The World Health Organization’s chief scientist warned against mixing and combining COVID-19 vaccinations from different manufacturers on Monday, calling it a “dangerous trend” due to the lack of data on the health consequences.
“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,” in an online briefing, Soumya Swaminathan said.
“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.”
