Early Covid symptoms are no different to minor side effects from vaccines and people who develop a headache or fever after their jab should get tested, experts say

  • Study finds early covid symptoms like headache and fever may be mistaken for vaccine side-effects
  • Scientists say the virus may have been spread by recent jabbeds, thinking his symptom was from the vaccine
  • Researchers urge Jabbed not to make assumptions and get a COVID test done to help keep other people safe
  • The study was based on data submitted by 362,770 people who did their jobs from December to May last year
  • Fears of impact of Omicron variant spark findings as UK cases and vaccine drive rise

Scientists have warned that some of the side effects of the Covid jab are almost indistinguishable from the initial symptoms of the virus.

Researchers fear it could unintentionally spread the coronavirus to people, and say people who become ill after taking the jab should be isolated and tested.

Vaccines do not provide immediate protection, it takes up to two weeks for the body to learn how to fight the virus. Still, if they do catch it, they can’t stop people from getting symptoms of the virus.

One in 10 people may experience side effects after the jab, including headache, tiredness, and fever. Experts at King’s College London say that these side effects are also early warning signs of Kovid.

Although UK guidance only officially recognizes three symptoms of COVID, surveillance studies have suggested it causes dozens.

Academics found 1 percent of people reporting symptoms after the jab were actually positive.

Professor Emma Duncan said: ‘Vaccination is extremely important to help protect yourself, your family and your community from COVID.

‘However, if you have symptoms later, you should not assume that this is just a side effect of vaccination, although fortunately this was the most likely outcome.’

The alert is timely, with the UK currently launching a massive COVID booster programme. Cases of the virus are on the rise in the UK as well, fueling fears that the Omicron variant is already taking hold in the community.

This chart shows the symptoms reported by vaccinated people in the seven days after receiving the vaccination. The orange bars show the symptoms of those who tested positive for Covid, while the teal shows the symptoms of those who tested negative. This shows that in most cases the symptoms were very similar between the groups and there is no way to tell whether a person is COVID positive or suffering from side effects of the vaccine without testing. A* indicates a trait for which there was a statistical difference

The research, part of the ZOE Covid Study, examined data from 362,770 people in the UK who were vaccinated between 8 December and 17 May and who reported at least one possible COVID symptom in the days after being vaccinated Was.

Out of this group, 14,842 people took a Covid test with 150 later testing positive for the virus.

What are some common side effects of covid vaccine?

Like all medicines, the COVID vaccine can cause side effects, but not everyone gets it.

Most side effects are mild and should not last longer than a week, such as:

  • injection arm pain
  • feeling tired
  • Headache
  • I’m liking it
  • feeling sick or sick

You may also have a high temperature or feel hot or shivering for a day or two after your vaccination. If needed, you can take pain relievers like paracetamol. If your symptoms get worse or you are concerned, call 111.

If you have a high temperature that lasts for more than two days, a new, persistent cough, or a decrease or change in your sense of smell or taste, you may have COVID. Stay at home and get tested.

You cannot catch COVID from the vaccine, but you may have caught it just before or after your vaccination.

After examining the data, the scientists published their findings in the journal e-Clinical Medicine, said there was no way to tell whether the symptoms people reported were from covid or a side effect of the jab, until a test was done.

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

‘This is especially important now, when the UK is experiencing high levels of infection in the community and especially as we are still learning about the new variant, Omicron.’

He said it was important to remember that vaccines take time to work, and urged people to be responsible to others and get tested.

Professor Duncan said: ‘It takes time to develop immunity after vaccination; And it’s important to know if you’re infected—both for yourself, so you can receive proper care, and for other people’s sake, so that you can make sure you don’t pass it on to vulnerable individuals.

‘Getting tested if you have symptoms – even if you have been vaccinated – will help prevent the spread of COVID.’

The scientists did not say whether their findings differed by the type of vaccine received.

People can get a free PCR COVID test if they are experiencing a high temperature, a new persistent cough, or a decrease or change in their sense of taste or smell, the classic symptoms of a COVID infection.

The NHS says some of the most common side effects of having a COVID jab are pain, fatigue, aches and pains in one arm at the injection site, and feeling or being sick.

People can also get a temperature in the days immediately following their jab, with the NHS recommending anyone whose temperature does not disappear after two days to self-isolate and undergo a COVID test.

The study’s findings come at a time of both rising COVID cases and increasing focus on vaccination.
