The phase-I human clinical trial of India's first indigenously-developed Covid-19 vaccine candidate, Covaxin, has shown "encouraging" results, according to the principal investigator of the vaccine trial team.
"First part of phase-1 of vaccine trial (Covaxin) has been completed. 50 people across India were administered the vaccine and the results were encouraging. Six people were administered vaccine on Saturday under the second part of phase-1," Dr Savita Verma, principal investigator of the vaccine trial team, told news agency ANI.

Telangana based Bharat Biotech's Covaxin, along with ZyCoV-D, are the only two vaccine candidates to have got a nod from the Drugs Controller General of India (DCGI) to conduct human trials. They have been developed by Hyderabad-based Bharat Biotech in collaboration with Indian Council of Medical Research and the National Institute of Virology.
On July 17, Haryana Health Minister Anil Vij had announced that the human trial of Covaxin began at Rohtak's Post-Graduate Institute of Medical Sciences.

Later, the phase-I trial began at the AIIMS on July 24, with the first dose of the injection given to a man, who is in his 30s. Over 3,500 volunteers have already registered themselves for the trial at AIIMS, of whom the screening of at least 22 people is underway, informed AIIMS professor Dr Sanjay Rai.
AIIMS-Delhi is among the 12 sites selected by the Indian Council for Medical Research (ICMR) for conducting phase I and II randomised, double-blind, placebo-controlled clinical trials of Covaxin. The phase-I human trials have so far begun in AIIMS Patna and few other sites too.

In phase I, the vaccine would be tested on healthy 375 volunteers with no co-morbid conditions aged between 18-55 years and a maximum of 100 of them would be from AIIMS. The second phase would include around 750 volunteers from all 12 sites together and about 750 people between the age group 12-65 years will be selected.
"In the first phase, we see the safety of the vaccine which is of primary importance and the dose range is also calculated," AIIMS Director and leading pulmonologist, Randeep Guleria had said.

Entire earth vibrating less due to Covid-19 lockdowns: Study

LONDON, JULY 24 : In a study conducted in 117 countries, researchers have found that the world is experiencing the most dramatic reduction in the seismic noise (the hum of vibrations in the planet's crust) in recorded history due to global Covid-19 lockdowns.
Measured by instruments called seismometers, seismic noise is caused by vibrations within the Earth, which travel like waves and the waves can be triggered by earthquakes, volcanoes, and bombs - but also by daily human activity like travel and industry.

This quiet period, likely caused by the total global effect of social distancing measures, closure of services and industry, and drops in tourism and travel, the study published in the journal Science, reported.
The new research, led by the Royal Observatory of Belgium and five other institutions around the world including Imperial College London (ICL), showed that the dampening of 'seismic noise' caused by humans was more pronounced in more densely populated areas.
"Our study uniquely highlights just how much human activities impact the solid Earth, and could let us see more clearly than ever what differentiates human and natural noise," said study co-author Stephen Hicks from ICL in the UK.
For the findings, the research team looked at seismic data from a global network of 268 seismic stations in 117 countries and found significant noise reductions compared to before any lockdown at 185 of those stations.


Researchers tracked the 'wave' of quietening between March and May as worldwide lockdown measures took hold.
The largest drops in vibrations were seen in the most densely populated areas, like Singapore and New York City, but drops were also seen in remote areas like Germany's the Black Forest and Rundu in Namibia.
Citizen-owned seismometers, which tend to measure more localised noise, noted large drops around universities and schools around Cornwall, UK and Boston, US - a drop in noise 20 per cent larger than seen during school holidays.
The findings showed that countries like Barbados, where lockdown coincided with the tourist season, saw a 50 per cent decrease in noise.
"The changes have also given us the opportunity to listen in to the Earth's natural vibrations without the distortions of human input," the study authors wrote.
Earlier in April, a study published in the journal Nature, reported at least a 30 per cent reduction in that amount of ambient human noise since lockdown began in Belgium.

If you are active on social media, you must have come across a video of a girl dancing to welcome her sister, who defeated the novel coronavirus. The video of the girl dancing to the song Tai Tai Phish from the film Chillar Party has been going viral.
If you haven’t seen the clip yet, have a look:

The girl in the video is Saloni Satpute. With the energetic dance, she welcomed her sister, who defeated the novel coronavirus and returned home. Saloni is a resident of Pune and recently her entire family apart from her were tested coronavirus positive.
It all began when Saloni’s father was tested positive and was taken to a hospital. After that, four other members of her family were hospitalised and she was left alone at home. Her parents came back early, but it was her sister, who was discharged from the hospital last.
The video shows the 23-year-old girl welcoming her sister in the most joyous manner. The dance was also a message to Saloni’s neighbours, who cut ties with her, while she was alone at home and taking care of herself.
Twitter loved Saloni and everything about the video, from her energetic dance moves to the love that she showed for her sister.
