Interval between Pfizer-BioNTech doses can stretch to six weeks, says Khairy

PETALING JAYA: The interval between the first and second dose of the Pfizer-BioNTech Covid-19 vaccine can be stretched from three weeks to six weeks apart unless there is a variant of concern in the area, says Khairy Jamaluddin.

"Even though the strategy from three weeks to six weeks will allow us to administer the vaccine to more people, we also have to look at variants of concern which will impact the efficacy of the vaccine," the National Covid-19 Immunisation Programme coordinating minister said during a virtual press conference on Thursday (May 27).
