The European Medicines Agency (EMA) confirmed the association on Friday, August 6, after the regulator’s drug safety committee, PRAC, assessed the available evidence from scientific literature. Medically known as immune thrombocytopenia, it occurs when the immune system mistakenly attacks and destroys platelets – cells that contribute to blood clotting. The Mayo Clinic continued to explain that the condition can lead to easy or excessive bruising.
Another symptom of the condition – if symptoms begin to appear – include “superficial bleeding into the skin”.
A rash will appear as “pin-point sized reddish-purple spots”, known as petechiae, on the lower legs.
The gums may also bleed, or nosebleeds may become more regular; it’s also possible that there may be blood in the urine or stools.
Another symptom can be an “unusually heavy menstrual flow” that is abnormal for the person experiencing it.

Moreover, the chance of developing immune thrombocytopenia seems to correspond with those who have other immune-related issues.
Examples of immune-related health issues include rheumatoid arthritis and lupus.
One rare complication of the condition is when there is a bleed on the brain, which can be fatal.
PRAC recommended updating the J&J vaccine information to include immune thrombocytopenia as a possible side effect.
“You may hear these sounds in one or both ears, or in your head,” added the NHS. “They may come and go, or you might hear them all the time.”
Separately, PRAC has requested further data from AstraZeneca to investigate its link to cases of Guillain-Barré syndrome.
Guillain-Barré syndrome is a “very rare” condition that affects the nerves.
It can lead to numbness, weakness, pain, and issues with co-ordination.
