The Phase-2 clinical trial of the adenovirus vector vaccine or Ad5-nCoV was shown to induce an immune response and was safe, according to the information on the medical journal Lancet, last month. Conducted overseas, more participants will be included in the Phase-three trial of the CanSino vaccine. In order to launch Phase-3 clinical trials in those countries, the company said it is in talks with Russia, Brazil, and Chile.

The vaccine’s appropriate dosage to trigger a strong immune response, the longevity of the protection, and whether there are host-specific differences will be checked in the Phase-three trial.

There are various vaccines for COVID-19 in development around the world. The development of the world’s first vaccine against novel coronavirus was announced by Russian President Vladimir Putin last week. With 38 volunteers, the vaccine Sputnik-V’s clinical trials showed that all of the participants developed immunity and it was started on June 18.
