Reports of this serious neurological illness was also at the
heart of trial halts in the early stages of development for both
AstraZeneca and J&J's shots, which are based on similar
technology.
Giving updates on the safety of all coronavirus shots, the
European Medicines Agency (EMA) said it was assessing reports of
a rare blood condition known as capillary leak syndrome (CLS)
following inoculation with Moderna's vaccine.
The EMA said it had recorded six cases of CLS and was assessing
all data, but it was not yet clear if there was a causal
association between the reports and the vaccine.
In CLS, fluids leak from the smallest blood vessels causing
swelling and a drop in blood pressure. The condition has also
been studied with vaccines from AstraZeneca and J&J.
The EMA said there was currently not enough evidence of a
possible link between rare cases of multisystem inflammatory
syndrome (MIS) and mRNA-based vaccines from Moderna and Pfizer-BioNTech
vaccine.
The regulator is reviewing if approved coronavirus vaccines
could cause MIS. The syndrome is a serious but rare condition in
which different body parts become inflamed, including the heart,
lungs, kidneys, brain, skin, eyes, or gastrointestinal organs.
J&J and Moderna did not immediately respond to requests for
comments.
