Bharat Biotech set to develop and test vaccine for COVID-19

Bharat Biotech is getting into development and testing of a vaccine against COVID-19 called CoroFlu as part of an international collaboration of virologists and vaccine makers.

Background

CoroFlu is a one drop COVID-19 nasal vaccine built on a flu vaccine “backbone” that has been shown to be safe and well-tolerated in humans, in Phase I and Phase II clinical trials.

Details

Ø The company said that the product is part of an international collaboration of virologists at the University of Wisconsin–Madison and vaccine companies FluGen along with Bharat Biotech.

Ø CoroFlu will build on the backbone of FluGen's flu vaccine candidate known as M2SR. M2SR is a self-limiting version of the influenza virus that induces an immune response against the flu.

Ø Researchers will insert gene sequences from SARS-CoV-2, the novel coronavirus that causes the disease COVID-19, into M2SR so that the new vaccine will also induce immunity against the coronavirus.

Ø Under the collaboration agreement, FluGen will transfer its existing manufacturing processes to Bharat Biotech to enable the company to scale up production and produce the vaccine for clinical trials.

Ø Four Phase I and Phase II clinical trials involving hundreds of subjects have shown the M2SR flu vaccine to be safe and well tolerated.

Ø This safety profile, M2SR’s ability to induce a strong immune response, and the ability of influenza viruses to carry sequences of other viruses make M2SR an attractive option for rapidly developing CoroFlu as a safe and effective SARS-CoV-2 vaccine.

Ø M2SR is a unique form of the flu virus. It lacks a gene called M2, which restricts the virus to undergoing only a single round of replication in cells.

Ø CoroFlu, like M2SR, will be delivered intranasally. This route of administration mimics the natural route of infection by coronavirus and influenza and activates several modes of the immune system.

Ø Intranasal delivery is more effective at inducing multiple types of immune responses than the intramuscular shots that deliver most flu vaccines.

India Unemployment Rate Increased After Lockdown

The Centre for Monitoring Indian Economy (CMIE) has said that the unemployment rate shot up in March. The employment rate in the economy fell to an all-time low of 38.2 percent in March 2020. Background With the coronavirus outbreak severely affecting every country, its impact on an already hobbling Indian economy is set to be devastating if the latest data on unemployment rate is taken as an indicator. Details Ø The Labour Participation Rate (LPR) in March 2019 was 42.7 percent. This is the first time the LPR has fallen below 42 percent. Ø The monthly figures from the CMIE that were released recently also show a curious inversion. In urban India, unemployment among the uneducated is at a higher level than those with a graduate degree (13%), for the first time since early-2016. Ø Most of the people are employed in service sector jobs in construction, repair, or unorganized transport, all of which have come to a standstill due to the current lockdown.

Antarctica experiences first known heat wave

Researchers from the Australian Antarctic Program revealed that they had recorded temperatures as high as 9.2 degrees Celsius at Casey station in the continent east earlier this year, indicating a heatwave event. Background Heat waves are classified as three consecutive days with both extreme maximum and minimum temperatures. Between January 23 and 26, the station recorded minimum temperatures above zero degrees Celsius and a maximum temperature of 9.2 degrees Celsius. Details ➤ Scientists are concerned about the effect that the heat wave could have on Antarctica’s ecology, both positive and negative. ➤ Most life exists in small ice-free oases in Antarctica, and largely depends on melting snow and ice for their water supply. ➤ Melted ice flooding can provide additional water to these desert ecosystems, leading to increased growth and reproduction of mosses, lichens, microbes and invertebrates. However excessive flooding can dislodge plants and alter the compos

Universe expansion may not be Uniform

Astronomers have assumed for decades that the Universe is expanding at the same rate in all directions. A new study based on data from ESA's XMM-Newton, NASA's Chandra and the German-led ROSAT X-ray observatories suggests this key premise of cosmology might be wrong. Background Researchers set out to verify a new method that would enable astronomers to test the so-called isotropy hypothesis. According to this assumption, the Universe has, despite some local differences, the same properties in each direction on the large scale. Details Ø Widely accepted as a consequence of well-established fundamental physics, the hypothesis has been supported by observations of the cosmic microwave background (CMB). Ø A direct remnant of the Big Bang, the CMB reflects the state of the Universe as it was in its infancy, at only 380 000 years of age. Ø The CMB's uniform distribution in the sky suggests that in those early days the Universe must have been expand
