EMA’s notifies about the uncommon blood clots and low
blood platelets after COVID-19 vaccine to avoid treatment delays and obstacles.
The Pharmacovigilance Risk Assessment
Committee (PRAC) of EMA issued a warning about unusual blood clots and low platelets due to a
COVID-19 Vaccine of a renowned pharmaceutical on 20 April 2021. As a cautionary
mesure, PRAC emphasized on adding these events on the product info as
uncommon side-effects of the vaccine.
This conclusion was based on considering existing evidence
including 8 reports of serious cases of unusual blood clots linked with
decreased levels of platelets (aged less than 60 years), one of which had a
serious outcome in 3 weeks following the vaccination. This vaccine has been
administered in >7 million people in
the US till 13th April, 2021.
This committee observed that the blood clots appeared
mainly at uncommon sites, for example in veins in the brain's venous sinuses (cerebral venous
sinus thrombosis, CVST) and abdomen (splanchnic vein thrombosis) and in
arteries, along with decreased platelets and occasionally bleeding.
Prior to receiving the vaccine, the healthcare providers and
individuals should be aware of risks of very rare cases of blood clots and
decreased platelets arising in 3 weeks of vaccination.
COVID-19 infection is linked with a peril of hospitalisation
and death. The reported combination of blood clots and low platelets is unexpected,
and the total advantages of this vaccine in COVID-19 prophylaxis compensates
the side effects.
One plausible clarification for occurrence of blood clots and
decreased platelets is an immune response, causing a disorder similar to
heparin induced thrombocytopenia.
Timely identification and treatment of signs of
bloods clots and low platelets can promote recovery and elude complications in
affected patients.
EMA will endure to screen the vaccine’s safety
and efficacy and offer up-to-date information concerning all the vaccines.
