The research published in
The Lancet is the first to report on the immunogenicity and safety of a Covid-19 candidate vaccine in children as young as three years.
CoronaVac was on Saturday approved for use in South Africa - with conditions - by the South African Health Products Regulatory (Sahpra).
The regulator, however, only approved the vaccine for adults aged between 18 and 59. The authorisation was based on the safety, quality and efficacy data submitted by Curanto Pharma to Sahpra between 22 March and 22 June, according to a News24 report.
