ZURICH, Nov 23 — Swiss drugs regulator Swissmedic said today it approved the extension of a booster dose of Pfizer-BioNTech’s Covid-19 vaccine to everyone aged 16 years and over.

"This clears the way for wider use of the booster vaccination. High-risk individuals can still obtain a booster dose from age 12,” Swissmedic said in a statement. — Reuters
