A coronavirus vaccine developed by the University of Oxford appears safe and triggers an immune response.
Trials involving 1,077 people showed the injection led to them making antibodies and T-cells that can fight coronavirus.
The findings are hugely promising, but it is still too soon to know if this is enough to offer protection and larger trials are under way.
The UK has already ordered 100 million doses of the vaccine.
The vaccine – called ChAdOx1 nCoV-19 – is being developed at unprecedented speed.
It is made from a genetically engineered virus that causes the common cold in chimpanzees.
It has been heavily modified, first so it cannot cause infections in people and also to make it “look” more like coronavirus.
Scientists did this by transferring the genetic instructions for the coronavirus’s “spike protein” – the crucial tool it uses to invade our cells – to the vaccine they were developing.
This means the vaccine resembles the coronavirus and the immune system can learn how to attack it.
Much of the focus on coronavirus so far has been about antibodies, but these are only one part of our immune defence.
Antibodies are small proteins made by the immune system that stick onto the surface of viruses.
Neutralising antibodies can disable the coronavirus.
T-cells, a type of white blood cell, help co-ordinate the immune system and are able to spot which of the body’s cells have been infected and destroy them.
Nearly all effective vaccines induce both an antibody and a T-cell response.
Levels of T-cells peaked 14 days after vaccination and antibody levels peaked after 28 days. The study has not run for long enough to understand how long they may last, the study in the Lancet showed.
Prof Andrew Pollard, from the Oxford research group told the BBC: “We’re really pleased with the results published today as we’re seeing both neutralising antibodies and T-cells.
“They’re extremely promising and we believe the type of response that may be associated with protection.
“But the key question everyone wants to know is does the vaccine work, does it offer protection… and we’re in a waiting game.”
The study showed 90% of people developed neutralising antibodies after one dose. Only ten people were given two doses and all of them produced neutralising antibodies.
“We don’t know the level needed for protection, but we can maximise responses with a second dose,” Prof Pollard told the BBC.
Yes, but there are side-effects.
There were no dangerous side-effects from taking the vaccine, however, 70% of people on the trial developed either fever or headache.
The researchers say this could be managed with paracetamol.

Justin Kodua Frimpong files nomination to seek re-election as NPP General Secretary

General Secretary of the New Patriotic Party (NPP), Justin Kodua Frimpong, has filed his nomination to contest the position of General Secretary again as the party begins its rebuilding efforts ahead of the 2028 general elections.
He was accompanied by party stalwarts and supporters who were in high spirits, expressing confidence that he is the right person to hold the position.
Speaking after filing his nomination, Mr Kodua Frimpong assured the rank and file of the party that he would not disappoint them.
“I can assure you that the faith the rank and file of the party have had in me, I will never disappoint them,” he said.
He also pledged to run a clean campaign devoid of personal attacks.
“I can assure you that our internal campaign will be devoid of personal attacks,” he told his fellow contestants and the rank and file of the party as he seeks to retain his position.
His tenure has seen the party through the 2024 general elections, where the NPP lost power to the National Democratic Congress (NDC) after eight years in government.
The party is currently in a rebuilding phase, with internal elections scheduled to elect new national executives to lead its reorganization towards the 2028 polls.
The General Secretary position is considered one of the most influential in the party’s administrative structure, responsible for the day-to-day running of the party secretariat and implementation of party decisions.

UGMC disputes Michael Blackson’s claims over late mother’s treatment

The University of Ghana Medical Centre (UGMC) has disputed claims made on social media by comedian Michael Blackson concerning the treatment given to his late mother, saying a review found that the allegations did not accurately reflect what happened during her stay at the hospital.
In a statement issued in Accra on August 5, 2026, the management of UGMC expressed condolences to Mr. Blackson and his family over the death of his 83-year-old mother, who died at the facility on July 16, 2026.
The hospital said it had taken the concerns raised by Mr. Blackson seriously and conducted a thorough review in line with its clinical and administrative procedures.
According to the statement, the facts presented by Mr. Blackson on social media contained “numerous inaccuracies” and did not accurately reflect the medical care provided to his mother.
UGMC explained that she was referred to the facility from another hospital and received treatment there from May 27 to July 16, 2026, a period of about eight weeks.
The hospital stated that it would not release details of her diagnosis, treatment, medical records or other aspects of her care because it had a duty to protect patient confidentiality, even after death.
It said the decision was intended to respect the dignity of the deceased and the privacy of her family.
UGMC further stated that all clinical decisions at the facility are made by qualified healthcare professionals based on medical judgment, established standards of care and the best interests of the patient.
The statement added that such decisions are made in consultation with authorised family representatives where necessary and that billing and financial procedures are governed by institutional policies and are separate from clinical decision-making.
The hospital noted that it values feedback from patients and their families and considers both positive and negative comments important for improving the quality of care.
Mr. Blackson had earlier used social media to criticise the care his mother received at UGMC, prompting the hospital’s response.
