Covid-19 Cases + Vaccination Tracker

A Chinese study looking at mixing Covid-19 vaccines showed that receiving a booster shot of CanSino Biologics’ vaccine after one or two doses of Sinovac Biotech’s vaccine yielded a much stronger antibody response than using the Sinovac shot as a booster. Participants who received a booster dose three to six months after a second Sinovac shot showed a 78-fold jump on average in neutralising antibody levels two weeks later.

Vaccine developer Novavax Inc has initiated an early-stage study to test its combined flu and Covid-19 vaccine. The trial, to be conducted in Australia, will enrol 640 healthy adults between the ages of 50 and 70, who have either been previously infected by Covid-19 or given an authorised vaccine at least eight weeks prior to the study.

China’s Sinovac Biotech Ltd announced that its CoronaVac vaccine has received approval from the Public Health Institute of Chile for emergency use for children and adolescents aged between six and 17.

Japanese drugmaker Daiichi Sankyo Co said its home-grown Covid-19 vaccine, a cutting-edge mRNA shot that is on the cusp of final clinical trials, could be used mainly as a booster starting next year for people who have already been immunised, Bloomberg reported.

BioNTech is set to request approval for countries to use its Covid-19 vaccine in children as young as five years old over the next few weeks and preparations for a launch are on track, according to a news report in Germany.
