Scientists warn that some side effects from the Covid jab can be almost as severe as the early signs of the virus. 

Researchers fear that it could lead to inadvertently spreading coronavirus. They recommend people isolate any symptoms they experience and have their blood tested.

The body may take up to 2 weeks to develop immunity to the virus. Vaccines are not effective in providing immediate protection. Even then, vaccines may not prevent people from getting the symptoms of the disease if they get it. 

Side effects can include headaches, fatigue and fever. These side effects, according to experts at King’s College London, are early indicators of Covid.

While Covid can only be officially recognized in the UK, there have been surveillance studies that suggest it may cause dozens of other symptoms. 

According to academics, 1 percent of those who had symptoms after receiving the jab were actually positive.  

Professor Emma Duncan stated that ‘Vaccination is still extremely important to protect you, your family and the community against Covid. 

‘However, if you do have symptoms afterwards, you should not assume that it’s just side effects of the vaccination although fortunately this was the most likely outcome.’

With the UK embarking on an extensive Covid booster programme, this warning is timely. There are increasing cases of the Omicron virus in Britain, which raises concerns about its spread in the country.

This chart shows the symptoms reported by vaccinated people in the seven days after they received their jab. The orange bars indicate the symptoms of those who tested positive for Covid, while the teal shows the symptoms of those who tested negative. It shows that in most cases the symptoms between the groups were very similar and there is no way to tell if a person is Covid positive or suffering a vaccine side-effect without a test. A * indicates a symptom for which there was statistical difference

The chart below shows symptoms that people who were vaccinated reported within seven days of receiving their vaccine. The symptoms for those with positive Covid results are indicated by the orange bars, and the negative symptoms are shown in the teal. This shows that the majority of the cases were similar, and it is impossible to determine if someone is Covid positive or is suffering from a side effect.

Part of the ZOE Covid study, the research examined data from 362,770 UK citizens who had been vaccinated in December 8 to May 17. All reported having at least one possible Covid sign within the first few days.   

14.842 of these people completed a Covid testing, and 150 were later confirmed positive.

What are the most common side-effects of Covid?  

Covid vaccinations, like all drugs, can have side effects. But not everybody gets them.

Side effects of most medications are not severe and usually last less than seven days.

  • An injection can cause a stiff arm.
  • Tiredness
  • A headache
  • Feeling achy
  • feeling or being sick

One or more days following your vaccination, you may experience a fever or become hotter or shivier. Paracetamol and other painkillers are available if necessary. If you are worried or experiencing worsening symptoms, dial 111.

Covid is a condition where you experience a prolonged high temperature, an inability to smell and taste well, or have a persistent, hot, uncomfortable cough for more than 2 days. Take a blood test at home.

Covid cannot be contracted from vaccines, however you might have had it shortly before or after vaccination.

After examining the data the scientists, who published their findings in the journal eClinical Medicine, said there was no way to tell if the symptoms people reported were from Covid or a side effect of the jab, unless a test was taken. 

Professor Duncan said: ‘You should check to make sure you don’t have early Covid, by getting tested.

“This is especially relevant now that the UK has high levels infection in its community, and while Omicron is still being discovered.

Additionally, she stressed the importance of vaccines taking time to get to work and encouraged people to take responsibility for their actions and have a test. 

Professor Duncan said: ‘It takes time to develop immunity after vaccination; and if you are infected it’s important to know this – both for your own sake, so that you can receive appropriate care, and for the sake of other people, so that you can ensure you don’t pass it along to vulnerable individuals.

‘Being tested if you have symptoms – even if you’ve been vaccinated – will help stop the spread of Covid.’  

Scientists did not comment on whether their results were different depending upon the vaccine type.  

If you have symptoms such as a high fever or a persistent cough, a PCR Covid test can be performed for free.

According to the NHS the most common side effects from a Covid jab is a sore elbow at the site of injection, fatigue and aches and pains.   

A person can take a temperature within a few days of their jab. The NHS advises anyone who does not feel better after two days that they self-isolate to get a Covid test.

These findings are coming at a time when Covid cases have been on the rise and vaccination is being emphasized more. The Government plans to give a third dose of vaccines to all eligible adults by January 31st.

Yesterday, the Department of Health registered 51,459 Covid new cases. This is five more than on Monday. It also marks the third week in which figures surpass the 50,000 mark. 

There are fears the Omicron super-mutant Covid variant could have an effect on increasing cases. 

Top epidemiologist Professor Tim Spector has claimed cases of the highly evolved variant were doubling every two days and that there were up to 2,000 infections already — six times more than the official count because only a fraction of tests are currently being thoroughly analysed. 

There have been only 336 official Omicron cases confirmed in the UK so far, but there are likely more than a thousand already, according to Professor Paul Hunter, an epidemiologist at the University of East Anglia

According to Professor Paul Hunter (an epidemiologist at University of East Anglia), there have only been 336 Omicron cases in the UK. However, it is likely that more than one thousand Omicron cases are already confirmed.

This is the image that has sparked fear among scientists, prompted ministers to turbocharge the UK's booster vaccine rollout and seen the return of mask mandates in England. It details the new super-mutant Omicron variant's 32 spike protein mutations which experts fear will make it the most infectious and vaccine-resistant strain yet. The graphic, released by the country's top variant monitoring team, also lays bare how it is far more evolved than even the world-dominant Delta strain, with nearly five times as many alterations on the spike

This image has caused fear in scientists and prompted ministers at the UK to accelerate the rollout of booster vaccines. In England, mask mandates have returned. The graphic details 32 mutations in the spike protein of the Omicron super-mutant Omicron Omicron strain, which experts believe will lead to it being the most dangerous and resistant strain ever. This graphic was released by the nation’s leading variant monitoring team. It also shows how the strain is more advanced than the Delta strain. There are nearly five times the number of modifications to the spike. 

Total Covid cases are rising fastest in London and the South East of England with most of the Omicron infections linked to travellers flying back into the UK

London is experiencing the highest number of Total Covid cases. Most Omicron infections are linked to returning travellers who have flown into the UK.

King’s College London’s scientist who oversees the largest Omicron-symptom-tracking program in the country, has estimated that Britain would have Omicron cases in the next 10 days than any other African countries. This means there is no need to restrict travel.

Yesterday No10 advised that this variant was spreading within the US in different regions. There is currently a 336-person official count, but no one has been hospitalized. A separate data set shows the strain may be responsible for 1 in 60 new cases.  

Scientists believe booster jabs will provide high protection against Omicron-related severe illness or death, even though vaccines are less effective in preventing it. 

No10 last week announced that the booster program will be increased to 500,000 jabs daily and that it will offer an additional dose of vaccine to every 53 million British adult by January. This is to protect against any incoming waves. 

But the scheme already appears to be stalling with just 290,000 delivered across Britain. On average, only 378,000 people are administered daily.

Even though ministers promise to give’steroids’, booster roll-out remains stalled 

 Britain’s turbocharged Covid booster campaign appears to be stalling, despite the Government pinning its hopes of warding off Omicron on the programme. 

Last week, officials promised that they would roll out’steroids’ to increase the delivery of the third dose to 500,000 per day and open the program to people under 40.

But, latest NHS data has shown that the UK is not even close to this goal. The UK actually delivers fewer booster shots than it did before Boris Johnson announced, some days ago. 

Only 290,165 boosters had been rolled out on Sunday (the day that the most recent data are available). The figure for the week before was 285,335.

On Saturday, 464,616 jabs were given. This was the closest roll-out came to the Government’s goal of half-million per day. However, this number was only slightly lower than that of the prior week’s 464,616 jabs. 

It will be March before every Briton eligible for the third Covid vaccine is offered to them. This pace of vaccination, which averages 2.7 million per week, puts it well beyond the government’s January deadline.  

Even though the Covid booster promises are bold, many elderly and vulnerable UK citizens still have difficulty getting one. Many of them have complained that they are unable to obtain an appointment or that the staff is too busy to help. 

This program is still being expanded for the younger age group, so it won’t open to all until next week. 

According to The Telegraph, officials have blamed the lack of acceleration on red-tape due to waiting for legal instructions on the roll-out to be provided by the UK Health Security Agency (UKHSA). 

 In total just over 20.5million Covid boosters have been administered across the UK.

These figures are less than half of what the 53 million chiefs of health hope to offer as a booster for the end-of-January.

The Telegraph received information from sources that said the NHS had delayed the opening of its booking systems while it waited for UKHSA to provide legal instruction.

Others argued that such paperwork shouldn’t cause delay because pharmacists, doctors and nurses can follow updated instructions to give boosters within three months. 

Non-medics, on the other hand, aren’t yet capable of doing so and will have to continue with the 6-month period.

NHS officials insist supply is not the problem.

A spokesperson for the NHS stated that the instructions would be updated by the UKHSA in order to reflect last week’s clinical guidance. The national booking system can then also be updated. This could not take place before 13 December, officials previously advised.
