Coronavirus live news: Sri Lanka to impose nationwide lockdown; one in 80 people in England had Covid last week
An analysis of the third and final stage of the research programme, released on Friday, found that more than 85% of all the infections connected to the 49 days of various outdoor sport, music and entertainment events came from the eight Euros games involved, and mainly the semi-final and final.
Reuters reports that the vaccine, ZyCoV-D, uses a section of genetic material from the virus that gives instructions as either DNA or RNA to make the specific protein that the immune system recognises and responds to.
Unlike most Covid-19 vaccines, which need two doses or even a single dose, ZyCoV-D is administered in three doses. The firm had applied for the authorization of ZyCoV-D on July 1, based on an efficacy rate of 66.6% in a late-stage trial of over 28,000 volunteers nationwide – making it among the less effective approved vaccines.
The generic drugmaker, listed as Cadila Healthcare, aims to make 100m to 120m doses of ZyCoV-D annually and has already begun stockpiling the vaccine.
Zydus Cadila’s vaccine, developed in partnership with India’s department of biotechnology, is the second home-grown shot to get emergency authorisation in India after Bharat Biotech’s Covaxin.
The drugmaker said in July its Covid-19 vaccine was effective against the new coronavirus mutants, especially the Delta variant, and that the shot is administered using a needle-free applicator as opposed to traditional syringes, Reuters reports.
