The findings, led by the National Institutes of Health, have not been reviewed or published by colleagues, but Professor Robin Shattock, Professor of Infection and Mucosal Immunity, Imperial College London, called the initial results “encouraging”.
He added: “This is a promising start, but efficacy data will be key followed by the ability to scale in a way that provides global access if the vaccine is successful.”
The second phase of the trial with around 600 people will start soon, while the third involving thousands of people will begin in July. Although future trials are successful, the Moderna vaccine will not be available until between January and June 2021.
US President Donald Trump said The US will begin mass production of any vaccine developed before it is fully approved so that it can be quickly distributed after it is stamped.
In addition to developing vaccines, the doctors also existing drug trials for viruses such as Ebola, malaria and HIV. Initial results appear to be promising but, until a complete clinical trial has been completed, doctors cannot ensure that the drug is effective.
That Chloroquine hydroxy experiments led by Oxford University, initially a malaria drug, praised by Matt Hancock, Secretary of Health, in April as a “major milestone” in the battle against Covid-19.
However, the results of an international study by WHO, published last week, showed that it increased the likelihood of inpatient deaths by nine to 21 percent.
Organization postponing his trial on Monday, citing security issues. But late on Tuesday, the leaders of the Oxford-led Recovery experiment, which operates in NHS hospitals, said they would continue based on their data not to show an increased risk.
Also been reported GSK and Sanofi have worked together to develop coronavirus treatments, and plan to have a vaccine ready for testing by the end of 2020.
British vaccine task force
On April 17, the government launch task force designed to “develop a coronavirus vaccine” quickly, and increase production so that it can be quickly produced and shipped in bulk.
This is led by Sir Patrick Vallance and Professor Jonathan van Tam, deputy chief medical officer, and members will include AstraZeneca and the Wellcome Trust.
The government initially allocated £ 14 million to hijack 21 coronavirus research projects – such as the work of scientists at the University of Oxford and Imperial College London. On 21 April, a further announcement of £ 44.5 million for the Oxford and Imperial trials further increased this funding.
A few weeks later the Business Secretary, Alok Sharma announced a further £ 84 million in new funding “to help speed up their work”.
He said: “This new money will help mass production of the Oxford vaccine so that if the current trial is successful, we have a dose to start vaccinating the British population immediately.”
To help the UK mass-produce vaccines, Sharma has announced the first vaccine-making innovation center in the UK is expected to open in the summer of 2021, a year ahead of schedule.
He said: “To further support our domestic manufacturing capabilities last month, I announced that the Government would accelerate the construction of the first vaccine manufacturing innovation center in the UK, based at Harwell in Oxfordshire.
“And today I can announce that we will invest up to £ 93 million further in the center making sure it opens in the summer of 2021, 12 months ahead of schedule.” The Center, which is already under construction, will have the capacity to produce enough vaccine doses to service the entire British population in just six months. “
