It's important to understand that the relationship between COVID-19 and blood clots is complex, and the risk varies depending on several factors, including:

• COVID-19 infection itself:
  • COVID-19 infection significantly increases the risk of blood clots. This risk is considerably higher than the risk associated with COVID-19 vaccines.
  • The severity of the COVID-19 infection also plays a role, with hospitalized patients having a higher risk.
• COVID-19 vaccines:
  • Certain COVID-19 vaccines, particularly the Johnson & Johnson/Janssen vaccine, were associated with a rare but serious type of blood clot called thrombosis with thrombocytopenia syndrome (TTS). This risk was observed to be higher in younger women.
  • mRNA vaccines (Pfizer-BioNTech and Moderna) have a much lower risk of blood clots.
• Individual risk factors:
  • Pre-existing conditions, such as a history of blood clots, certain genetic factors, and the use of hormonal birth control, can increase the risk.
  • Age is also a general risk factor for blood clots.

Here's what I can tell you from the information available:

• COVID-19 infection and blood clots:
  • Studies have shown that COVID-19 significantly elevates the risk of both arterial and venous blood clots. This risk persists for an extended period following infection.
  • Older individuals, and those with more severe covid infections, are at higher risk.
• Vaccine Associated risks:
  • Specifically relating to the J&J/Janssen vaccine, TTS was seen to occur at higher rates in females aged 30-49. This resulted in the recommendation that mRNA vaccines be used in place of the J&J vaccine.
  • mRNA vaccines carry a much smaller risk of blood clots.

Therefore, while there is a recognized increased risk of blood clotting associated with a covid 19 infection, especially in older individuals, the risk of vaccine induced clotting is far lower, and specific to certain vaccine types.

It's crucial to consult with a healthcare professional for personalized advice regarding COVID-19 and blood clot risks.
