second booster shot.

In Singapore, Health Minister Ong Ye Kung had said that the question of whether further booster shots are necessary is still a matter of debate among scientists studying the coronavirus, and that there are no active plans to administer a second booster. But will we eventually need one?

In our previous episode, Prof Teo Yik Ying, the dean of the NUS Saw Swee Hock School of Public Health, said Covid would inevitably catch up with all of us at some time. In this mini episode, ST senior health correspondent Joyce Teo asks him about the probability of us needing a second booster dose.
