Covid-19: Is vaccine booster shot necessary?
With many delays in the vaccine supply and campaigns, several countries are looking out for vaccine booster shots. But, health experts say it is too early to say these booster shots will be required.
World Health Organisation’s chief scientist Soumya Swaminathan has said there is not enough information to either confirm or dismiss the requirement for a booster shot after vaccination against Covid-19.
“We do not have the information that’s necessary to make the recommendation on whether or not a booster will be needed,” Soumya Swaminathan told Bloomberg.
“The science is still evolving,” the WHO chief scientist was quoted as saying.
