Coronavirus vaccine to be tested in UK from Thursday, government announces

Human trials of a potential coronavirus vaccine developed at the University of Oxford are to begin on Thursday, health secretary Matt Hancock has announced.

And one member of the Oxford team said that if trials are successful, millions of doses of vaccine could be available for use by the autumn of this year, in a breakthrough which would potentially signal the start of the world’s slow emergence from an outbreak which has already claimed 175,000 lives and caused devastating economic damage.

Speaking at the daily Downing Street press conference, Mr Hancock said the government was “throwing everything” at the search for a vaccine and announced he was providing £20m to the Oxford team to help fund its clinical trials, with a further £22.5m going to researchers at Imperial College London.

Despite a normal development time of 18 months or more for a vaccine, the Oxford researchers led by Professor Sarah Gilbert believe large-scale production could be under way as early as September – about nine months after the novel virus was first spotted in the Chinese city of Wuhan.

  • As of April 22, Singapore reported an additional 1,016 new infections, bringing the total number of cases to 10,141. There have been at least 12 fatalities so far, according to data tabulated by its Ministry of Health.
  • More than 8,000 cases so far have been linked to migrant workers living in dormitories.
  • “It is a bit embarrassing; we’ve controlled the inbound (cases) from the overseas patients returning, within the local community, the numbers have controlled somewhat  — we’re talking about 40 cases a day,” said Dr. Leong Hoe Nam, infectious disease specialist from Mount Elizabeth Novena Hospital. “But for the foreign workers who work in a dormitory, we really have a big problem controlling them.”

What types of drugs might work?

There are three broad approaches being investigated:

  • Antiviral drugs that directly affect the coronavirus's ability to thrive inside the body
  • Drugs that can calm the immune system - patients become seriously ill when their immune system overreacts and starts causing collateral damage to the body
  • Antibodies, either from survivors' blood or made in a lab, that can attack the virus


What is the most promising coronavirus drug?

Dr Bruce Aylward, from the World Health Organization, said remdesivir was the only drug that showed any signs of effectiveness, after he visited China.

The antiviral drug was originally designed to treat Ebola, but other options proved more effective.

It has since been shown to be effective at treating other deadly coronaviruses (Middle East respiratory syndrome and severe acute respiratory syndrome) in animal studies, leading to hopes it will also be effective against the Covid-19 coronavirus.

It is one of the four drugs in the WHO Solidarity trial and its manufacturer, Gilead, is also organising trials.

Can HIV drugs treat coronavirus?

There has been much talk, but little evidence, that a pair of HIV drugs - lopinavir and ritonavir - would be effective at treating coronavirus.

There has been some evidence they can work in the laboratory, but studies in people have been disappointing.

The combination did not improve recovery, reduce deaths or lower levels of the virus in patients with serious Covid-19.

However, as the trial was conducted with extremely sick patients (nearly a quarter died) it may have been too late in the infection for the drugs to work.


Can malaria drugs stop coronavirus?

Malaria drugs are part of both the Solidarity and Recovery trials.

Chloroquine, and a related derivative, hydroxychloroquine, may have antiviral and immune-calming properties.

The drugs have been thrust into the spotlight as potential coronavirus therapies, largely due to claims made by President Trump, but there is still scant evidence on their effectiveness.

Hydroxychloroquine is also used as a treatment for rheumatoid arthritis, because it can help regulate the immune system.

Laboratory tests have shown it can inhibit the coronavirus, and there is some anecdotal evidence from doctors saying it appears to help patients.

However, the WHO says there is no definitive evidence of its effectiveness.


What about immune drugs?

If the immune system overreacts to the virus then it can cause inflammation throughout the body. This is helpful for rallying the immune system to fight the infection, but too much can cause collateral damage throughout body and can be fatal.

The Solidarity trial is investigating interferon beta, which is used to treat multiple sclerosis, and lowers inflammation. Interferons are a group of chemicals released by the body when under attack by a virus.

The UK's Recovery Trial is investigating dexamethasone - a type of steroid used to reduce inflammation.

Can survivors' blood treat coronavirus?

People who survive an infection should have antibodies in their blood that can attack the virus.

The idea is you take the blood plasma (the part which contains the antibodies) and give that to a sick patient as a therapy.

The US has already treated 500 patients with what's known as "convalescent plasma", and other countries are getting involved too.

How long until we have a cure?

It is too soon to know when we might have a drug that can treat the coronavirus.

However, we should start to get the results of trials in the next few months. This is much earlier than we will know if a vaccine (which protects against infection rather than treat it) is effective.

This is because doctors are testing drugs that have already been developed and are known to be safe enough to use, whereas vaccines researchers are starting from scratch.

Some completely new, experimental, coronavirus drugs are also being tested in the laboratory but are not yet ready for human tests .

Why do we need a treatment?

The most obvious reason for wanting a treatment is it will save lives, but it could also allow some lockdown measures to be lifted.

Having an effective treatment would, in essence, make coronavirus a milder disease.

If it stopped people who were admitted to hospital from needing ventilation, then there would be less risk of intensive care units being overwhelmed, so controls on people's lives may not need to be as strict.

So how are doctors treating patients now?

If you are infected by coronavirus, then for most people it would be mild and can be treated at home with bed-rest, paracetamol and plenty of fluids.

But some people need more intensive hospital treatment, which involves oxygen support such as ventilation.

Young and middle-aged people, barely sick with covid-19, are dying from strokes

Doctors sound alarm about patients in their 30s and 40s left debilitated or dead. Some didn’t even know they were infected.

Despite all his medical knowledge, 31-year-old medical student and Ph. D. candidate Sean Doyle couldn't know for certain all the risks of the injection he had just received in his right shoulder at Emory University Hospital. Yes, of course he was told of the potential side effects, such as soreness in his arm, a fever, malaise. But when you are among the first people in the world to receive a vaccine injection, the real answer about the risks is simply "we don't know."

In fact, it's those very questions that he is helping us answer.
Sean is helping all of us figure out if it is safe, by putting up his hand first and volunteering. With that injection, Sean had become a critical part of the fastest moving vaccine trials in the history of the world, a vaccine for Covid-19.

Gilead reports ‘positive data’ on remdesivir coronavirus drug trial

Gilead Sciences said Wednesday it is aware of “positive data” from one of its studies looking at antiviral drug remdesivir as a potential treatment for the coronavirus.

The company also released data from its clinical trial involving patients with severe cases of Covid-19. The severe study is “single-arm,” meaning it will not evaluate the drug against a control group of patients who didn’t receive the drug.


The study tracked two groups of patients who were hospitalized with Covid-19. One group received a 5-day treatment of remdesivir, while the other took the drug for 10 days. The researchers said more than half of the patients in both treatment groups were discharged from the hospital by 14 days.

“These data are encouraging as they indicate that patients who received a shorter, 5-day course of remdesivir experienced similar clinical improvement as patients who received a 10-day treatment course,” said Aruna Subramanian, on the lead investigators of the study.
