Head of the Independent Covid-19 Vaccination Advisory Committee under the Science, Technology and Innovation Ministry, Prof Datuk Dr Awang Bulgiba Awang Mahmud, told theSun that being given a choice would appeal to many. “This is because there are differences between vaccines in terms of severe adverse reactions, effectiveness, the possibility of vector immunity and the fact that some of these vaccines employ technologies that some people may not be comfortable with.”
