![]() One study found signs of endothelial damage and fragments of SARS-CoV-2, including the spike protein, in the brains of 13 people who had died of Covid-19. There have been some studies showing that SARS-CoV-2 can damage endothelial cells, which line the blood vessels. Scientists who reviewed Dr Bridle’s claims for fact checker Health Feedback have described these assertions as misleading, as they “misrepresented the results from scientific studies and based on cherry-picked information”. Secondly, that the spike protein produced by the vaccine does not just act locally, at the site of the jab, but gets into the bloodstream and is carried to many other sites in the body. Firstly, that the spike proteins generated by the vaccine cause cardiovascular damage if they get into the bloodstream. Dr Bridle’s claimsĭr Bridle’s concern rests on two claims. The Covid-19 vaccines approved for use in the UK work by giving the body instructions on how to make the spike protein, so that if the person is later infected, their immune system can generate a response that attacks the virus (via the spike protein) faster and more effectively. This spike protein helps the virus enter cells and is also one of the ways the human body’s immune cells recognise a virus and attack it. Subscribe What is the spike protein and what has it to do with vaccines?Īs we have written before, there is a protein on the surface of the SARS-CoV-2 virus (the virus which causes Covid-19), called a spike protein. If indicated, a repeat test may yield more reliable results.Be first in line for the facts – get our free weekly email The most common reasons for equivocal results are presence of an immune response but unclear if against the infection being tested for (COVID-19 in this case) or similar infections (the common cold is a type of coronavirus). If you had symptoms consistent with COVID-19 within the past 3 weeks and tested negative, repeat testing in 1-2 weeks may yield a positive result.Įquivocal: Your test results could not be interpreted as Positive or Negative. Please note, it may take 14-21 days to produce detectable levels of IgG following infection. This means you have not been infected with COVID-19. Negative: You tested negative for COVID-19 IgG antibody. For patients testing higher then 2,500 U/mL, your results will be reported as “Greater Than 2,500 U/mL." ![]() Please note: A numerical value will be reported up to 2,500 U/mL. It is yet undetermined what Antibody level is correlated to immunity against developing the COVID-19 infection A negative result means your immune system has not generated a measurable response to the COVID-19 vaccination and that you have likely not had the COVID-19 infection. < 0.80 U/mL: This is a negative result for anti SARS CoV-2S. The test is not able to differentiate whether the antibodies produced were in response to the vaccine or to a prior infection. It may also mean your body’s immune system has generated a response to a prior COVID-19 infection. A positive result means your body’s immune system has generated a response to the COVID-19 vaccine. >/= 0.80 U/mL: This is a positive result for anti-SARS CoV-2S. ![]() Your Spike Protein Antibody results will be reported as a reference range:
