Coronavirus: Oxford vaccine triggers immune response
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.

The Ashanti South Regional Police Intelligence Directorate has arrested two suspects in connection with a robbery attack on an Indian national in Obuasi and a separately planned robbery operation targeting a distribution company in the same area.
On April 16, 2026, Police received credible intelligence that a group of armed men were planning an attack in Obuasi. A police team moved swiftly into the area and arrested suspect Iddrisu Fuseini, also known as “Iddi”, at his hideout in Bedieso, Obuasi.
During interrogation, he confessed to being part of a six-member gang that attacked an Indian national at his residence at New Baakoyeden, Obuasi, on April 12 2026, robbing him of GH₵150,000.00.
He disclosed that the attack was orchestrated following a tip-off from suspect Ibrahim, an employee of the victim, who informed the gang that the victim kept large sums of money.
Further investigations led to the arrest of a second suspect, Shaibu Mohammed, also known as “SM” or “Cicinati”, on 20th April 2026 at his hideout in Gausu, Obuasi. During interrogation, he admitted to participating in the planning of the robbery and confirmed that the gang had further planned to rob a distribution company near Mawuli Hotel in Obuasi.
Investigations have further revealed that both suspects are currently standing trial at the Obuasi Circuit Court in connection with a separate robbery of GH₵600,000.00.
A manhunt is ongoing to arrest the remaining accomplices, identified as Khalifa, Edward, Prof, Waddle, Ebbe, and Ibrahim, and to recover a pump action gun and a locally manufactured pistol believed to be in their possession.
The Inspector-General of Police (IGP), Mr. Christian Tetteh Yohuno, together with members of the Police Management Board (POMAB), on April 17, 2026, decorated nineteen (19) senior officers who have been promoted to their next ranks based on the recommendations of the Police Council and approval of the President, John Dramani Mahama.
The ceremony, held at the National Police Headquarters in Accra, forms part of efforts to recognise merit, dedication, and long-standing service within the Ghana Police Service, while strengthening leadership across key operational and administrative levels.
The officers promoted from Deputy Commissioner of Police (DCOP) to Commissioner of Police (COP) are Dr. Luke Asue-In-Yeng Zakpaa, Mr. Frederick Agyei, Mr. Duuti Tuaruka, Mr. Arthur Osei-Akoto, Mr. Darko Offei Lomotey, Mr. Eric Ken Winful, Mr. Barnabas Nambont Nasumong, and Mr. Desmond Owusu Boampong.
The IGP and members of POMAB congratulated the officers and urged them to uphold the highest standards of professionalism and integrity in the discharge of their duties.
