Sanofi, the French drug maker has dropped the development of its mRNA Covid-19 vaccine. The company now aims to use the same technology for the development of vaccines for other diseases including flu.
COVID-19 Vaccination in India: Issues and Challenges
India’s COVID-19 vaccination program has been launched. It currently uses the vaccines Covishield and Covaxin. There are some issues and challenges that need to be overcome in order to vaccinate all Indians.

‘The results of Phase-II trial, released in May this year showed 95 per cent to 100 per cent seroconversion following a second injection, while a single jab produced high neutralising antibody levels among people with prior SARS-CoV-2 infection, suggesting the vaccine's strong potential for development as a booster shot. Together with GSK, Sanofi had aimed to produce up to one billion doses in 2021.’
"Taking into account public health needs and given sufficient mRNA Covid-19 vaccines supply can be expected going forward, we have decided not to pursue the development of our Covid-19 mRNA candidate into a Phase 3 clinical study," the company said in a statement. "We will focus our mRNA resources in our newly created mRNA Center of Excellence to address future pandemics and other infectious diseases and therapeutics where there is a strong unmet need," it added.
For the new study, Sanofi on September 14 acquired Translate Bio -- a clinical-stage biotechnology company that specialises in mRNA therapies. The two teams had worked closely together since 2018 to design and develop a messenger RNA (mRNA) technology platform for vaccines.
Test your Knowledge on Coronavirus (COVID-19)
Coronavirus is a large positive-strand RNA virus that is surrounded by a protein envelope. The virus obtains its name from the S protein spikes on its surface, which resemble a crown. The overall pattern of increasing coronavirus cases is shown to spike up with the “second wave” of COVID-19.
With spiking effects of the second wave of coronavirus, the best way to keep it at bay is to follow COVID-appropriate safety practices like wearing a mask, regularly cleaning your hands, and coughing into a bent elbow or tissue along with physical distancing (6 feet about 2 arm's length), that may help evade the severity of COVID-19 infection.

Human Trials of mRNA-based Flu Shot Begin
Moderna, the US-based biotechnology company has started human trials of an mRNA-based flu shot. The WHO estimates approximately 3-5 million severe cases of flu each year globally
