Why Pfizer vaccines are for townspeople and AstraZeneca for rural folk

KUALA LUMPUR: The Covid-19 vaccine developed by Pfizer and BioNTech would most likely be for urban areas while that by AstraZeneca would be for rural areas, says Khairy Jamaluddin.

The Science, Technology and Innovation Minister said this is because the vaccine doses from Pfizer require extra-low temperatures while the ones by AstraZeneca do not.
