A highlight of minutes of the EMA's Pharmacovigilance Risk Assessment Committee (PRAC) concluding 9 April 2021, indicating they also were investigating four cases of unusual blood clots with low blood platelets, including one death, amongst people who had taken the Janssen COVID‑19 vaccine. The Janssen vaccine is approved but not yet deployed ...

European investigators have put forward one theory that the vaccine triggers an unusual antibody in some rare cases; others are trying to understand whether the cases are linked with birth control ...
Getting sick with COVID-19 carries an eight to tenfold higher risk of developing blood clots in the brain than the AstraZeneca vaccine – and by extension, most likely, the Johnson & Johnson ...

[222] According to the EMA these very rare adverse events occur in around 1 out of 100,000 vaccinated people.
The betacoronaviruses of the greatest clinical importance concerning humans are OC43 and HKU1 (which can cause the common cold) of lineage A, SARS-CoV-1 and SARS-CoV-2 (the causes of SARS and COVID-19 respectively) of lineage B, [2] and MERS-CoV (the cause of MERS) of lineage C. MERS-CoV is the first betacoronavirus belonging to lineage C that ...
AstraZeneca and Johnson & Johnson's vaccines can cause "mutant" proteins to escape cells, triggering a response in blood vessels, ... triggering a response in blood vessels, the scientists say. ...
