OTTAWA -- Canadian officials and doctors are defending sanctioning the mixing and matching of COVID-19 vaccines, after the World Health Organization’s (WHO) chief scientist issued a new caution about citizens opting to receive vaccines from different manufacturers, saying that the data remains limited on the practice.
On Monday, WHO Dr. Soumya Swaminathan said that the global health agency has received “a lot of queries” about people who have received a first dose of a COVID-19 vaccine from one pharmaceutical company and were planning to take another shot from a different authorized drug maker.
She called it: “A little bit of a dangerous trend.”
