WHAT ARE THE SYMPTOMS OF THE RARE BLOOD CLOTS LINKED TO ASTRAZENECA’S VACCINE?
- Shortness of breath
- Chest pain
- Swelling of leg
- Persistent stomach pain
- Severe headache
- Blurred vision
- Skin bruising beyond the site of injection
MHRA chief executive Dr June Raine said anyone who has one or more of the above symptoms for longer than four days after vaccination should seek urgent medical advice.
Britons under 30 should be offered an alternative to AstraZeneca’s coronavirus vaccine due to mounting evidence linking it to rare blood clots, UK health chiefs ruled today.
In a blow to the UK’s vaccination rollout, the Government’s vaccine advisory group is recommending healthy people aged 19 to 29 be offered either the Pfizer or Moderna jabs instead when the programme moves to younger groups in the coming months.
Anyone who has already had their first dose of the AstraZeneca vaccine, regardless of their age, is being advised to go for their second appointment as planned.
A review by the drugs watchdog the MHRA found that by the end of March 79 out of 20million Britons vaccinated with the AstraZeneca vaccine had suffered deadly blood clots in the brain or arteries, a rate of about one in 250,000. Nineteen of the cases died and three were under the age of 30.
The MHRA insisted there was still no concrete proof that the British-made vaccine is causing the clots, but admitted the link was getting firmer. The review prompted the Government’s vaccine advisory group, the JCVI, to recommend that people aged 18 to 29 be given an alternative jab.
Britons over that age are still being advised to get the vaccine because the risk of Covid far outweighs the chance of developing the extremely rare conditions. But the JCVI said the benefit to risk ratio was ‘more finely balanced’ in younger people.
England’s deputy chief medical officer Profess Jonathan Van-Tam said the new advice marked a ‘course correction’ for the UK’s rollout – and reiterated that for the vast majority of people the ‘benefits outweigh the risks’. He insisted the move would have no bearing on the UK’s ambition to vaccinate all adults against coronavirus by the end of July, so long as Pfizer and Moderna can meet their scheduled deliveries.
Announcing the updated guidance today, Dr June Raine, head of the MHRA, told a press conference: ‘Based on the current evidence, the benefits of the Covid-19 vaccine AstraZeneca against Covid-19 and its associated risks – hospitalisation and death – continues to outweigh the risks for the vast majority of people. Our review has reinforced that the risk of this rare suspected side effect remains extremely small.’
Meanwhile, the European Medicines Agency’s safety committee was more restrained and said blood clots should be listed as a ‘very rare side effect’ of the jab. It is not recommending that EU countries restrict its use in any age groups yet until the link has been properly established.
Prime Minister Boris Johnson said the Government believes the Oxford/AstraZeneca vaccine is ‘safe’, telling reporters on a visit to Cornwall: ‘But the crucial thing for everybody is to listen to what the scientists, the medical experts have to say later on today.’
He added on the vaccination programme: ‘You can really start to see some of the benefits of that – it’s pretty clear that the decline in the number of deaths, the decline in the number of hospitalisations is being fuelled, is being assisted, the steepness of that decline is being helped by the rollout of the vaccines so it’s very important for everybody to continue to get your second jab when you’re asked to come forward for your turn.’
More than 20 million doses of the AstraZeneca vaccine have now been given in the UK, saving an estimated 6,000 lives.
Jonathan Van-Tam, England’s deputy medical officer, led a press conference this afternoon, where it was announced the AZ vaccine is being restricted in under 30s
The Government wheeled out a series of graphs comparing the risk of falling ill with Covid compared to the threat of developing blood clots after getting the AZ vaccine in various age groups. It used three different scenarios, showing the risk when there is a large (shown), medium and small epidemic
When there is medium prevalence, the threat of Covid still outweighs the chance of clots after AZ vaccine in every age group
But when the virus is petering out – as it is currently in the UK thanks to the vaccines and brutal lockdown – people under 30 are more at risk of being seriously harmed by the vaccine than falling severely unwell with Covid

- One in three Covid survivors are diagnosed with anxiety, depression or other mental health issues within six months of recovering, major study finds;
- Generation of home-schooled children lacked ‘discipline and order’ in lockdown says Gavin Williamson as he backs mobile phone ban in schools.
Professor Van-Tam acknowledged the change in recommended use of the AstraZeneca vaccine might result in delays and longer journeys to receive the jab.
He told a press conference: ‘The NHS has a message that we will get the right vaccine to you in the right time according to the new JCVI advice.
‘There might be a small delay sometimes, there might be a slightly greater distance that some people might be asked to travel.
‘But the NHS is all over this and understands the challenge of making the advice from JCVI truly operational in a smooth way.’
Of the 79 people who suffered clots after getting the AstraZenca vaccine in the UK, a total of 19 people have died, although it has not been established what the cause was in every case. The 79 cases occurred in 51 women and 28 men, aged from 18 to 79. Of the 19 who died, three were under the age of 30, the MHRA said.
Some 14 cases of the 19 were cerebral venous sinus thrombosis (CVST), a specific type of clot that prevents blood from draining from the brain. The other five cases were thrombosis in the arteries.
Professor Van-Tam pointed to a series of graphs showing that for the vast majority of people, the risk of falling unwell with Covid far outweighed the chance of developing blood clots from the AZ vaccine.
Leaked delivery schedules reveal the Government is expecting AstraZeneca’s vaccine to make up 75 per cent of its Covid jab supplies over the next two months. The document, published on the Scottish Government’s website in January and quickly taken down, showed Britain was anticipating about 29.4m doses of AstraZeneca’s jab between April and the first week of June. By comparison, officials expected just 8.5m of Pfizer’s vaccine in the next two months and 1m of the new Moderna jab, which is being rolled out for the first time in Wales today
People are still being encouraged to have the AstraZeneca jab and yesterday Boris Johnson (pictured exercising today) said it was ‘very very important’ the public go for their inoculations
Elle Taylor, 24, today became the first person to receive the Moderna jab in the UK. She said it would help her care for her grandmother ‘properly and safely’
WHAT ARE THE BLOOD CLOTS LINKED TO ASTRAZENECA’S VACCINE AND WHAT SYMPTOMS DO THEY CAUSE?
WHAT ARE THE BLOOD CLOTS LINKED TO ASTRAZENECA’S JAB?
European health chiefs today ruled that AstraZeneca’s Covid jab should come with a warning that, in very rare cases, it may cause potentially deadly blood clots.
The EMA, which polices the safety of drugs used on the continent, spotted 169 cases of cerebral vein thrombosis (CVST) and 53 cases of splanchnic vein thrombosis (SVT), from 34million jabs.
CVST occurs when a vein that drains blood from the brain is blocked by a clot. It can lead to a stroke.
SVT is the same type of blood clot but it occurs in the digestive system.
WHAT SYMPTOMS DO THEY CAUSE?
The EMA said symptoms of the two blood clots included:
- Shortness of breath
- Chest pain
- Swelling of leg
- Persistent stomach pain
- Severe headache
- Blurred vision
- Skin bruising beyond the site of injection
IS THERE ANY PROOF THE JAB CAUSES THE BLOOD CLOTS?
Scientists have repeatedly insisted there is no proof yet that AstraZeneca’s coronavirus vaccine causes the blood clots.
But officials are still investigating the link and can’t rule it out completely.
Although there isn’t any evidence that the clots are developing because of vaccinations, some academics have a theory that it is the immune reaction making it happen.
Research teams in Germany and Norway claim the blood clotting issue may be caused by the jab, in very rare cases, making the body attack its own platelets.
Platelets are tiny chunks of cells inside blood that the body uses to build clots to stop bleeding when someone is injured. But they can also make unwanted clots.
Experts from Oslo and Greifswald University believe the jab could cause the body to produce antibodies – normally used to fight off viruses – which mistake platelets in the blood for foreign invaders and attack them.
To compensate, the body then overproduces platelets to replace those that are being attacked, causing the blood to thicken and raising the risk of clotting.
The researchers say the phenomenon is similar to one that can occur in heparin-induced thrombocytopenia (HIT), when sufferers take a drug called heparin.
HOW OFTEN ARE THE CLOTS OCCURRING?
Figures presented by the EMA today — which took into account data up until April 4 — suggested the clots were occurring once in every 150,000 jabs. They also said most of the cases had occurred in women under 60.
The MHRA, which plays the same role in the UK, found 79 cases of clots in 20million doses by the end of March.
Officials said the risk was around one in every 250,000 doses.
They also insisted the benefits of the vaccine outweigh the risks for the vast majority of people — but that the ratio was more ‘finely balanced’ in younger people.
EMA chiefs said that the clots were occurring more often than expected, prompting them to say the jabs need to come with the warning that it is a rare side effect.
But it said the committee investigating the link did not conclude that age and gender were clear risk factors for the very rare side effects.
WHICH COUNTRIES HAVE ALREADY RESTRICTED THE JAB TO OLDER PEOPLE?
Germany last week temporarily banned the AstraZeneca vaccine for under-60s, while France took the same controversial move for under-55s.
Iceland has restricted it to over-70s, while Finland, Sweden and Lithuania all say it can only be given to adults over the age of 65.
Denmark, Norway, the Netherlands and Latvia have all suspended the jab completely, while regulators probe the link further.
But the EMA refused to back any of the nations in their age-restricted roll-outs. Last week it publicly said there was no evidence to justify sweeping bans for younger people.
WHAT DOES BRITAIN’S DECISION MEAN?
The MHRA ruled that Britons under 30 should not be given AstraZeneca’s coronavirus vaccine due to mounting evidence linking it to rare blood clots.
More than 20million doses of the AstraZeneca vaccine have now been given in the UK, with the jab used as the main weapon in the UK’s arsenal.
The roll-out is unlikely to move on to under-30s for several weeks, perhaps months, meaning that supplies of the other jabs could be saved for younger adults.
But, given that AstraZeneca’s vaccine is the main driver of the campaign, the roll-out could be slowed if the change of heart on blood clots knocks public confidence in 30-50 year olds.
He explained: ‘If you look at the 20 – 29 age band then the potential benefits amount to 0.8 serious ICU admissions prevented, compared to serious harms of potentially 1.1.
‘But as you go up through the age groups the amount of serious harms declines but the amount of benefit in terms of inverted ICU admissions becomes much more pronounced.
‘You can see at a lower exposure risk – lower than we have in the UK at the moment – it is relatively finely balanced in those younger age groups, but it becomes fairly overwhelmingly in favour of vaccines as you go down the ages.’
On the medium prevalence slide of 60 cases per 100,000 – higher than the UK’s 41.4 current rate, he added: ‘You can see that as the virus is around us more the potential benefits of being vaccinated continue to stack up, but the risks from vaccines remain static of course. You can see the data become more overwhelming in terms of vaccine benefit.’
Pointing to a chart showing Covid levels similar to the height of the second wave, he added: ‘But here where there is a lot of Covid circulating in the population you can see that even in the 20 to 29 group the potential benefits in terms of care admissions averted is much higher compared to the risks of vaccine, and that is why regulators have concluded as they have in terms of risk benefit about the AstraZeneca vaccine.’
Vaccines minister Nadhim Zahawi tweeted that there was ‘reassurance’ that drug safety standards worked well ‘in both the United Kingdom & the EU’.
He added: ‘This is important in maintaining confidence in the largest vaccination program in history. As @BorisJohnson has said; We will follow the advice & are confident in meeting our programme targets.’
Professor Van-Tam insisted that the MHRA’s updated guidance would not impact Boris Johnson’s roadmap out of lockdown, which will see restrictions lifted fully on June 21.
Any stall of the vaccine roll-out would be a political body blow to Boris Johnson who has enjoyed a recovery in the polls thanks to his success deploying jabs after a series of missteps at the start of the pandemic.
The UK’s drive has already been thrown into crisis, with NHS bosses effectively blocking over-40s from getting jabs this month following India’s decision to block a shipment of 5million AstraZeneca doses that officials hoped would speed up the roll-out.
Officials have put the AstraZeneca jab at the heart of the country’s rollout and the leaked delivery schedule reveal the Government is expecting it to make up 75 per cent of its Covid vaccine supplies over the next two months.
The document, published on the Scottish Government’s website in January and quickly taken down, showed the UK was anticipating about 29.4million doses of AstraZeneca’s jab between April and the first week of June.
For comparison, officials expected just 8.5m of Pfizer’s vaccine — which is already being rationed for second doses — in the next two months. Britain’s supply comes entirely from the EU, which has threatened to block exports of the jab.
Officials were also only expecting 1million doses of the new Moderna jab, which is being rolled out for the first time in Wales today. But supply will trickle in at around 160,000 doses a week, if the leaked plans are still correct. And the UK has only bought 17million – enough to vaccinate 8.5million people.
Professor Adam Finn, from the University of Bristol and a member of the Government’s vaccine advisory group, the JCVI, admitted pausing the AstraZeneca jab could threaten Britain’s roadmap out of lockdown.
He said today: ‘We do need to keep the programme going if the plan to open things up and allow things to get back to normal is to proceed without another wave of the pandemic coming through. So it’s quite a tricky balancing act here, getting the balance right, getting vaccines coming through… getting the risk-benefit right for people coming forward.’
One Tory MP told MailOnline that halting the jab would ‘certainly put things back’, adding: ‘Clearly it would have very adverse consequences because AstraZeneca is the workhorse of the vaccination programme.’
However, the UK inoculation programme could be bolstered if two other promising jabs under review are given approval by the UK Medicines and Healthcare products Regulatory Agency in the coming weeks.
The chief scientist behind the US-developed Novavax vaccine, which Britain has secured 60million doses of, has said he expects it to be given the green light this month and rolled out in May. All of the Novavax supplies on order will be manufactured within the UK under a new Government deal announced last week, which could drastically speed up its distribution.
A separate vaccine made by American pharmaceutical giant Johnson and Johnson, which uses the same type of technology as AstraZeneca’s but is administered via a single injection, is slated for a summer rollout. Because people given the J&J vaccine don’t need a 12-week follow-up appointment, it means ministers don’t have to reserve supplies for second doses and can unleash them all at once.
MHRA sources originally said it would be ban for under-30s, which wouldn’t pose as much damage to roll-out. But there are fears that any ban could dent public confidence.
Britain’s inoculation drive drastically slowed down over the Easter weekend, figures show. Just 100,000 vaccines were dished out on Sunday and Monday, reaching 88,000 Britons.
