He said based on guidelines issued by the US Centers for Disease Control and Prevention (CDC) and the Food and Drug Administration (FDA), as well as medical research centres in other countries, these tests were not recommended.

“There are still no clinical guidelines for antibody tests that produce accurate results,” he told a press conference after visiting the Persada PLUS Integration Vaccination Centre (PPV) today.

A statement on the matter will be issued by the health ministry soon, Khairy said.

A study on the effects of taking the vaccine on the immune system was being conducted by the Institute for Medical Research (IMR) and the outcome of the study will be announced to the public, he added.

Meanwhile, on the surge in vaccination rate, with 98% of the adult population in the Klang Valley having received the first dose of the vaccine as of Aug 1, Khairy said the focus was now on states which showed an increasing trend in daily cases.

According to Bernama, the science, technology and innovation minister also said he would have an audience with the Sultan of Johor, Sultan Ibrahim Sultan Iskandar, tomorrow.

He would also brief the Johor government on plans to control the increase in cases in the state through various vaccination strategies.

On the daily vaccination rate, he said Malaysia now topped the list worldwide, but with the limited vaccine supply, it was difficult for the country to surpass the current rate of 400,000 to 500,000 doses a day.

“Not all of our vaccine supplies have arrived. The vaccines are delivered weekly. So, it’s very difficult to go beyond that,” he added.
