The early symptoms of Covid-19 are not always easy to distinguish from the possible side effects of coronavirus vaccines, so people with Covid-19 symptoms after vaccination should stay home and do test, according to scientists in Britain.
The researchers, led by Professor Emma Duncan of King’s College London, published their findings in the journal eClinical Medicine, analyzing data on 362,770 people who had been vaccinated with AstraZeneca or Pfizer / BioNTech. of the ZOE Covid Study App – at least one Covid-19-related symptom within the first week after vaccination. Of these, 14,482 had a molecular or rapid test and finally 150 were positive for coronavirus (usually without typical Covid-19 symptoms such as persistent cough or loss of smell / taste but only more common symptoms such as fatigue, myalgia or headache). .
To distinguish between those with early Covid-19 symptoms and those with Covid-19-like vaccine side effects, the researchers used an artificial intelligence system, but even “smart” models could not tell the difference. According to the researchers, there was no way – unless a diagnostic test was performed – to distinguish a doctor if symptoms such as fever, headache, fatigue, muscle aches, etc., were due to the vaccine or Covid-19 infection. initial stage.
The scientists pointed out that as the cases increase again, due to the new Omicron variant, it is important not to confuse the symptoms due to vaccination with those due to infection, taking into account that the immune protection of vaccines takes time to develop in the body.
As Dr. Duncan said, “Vaccination remains extremely important to protect yourself, your family and your community from Covid-19. But if you have symptoms after the vaccine, you should not assume that it is just a side effect. You should check with a vaccine to make sure you do not have any initial symptoms of Covid-19. It takes time to develop immunity after vaccination. You know this for your own good and for the good of other people, so make sure you do not transmit the virus, especially to vulnerable people. the spread of Covid-19 “.
