Coronavirus: UK confidence in the safety of the Covid vaccine has risen despite fear of a blood clot


A poll shows that people in the UK now have more confidence in the safety of Covid vaccines than they did before blood clotting concerns across Europe.

The number of people wanting an injection has risen as soon as possible, with 46 percent saying they are sure they will progress – up from 36 percent in December.

A public survey by Bristol and Kings College London found that people are more likely to believe that vaccines increase the risk of blood clots, but still want them anyway.

About one in three people (31 percent) still believe the link is correct – even after the UK medical regulator moved to recommend that the vaccine should not be used on people under the age of 30 due to the potential risks.

However, AstraZeneca’s reputation jab took a hit with a fiasco. Only 17 percent said they would choose AstraZeneca if given the option, down from 24 percent in March.

In a major advance in providing vaccines to members of ethnic minorities, who were more likely to reject the vaccine, the proportion of people who said they would receive the vaccine once it was introduced has doubled three times in the past four months to 45 percent.

Professor Bobby Duffy, who conducted the survey, said that fear of a blood clot “did not reduce confidence in vaccines.” “In fact, the trend has been toward increasing adherence to vaccination – and fast.”

An increasing percentage of people said they would get an injection as soon as possible

The study asked 4,896 UK adults, ages 18 to 75, who were questioned between April 1 and 16.

The UK Medicines Regulatory Authority, MHRA, announced on April 7 that it is changing its advice to avoid recommending AstraZeneca dosage for those under 30.

After reports of rare blood clots in people along with low platelet levels, experts determined that the vaccine appeared to increase the risk.

In some cases, people have developed a condition called CVST – cerebral venous sinus thrombosis – which causes clots near the brain and can lead to strokes if left untreated.

Since this was seen so often in young men, although it was still at a rate of about 1 in 200,000, the MHRA decided to give a different vaccine under the age of 30 to be on the safe side.

Some countries in Europe stopped using acupuncture altogether or had an upper age limit, and refused to give it to anyone other than the elderly, for example. But there is still no evidence that vaccines are causing the problem.

Professor Duffy said: “ Fear of a blood clot has influenced some public’s perception of the AstraZeneca vaccine – but it has not diminished confidence in vaccines in general.

In fact, the trend was toward increasing adherence to vaccination – and rapidly – as the vaccination process progressed well, with no sign of serious problems on a large scale.

Q&A: Everything you need to know about COVID vaccines and blood clots

Is there any evidence that the vaccine causes blood clots?

Scientists have repeatedly insisted that there is no evidence yet that coronavirus vaccines cause extremely rare complications – blood clots that occur alongside low platelet levels.

But officials are still investigating the link – found in AstraZeneca and Johnson and Johnson vaccine recipients – and can’t rule it out completely.

Do scientists have a theory about what the link might be?

Experts are puzzled as to why vaccines cause blockages so rarely.

But one acquired explanation is that it might be due to an overreaction in the immune system, causing the body to attack its own platelets – small pieces of cells within the blood that build clots to stop bleeding when someone is infected.

Experts believe that acupuncture can cause the body to produce antibodies – commonly used to fight viruses – that mistake platelets in the blood of foreign invaders and attack them.

To compensate, the body then overproduces platelets to replace those that are under attack, resulting in thicker blood and an increased risk of clotting. This then causes the platelet levels to drop.

Researchers say this phenomenon is similar to that which can occur in heparin-induced thrombocytopenia (HIT), when a patient takes a drug called heparin.

What symptoms does it cause?

The EMA said symptoms can appear for up to three weeks after vaccination.

British organizers say complications tend to occur four days after people are stabbed.

Symptoms of blood clots can include:

  • Shortness of breath
  • Source
  • Swollen legs
  • Persistent stomach pain
  • Severe or persistent headache
  • Blurred vision
  • Confusion
  • Seizures
  • Skin bruising outside the injection site

People have had more time and real-world experience to help them make their decisions.

However, it also means that skeptics have naturally confirmed their views as well, with nearly doubling since July of last year – from seven percent to 13 percent – of those who say they are not likely at all or certainly will not. They do that. Get vaccinated.

This shows that there is still no room for complacency in clearly communicating the vital benefits of vaccination, given the need to cover a very large proportion of the population in order to truly contain the virus.

The survey found that the number of people who believed the AstraZeneca vaccine would cause blood clots increased from 17 percent to 31 percent after the Ministry of Health and Population announced.

People who were already concerned about punches were more likely to believe it – 57 percent – but the majority of people still said the alleged link was either wrong or they didn’t know.

Despite this, the percentage of people who say they believe vaccines are safe has risen.

In the survey, 81 percent of people said they think vaccines are safe, compared to 73 percent at the end of 2020. This includes 39 percent of those who strongly agree that this is the case – up from 30 percent.

And more people were convinced of their effectiveness – 86 per cent said they believed the cookies to be effective, compared to 79 per cent in December.

The researchers said there has been a “significant change” in the number of ethnic minorities who want a jab.

Experts and ministers were concerned about the low turnout in non-white communities and made efforts to try to convince them that it was safe and correct to get a jab.

The study found that 45 percent of those belonging to ethnic minorities now say they will get vaccinated upon their call, which is up from 15 percent before it began last year.

Dr Sioban McCandro, a sociologist at the University of Bristol, said: “ These findings shed light on different aspects of the reluctance to be vaccinated against the Coronavirus: concerns about long-term side effects, efficacy of the vaccine, vaccine components, and the effectiveness and speed of regulatory clearance. .

These concerns persist for a hard core of the opposing vaccine.

The public health challenge remains complex: responding to the information concerns and needs of a diverse population, supporting the social base in favor of the vaccine, and providing meaningful reasons for taking the vaccine to those who remain unconvinced.

University of Cambridge epidemiologist Dr. Ragheb Ali told MailOnline yesterday that younger adults should get their vaccinations to end the lockdowns, even if they are less likely to die.

The NHS vaccination program has opened up to people in their late 40s, with everyone over the age of 44 now eligible for an injection that can be booked online or over the phone, and is expected to expand to include people in their 30s next week.

But experts are concerned that younger people will have less mass absorption than older adults because they do not have a high risk of dying from Covid, and they may be more likely to see anti-vaccination theories online or be concerned about side effects.

Dr Ali said: “ We will face a problem, especially among young people who realize that the risk of Covid will be lower.

I would say to these people, if you want to avoid another lockdown, vaccination is the best way to do it. Young people suffer the most from lockdown due to their mental and economic health. Vaccination is the only way to do this.

The possibility of blood clots forming after covering them after the vaccine

A study found that people are up to 10 times more likely to develop a blood clot in the brain after contracting Covid compared to after getting a vaccine.

Cerebral venous sinus thrombosis is a condition that has spooked regulators by appearing in recipients of AstraZeneca or Johnson & Johnson.

But researchers at Oxford University claim that the risk of complications is significantly higher after infection with the Coronavirus than it is after receiving any of the Covid strikes.

They insist that the benefits of vaccination are much higher than the risks, because the chance of getting a clot is still extremely rare, and a comprehensive vaccination will protect millions of people – those who get vaccinated and the people around them.

Scientists studied data from the United States to see how many times people were diagnosed with CVST after testing positive for coronavirus.

They estimated the rate was 39 cases per million people – 0.0039 per cent, or one in 25,641.

The rate of people who got the Pfizer or Moderna vaccine was about four in a million – 0.00039 percent or one in 250,000.

Based on European data, they said the risk after the AstraZeneca strike looked roughly five in a million – 0.0005 percent or one in 200,000.

“ The main message is that the risk of this particular event is actually much lower than if you had Covid or someone else had Covid, ” said Dr. John Geddes of the university’s Biomedical Research Center.

The study came after another Oxford University professor not involved in the research, Sir John Bell, said the risk of blood clots after vaccination was “negligible”.

The Oxford study calculations indicated that the CVST rate is 39 per million among people who test positive for Covid-19, compared to four to five people per million after vaccination.
