Oxford-AstraZeneca vaccine shows positive immune response in early study

A potential coronavirus vaccine developed by Oxford University with pharmaceutical giant AstraZeneca has produced a promising immune response in a large, early-stage human trial, according to newly released data published Monday in the medical journal The Lancet.

The researchers are calling their experimental vaccine ChAdOx1 nCoV-19 (AZD1222). It combines genetic material from the coronavirus with a modified adenovirus that is known to cause infections in chimpanzees. The phase one trial had more than 1,000 participants in people ages 18 to 55.

AstraZeneca’s shares were down 2.5% in midday trading.

The researchers said the vaccine produced antibodies and killer T-cells to combat the infection that lasted at least two months. Neutralizing antibodies, which scientists believe is important to gain protection against the virus, were detected in participants. The T-cell response did not increase with a second dose of the vaccine, they said, which is consistent with other vaccines of this kind.

“The immune system has two ways of finding and attacking pathogens — antibody and T cell responses,” Oxford professor Andrew Pollard said in a release. “This vaccine is intended to induce both, so it can attack the virus when it’s circulating in the body, as well as attacking infected cells. We hope this means the immune system will remember the virus, so that our vaccine will protect people for an extended period.”

The vaccine was found to be well-tolerated and there were no serious adverse events, according to the researchers. Fatigue and headache were the most commonly reported, they said. Other common side effects included pain at the injection site, muscle ache, chills and a fever.

Adrian Hill, director of Oxford’s Jenner Institute, told CNBC on Monday the strong immune response means the vaccine is more likely to provide protection against the virus, though nothing is guaranteed. He said scientists hope to begin human trials in the United States in a few weeks.

“We are using single-dose and two-dose of the vaccine,” he told “Worldwide Exchange.” “It looks like both give useful immune responses even though after two doses we see stronger immune responses.”

The potential vaccine is one of at least 100 being developed across the world for Covid-19, which has infected more than 14 million people worldwide and killed at least 606,206, according to data compiled by Johns Hopkins University. At least 23 of the vaccine candidates are already in human trials, according to the World Health Organization.

Last week, biotech firm Moderna released promising data on its vaccine trial, saying it generated a “robust” immune response. That trial included 45 healthy participants and was run by the National Institutes of Health.

Earlier this month, pharmaceutical giant Pfizer, alongside German drugmaker BioNTech, released positive results from its closely watched early-stage human trial. The company said its vaccine produced neutralizing antibodies in all participants who received two of the 10 or 30 microgram doses after 28 days, according to the preliminary data.

Just waiting eagerly to accept it.
They may give emergency authorization in October or November. Like giving it to health care workers and at risk people first. When it’s released publicly it won’t stop the spread in one week it will take time for enough people who got the vaccine to stop the spread.

WHO, vaccine developers and manufacturers should show some more responsibility. In this severe state of pandemic (where many kids lose their parents, parents lose their kids, etc) these medical bodies should fast track vaccine development and should not rely on conventional easy-going techniques. Mostly these manufacturers are much focused on the share market than the development.

Lack of coordination is clearly visible, only business and competition are going on.
The President of Brazil took covid 19, he was treated with (chloroquine / hydroxochloroquine) and within a week he was cured. They banned the use of this medicine in Brazil, claiming that it was dangerous for health, since this same medicine has been prescribed by doctors for years, for the treatment of malaria, lupuz and etc ... They prohibited the use of it, because this medicine is very cheap. They are trying to force the people to get the vaccine, and no one has yet been cured by the vaccine. The Brazilian president proved to everyone that using chloroquine cures covid 19, many people in Brazil have already been cured with this medication, including doctors.

May God protect us all!!! 🙏❤️

Billy White:
You don't say! An English medical journal -- which was recently discgraced when it was forced to retract an anti-HCQ study with obviously false data - is touting an English-made vaccine which requires not one but two undoubtedly expensive shots which generate antibodies... a week after we find out antibodies dissappear after 3 weeks... which the "journalist" seems unaware of... while they enthusiastically show the stock price? Seems legit!

Jim R

Let them do their work so that the vaccine isn't as dangerous as the virus itself. We should also be testing more with much faster turnaround times. Right now, COVID-19 is a raging wildfire - and virus can mutate as they spread. Have no idea what Trump and the GOP are thinking trying to CUT testing while at the same time pushing all schools to reopen. How on earth are we suppose to be safe with LESS TESTING?
