CanSino Biologics’ single-dose Covid-19 vaccine, given at a lower dosage than that for adults, is safe and triggers an immune response in children aged six-17, results from a small trial showed.
Researchers decided to lower the dosage after a few participants developed fever and headaches graded at level 2 severity – the second-lowest of four levels.
In children, the lower dose triggered higher antibody levels than the dosage approved for use in adults in China, according to the peer-reviewed finding.

The results also showed that children given one lower dose had a stronger antibody response than adults who were given a booster shot 56 days after the first dose.
But the antibody readings did not show to what extent the vaccine could offer protection against Covid-19, researchers from a Chinese disease control agency, CanSino and other Chinese institutes cautioned in a paper.
