It is too early to determine the effectiveness of COVID-19 vaccines acquired by several countries for their populations, Minister of Health Dato Seri Setia Dr Haji Mohd Isham bin Haji Jaafar said during a press conference at the Ministry of Health (MoH) yesterday.

The minister said to test a vaccine’s effectiveness in ending the pandemic, at least 70 per cent of the population first need to get vaccinated.

“So far, the vaccine that has been produced needs to be taken in two doses within a period of 14, 21 or 28 days. It is too early to determine its effectiveness,” he said.

Dato Seri Setia Dr Haji Mohd Isham shared some vaccines – like Pfizer – require certain logistics storage as it needs to be kept between -70 to -80 degrees Celsius.

Some countries which acquired this type of vaccine encountered problems as the cold chain could not be maintained, resulting in thousands of the doses being disposed.

As such, the minister said the government will ensure the logistic requirements for certain vaccines can be met before acquisition.
