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.
Defence Research and Development Organisation (DRDO) has developed an Ultra Violet (UV) disinfection tower for rapid and chemical-free disinfection of COVID-19 infection prone areas.
The equipment named UV Blaster is a UV-based area sanitizer designed and developed by Laser Science & Technology Centre (LASTEC).
The UV Blaster is useful for surfaces like electronic equipments, computers and other gadgets in laboratories and offices that are not suitable for disinfecting with chemical methods.
The product is also effective for areas with large flow of people such as airports, shopping malls, metros, hotels, factories, offices, etc.
The UV-based area sanitiser may be used by remote operation through laptop/mobile phone using WiFi link. This sanitiser switches off on accidental opening of room or human intervention. One more salient safety feature of the product is the key to arm operation.
