I hope this will be helpful to some who are worried by this story:
theconversation.com/blood-clot-risks-comparing-the-astrazeneca-vaccine-and-the-contraceptive-pill-158652
The likelihood of a clot from the vaccine is given here as 1 in 250,000. Whereas the likelihood of getting a clot from the contraceptive pill is about 1 in 1000. The article acknowledges that the types of clots are different and the post-vaccine clots could be more serious. But, as someone who had a blood clot caused by the pill that developed into a life-threatening pulmonary embolism, I know that clots from the pill can be very serious too.
The article goes on to point out that between 40-95% of people with significant illness from Covid will develop clots. So if you catch Covid and become quite unwell your risk of some sort of clotting is very high.
Whether or not to have any vaccine is your decision but it’s helpful to have a sense of the relative risks, I think.
Also Mumsnet has around 7 million unique user visits each month, so one would certainly expect that there will be users on here who know someone who has had a clot after the vaccine. That doesn’t make it any less scary and worrying for those affected but again it would be odd given a prevalence of 1 in 250,000 if there weren’t users on here who have sadly been affected by this.
