The World Health Organization's advisory council suggested on Friday that children aged 5 to 11 years old be given a reduced dose of Pfizer's and German partner BioNTech's COVID-19 vaccine.

The proposal comes following a meeting on Wednesday of the Strategic Advisory Group of Experts (SAGE) on Immunization to review the firms' vaccine. It is presently advised that people aged 12 and up receive the vaccine.

The recommended dosage for children under the age of 12 is 10 micrograms, rather than the 30 micrograms suggested for people aged 12 and up.

"With the exception of children with co-morbidities, this age range (5-11) is in the lowest priority usage category for immunization," SAGE chairman Alejandro Cravioto stated.

In high-priority populations like older persons and health workers, the panel further advised that booster doses of the COVID-19 vaccine be given 4 to 6 months after the first series is completed.
