- Leading health experts have raised alarming questions about what if the world never sees a Covid-19 vaccine, as in the case of HIV and even dengue where there is no vaccine even after years of research.
- Currently, a vaccine candidate for Covid-19 was identified by researchers from the Oxford Vaccine Group and Oxford's Jenner Institute. The potential upcoming vaccine, ChAdOx1nCoV-19, is based on an adenovirus vaccine vector and the SARS-CoV-2 spike protein.
- What probably separates ChAdOx1 - known as recombinant viral vector vaccine - from the rest is the time it has promised to take in order to deliver mass quantities.
