The Serum Institute of India will ship the Oxford University/AstraZeneca Covid-19 vaccine to Canada in less than one month, Serum's chief executive said on Monday.

CEO Adar Poonawalla said on Twitter, referring to a brand name for AstraZeneca's vaccine.

The novel coronavirus may survive for far lesser time on porous surfaces such as paper and clothes than on impermeable surfaces like glass and plastic, a study by researchers from the Indian Institute of Technology (IIT) Bombay suggests. COVID-19, caused by the SARS-CoV-2 virus, is transmitted through respiratory droplets. The virus-laden droplets also form fomite upon falling on a surface, which serves as a source for infection spread. In the study, published in the journal Physics of Fluids, the researchers analysed the drying of droplets on impermeable and porous surfaces.
