Washington, Jul 1: The United States has approved four coronavirus vaccine candidates for clinical trials, Food and Drug Administration (FDA) head Stephen Hahn told reporters.

"Four vaccines have been approved for moving into clinical trials... and another six are in the pipeline for us to review," Hahn said during a press briefing on Tuesday.

The US Administration launched in May Operation Warp Speed, a joint project of Health and Defense Departments, which aims to deliver 300 million doses of a vaccine for COVID-19 by January 2021.

The country's top pandemics expert Anthony Fauci warned on Tuesday, however, that there is no certainty the United States will be able to develop a vaccine against COVID-19 that works and will be safe.

Data on vaccine effectiveness, he added, may be available in the winter or early next year.

A shrimp seller at the wet market in the Chinese city of Wuhan believed to be the centre of the coronavirus pandemic, may be the first person to have tested positive for the disease, a media report said on Saturday.

The report by the London-based Metro newspaper said that 57-year-old woman, named by the Wall Street Journal as Wei Guixian, was selling shrimp at the Huanan Seafood Market when she developed what she thought was a cold last December.

Chinese digital news outlet, The Paper has said that she may be epatient zero'.

Wei was told by doctors her illness was "ruthless" and other workers at the market had come to the Wuhan Union Hospital with the same symptoms, the Metro newspaper report quoted the outlet as saying.

"Every winter, I suffer from the flu, so I thought it was the flu," the woman was quoted as saying by The Paper news outlet.

The shrimp seller added that she believed she contracted the coronavirus from the shared toilet in the market.

She said the fatal disease would have killed fewer people if the government had acted sooner.

Wuhan Municipal Health Commission has confirmed that Wei was among the first 27 people to test positive for the coronavirus.

It said she was one of 24 cases with direct links to the market, the Metro newspaper reported.

Though Wei may be "patient zero", it does not mean she is the first person to have contracted the virus, added the Metro report.

Chinese researchers have claimed that the first person diagnosed with the airborne virus had no contact with the seafood market and was identified on December 1, 2019.

Wei was later quarantined when a connection was made between the bug and the market before recovering in January.

As of Saturday, the global number of coronavirus cases stood at 104,837 with 27,862 deaths, according to the latest update by the Washington-based Johns Hopkins University.

The US has the highest number of cases at 104,837, followed by Italy 86,498 and China 81,948.

Italy has recorded the highest number of fatalities with 9,134 deaths, followed by Spain and China, at 5,138 and 3,299, respectively.

Washington, May 19: As the scientists across the world are struggling to develop a vaccine for combating coronavirus, US drugmaker Moderna announced on Monday (local time) that the phase I trial of its Covid-19 vaccine has shown positive early results.

The company is hopeful that it's vaccine could be available to the public as early as January next year. Several firms across the world are in the race to develop a vaccine for the deadly virus which has claimed over 3 lakh lives worldwide.

CNN citing Dr. Tal Zaks, Moderna's chief medical officer reported that "if future studies go well, the company's vaccine could be available to the public as early as January".

"This is absolutely good news and news that we think many have been waiting for for quite some time," Zaks was quoted as saying.

Moderna, based in Cambridge, Massachusetts announced that the vaccine developed neutralising antibodies to the virus at levels reaching or exceeding the levels seen in people who have naturally recovered from Covid-19, reported CNN.

These will be followed by phase 2 trials and phase 3 trials, which Moderna plans to start in July.

President Donald Trump had on Friday said that that the United States will be able to deliver a few hundred million doses of COVID-19 vaccine, under 'Operation Warp Speed', by the end of this year.

"I have very recently seen early data from a clinical trial with a coronavirus vaccine and this data made me feel even more confident that we'll be able to deliver a few hundred million doses of vaccine by the end of 2020 and we will do the best we can," Trump had said at a press conference at the White House on Friday.
