Quality of protection takes priority, says Khairy

PETALING JAYA: The dosing interval between the first and second dose of the Pfizer-BioNTech Covid-19 vaccine can be stretched from three weeks to six weeks but this move will depend on the prevalence of variants of concern (VOC) found in a locality, says Khairy Jamaluddin.

The National Covid-19 Immunisation Programme coordinating minister said the strategy of stretching the vaccine dosage internal from three weeks to six weeks will allow them to administer the vaccine to more people.
