Hong Kong Recommends Single Pfizer COVID-19 Shot for Teenagers

A panel of health experts on Thursday recommended to the Hong Kong government using one single Pfizer COVID-19 shot for teenagers aged 12-17 following reports of heart inflammation side effects.

Professor Lau Yu-Lung, chair of the health committee, said the side effect “was more prevalent than originally thought.”

“Experts decided it was better for teenagers to get only one dose to greatly reduce the chance of heart inflammation. Hong Kong’s low COVID-19 risk also means that one dose should offer sufficient protection,” Lau added.

Pfizer said it recognized reports of myocarditis, an inflammation of the heart muscle, after vaccinations, but such side effects were “extremely rare.” 

Hong Kong has administered 448,800 doses for the 12-17 age group, and around 65% have had at least one vaccine dose.

England and Norway would also begin vaccinating their 12-15 age group with Pfizer/BioNTech shot, but the decision on second doses would come later.
