As sample sizes of studies involving local populations matter a lot, the Pakistan government has decided to almost double the sample size of clinical trial of a COVID-19 vaccine.

The target of vaccinating 10,000 volunteers has been enhanced to 18,000. However, it has been decided that the trial would be completed in the current month so that the process of registration of the vaccine could be started.

As many as 3,499 coronavirus cases and 39 deaths were reported in the last 24 hours.
