Chief scientist says organisation is awaiting data on studies combining vaccines but that health agencies can make decision to mix shots
The World Health Organization’s chief scientist has advised individuals against mixing and matching Covid-19 vaccines from different manufacturers, saying such decisions should be left to public health authorities.
“It’s a little bit of a dangerous trend here,” Soumya Swaminathan told an online briefing on Monday after a question about booster shots. “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.”
