Pfizer has officially submitted a demand to the US government to approve the use of its COVID vaccine for children aged five to 11.
In its official application, the company said its research shows no adverse side effects for the age group. Bur, it recommends smaller dose.
Pfizer said its research showed that young children should get a third of the vaccine dose.
After two doses, five to 11-year-olds developed virus-fighting antibody levels just as strong as teens and young adults get from regular-strength shots, the company said.
Pfizer further studied the lower dose in 2,268 volunteers aged five to 11, and has said there were no serious side effects.
However, the study is not large enough to detect any extremely rare side effects, such as the heart inflammation that has sometimes occurred after the second dose of the regular-strength vaccine, mostly in young men.
New Zealand has earlier reported its first death linked to the Pfizer Covid-19 vaccine.
The health ministry declared that a woman suffered a rare heart muscle inflammation side effect after receiving her first batch.
