Calling it 'dangerous' trend, WHO cautions people against mixing and matching Covid vaccines

The WHO official argued that since there was little data available about the health impact, people should adopt cautious approach.

"It's a little bit of a dangerous trend here. We are in a data-free, evidence-free zone as far as mix and match," Soumya Swaminathan told an online briefing.

"It will be a chaotic situation in countries if citizens start deciding when and who will be taking a second, a third and a fourth dose."
