COVID-19 Vaccines Linked to Rare Disorders: Study Finds Increased Risk of Heart, Brain and Blood Conditions

COVID-19 vaccines have been linked to rare occurrences of heart, brain and blood disorders. A study published in the journal Vaccine found that COVID vaccines from companies like Pfizer, Moderna and AstraZeneca were associated with a slight increase in neurological, blood and heart-related medical conditions. The largest global vaccine safety study to date identified rare events early in the pandemic including a higher risk of heart-related inflammation from mRNA shots made by Pfizer Inc., BioNTech SE, and Moderna Inc., as well as an increased risk of a type of blood clot in the brain after immunization with viral-vector vaccines such as AstraZeneca's. The study also found that COVID was the leading cause of death amongst children from a disease caused by an infection in 2021, and it is critically important for children to get vaccinated against COVID as they were the leading cause of death from an infection caused by disease in 2021.

  • Unique Points
    • COVID vaccines from companies like Pfizer, Moderna and AstraZeneca have been linked to rare occurrences of heart, brain and blood disorders.
    • An increased risk was found of a type of blood clot in the brain from viral-vector shots such as AstraZeneca's.
  • Accuracy
    No Contradictions at Time Of Publication
  • Deception (30%)
    The article is deceptive in several ways. Firstly, it states that COVID vaccines have been linked to rare occurrences of heart, brain and blood disorders. However, the study only found a slight spike in neurological, blood and heart-related medical conditions after receiving these vaccines.
    • The article claims that COVID vaccines are linked to an increased risk of developing blood clots in the brain. However, it fails to mention that this condition is not considered a serious side effect by health organizations such as the CDC and WHO.
    • The article claims that COVID vaccines are linked to rare occurrences of myocarditis (inflammation of the heart muscle). However, it fails to mention that this condition is not considered a serious side effect by health organizations such as the CDC and WHO. The study found only 12 cases of myocarditis after vaccination out of over 99 million people.
    • The article states that COVID vaccines are linked to an increased risk of developing Guillain-Barre syndrome, a rare neurological disorder. However, the study found only one case of this condition after receiving AstraZeneca's viral-vector shot out of over 99 million people.
  • Fallacies (85%)
    The article contains several examples of informal fallacies. The author uses an appeal to authority by citing a study and experts without providing any evidence or context for their opinions. They also use inflammatory rhetoric when they describe the potential risks of COVID-19 vaccines as 'rare occurrences' and 'potential vaccine safety signals'. Additionally, the article contains examples of dichotomous depictions by describing the benefits and risks of COVID-19 vaccines in stark contrast to each other. The author also uses an appeal to emotion when they describe the potential harm caused by COVID-19 as being much more dangerous than any potential side effects from vaccination.
    • The study found that rare cases of myocarditis were found in the first, second and third doses of Pfizer-BioNTech's mRNA vaccines. This is an example of a dichotomous depiction as it presents the benefits (protection against severe COVID-19 outcomes) in contrast to the risks (myocarditis).
    • An increased risk was identified for developing Guillain-Barre syndrome among people who received AstraZeneca's jab. This is an example of inflammatory rhetoric as it describes the potential harm caused by COVID-19 vaccines in a dramatic and alarming way.
    • The experts at GVDV examined 13 medical conditions that they considered 'adverse events of special interest'. This is an example of an appeal to authority as it presents the opinions of experts without providing any evidence or context for their beliefs.
  • Bias (85%)
    The article reports on a study that found an increased risk of neurological, blood and heart-related medical conditions after receiving COVID vaccines from companies like Pfizer, Moderna and AstraZeneca. The author uses language that dehumanizes the vaccine recipients by referring to them as 'immunized' instead of people who have received a shot. Additionally, the article mentions rare occurrences of heart, brain and blood disorders which could be seen as sensationalizing or exaggerating the risks associated with vaccines.

          • COVID was the leading cause of death amongst children from a disease caused by an infection in 2021
          • A new study published this month found possible links between the COVID-19 vaccine and health conditions, specifically neurological, blood and heart-related conditions.
          • Dr. Michelle Fiscus, Chief Medical Officer leading a CDC-funded project to improve COVID-19 vaccination rates in children said that it is critically important for children to get vaccinated against COVID as they were the leading cause of death from an infection caused by disease in 2021.
          • This latest study may fuel the debate of risks and benefits of vaccines.
        • Accuracy
          • Possible safety signals for transverse myelitis were identified after viral-vector vaccines.
        • Deception (30%)
          The article is deceptive in several ways. Firstly, the author claims that COVID was the leading cause of death amongst children from a disease caused by an infection. However, this statement is false as per data from CDC and WHO which states that COVID-19 has not been reported to result in any deaths among infants or young children under 2 years old.
          • It's important to understand that last year COVID was the leading cause of death amongst children from a disease caused by an infection.
        • Fallacies (75%)
          The article contains an appeal to authority fallacy when Dr. Michelle Fiscus states that COVID vaccines are the most tested of any medications for children and have been highly tested among all vaccines ever had. This statement is not supported by evidence presented in the article.
          • ]It's important to understand that last year COVID was the leading cause of death amongst children from a disease caused by an infection."
          • But some experts stress getting COVID far outweighs the risks of getting vaccinated.
        • Bias (75%)
          The author uses language that dehumanizes children by saying 'last year COVID was the leading cause of death amongst children from a disease caused by an infection.' This is not accurate as COVID-19 does not directly kill children. The article also quotes Dr. Michelle Fiscus stating that these vaccines are highly tested and safe for children, which contradicts her earlier statement about the risks associated with them.

              • Fallacies (75%)
                The article contains several fallacies. Firstly, the author uses a false dilemma by stating that vaccines protect against severe illness and death or lingering long Covid symptoms from a coronavirus infection. This is not true as there are other ways to prevent these conditions such as wearing masks and practicing social distancing. Secondly, the article contains an appeal to authority fallacy when it states that rare events identified early in the pandemic were found in this study without providing any evidence of their validity or reliability. Thirdly, the author uses inflammatory rhetoric by stating that there is a higher risk of heart-related inflammation from mRNA shots made by Pfizer Inc., BioNTech SE, and Moderna Inc. This statement is not supported by scientific evidence and may be misleading to readers.
