If there are enough people that have been vaccinated, then even if someone is infected, the vast majority of the people that this infected person interacts with will already be vaccinated and not be infected. This is why mass vaccination with an effective and safe vaccine remains a very powerful public health measure to protect against an infectious disease.

The vaccine takes time to be effective. From the point of taking the first dose, three weeks later, you take a second dose, and then maybe one or two weeks later before it's fully effective. So from the time of receiving the vaccine, to the point that it truly protects you against an infection you're looking at a month, five weeks or more. That means that we cannot wait until the situation in Singapore is bad before we start to vaccinate people. A vaccine by nature is a preventive measure. It is meant to protect people during peacetime such that when you're in a wartime scenario, when you're exposed to people potentially carrying the virus, you are protected from it.

The risk of mutation for coronaviruses is far lower than viruses such as flu. Thus far, the new strains have not mutated to the extent that vaccines are not able to protect against them.
