The hashtag #clotshot started trending on Twitter on July 14, 2021.
A clot shot is a vaccination that causes blood clots in the body of the vaccinee.
Due to press releases by national medical agencies like the CDC, post-vaccination blood clots are commonly associated with the Jannsen brand of COVID-19 vaccines, although cases with Pfizer and Moderna are also anecdotally widespread.
The very first use of the hashtag #clotshot appears to be from the @Beas23Linda account on April 8, 2021.
In France, the police have been exempted from mandatory vaccination.
