A case of ischemic stroke and transient thrombocytopenia in a young female following adenoviral vector-based COVID-19 vaccination: Was the association incidental or causal?
We report a 23-year-old healthy female who developed seizures, altered sensorium, and left hemiparesis, 20 days after receiving the first dose of adenoviral vector-based COVID-19 vaccine "Covishield™." The patient had transient thrombocytopenia. The D-dimer level was 2460 ng/mL. Magnetic resonance imaging (MRI) demonstrated occlusion of M2 segment of the middle cerebral artery and cerebral infarction. Platelet factor-4 antibodies level was normal. Treatment with aspirin and antiepileptic drugs resulted in a remarkable recovery. This is the first Indian case report of ischemic stroke and transient thrombocytopenia followi...

Vaccination, Acute Myocardial Infarction, and Ischemic Stroke After COVID-19 Infection —Reply
In Reply We thank Dr Chu and colleagues for their comments about our Research Letter. Our analysis found that 2 doses of COVID-19 vaccine were associated with a reduced risk of AMI and ischemic stroke after COVID-19, using inverse probability treatment weighting to mitigate the imbalance in patient characteristics by vaccination status.

Cerebrovascular Complications of COVID-19 and COVID-19 Vaccination
Circ Res. 2022 Apr 15;130(8):1187-1203. doi: 10.1161/CIRCRESAHA.122.319954. Epub 2022 Apr 14.ABSTRACTThe risk of stroke and cerebrovascular disease complicating infection with SARS-CoV-2 has been extensively reported since the onset of the pandemic. The striking efforts of many scientists in cooperation with regulators and governments worldwide have rapidly brought the development of a large landscape of vaccines against SARS-CoV-2. The novel DNA and mRNA vaccines have offered great flexibility in terms of antigen production and led to an unprecedented rapidity in effective and safe vaccine production. However, as mass vac...

Changes in incidence rates of outcomes of interest in vaccine safety studies during the COVID-19 pandemic
CONCLUSION: Rates of some clinical outcomes during the pandemic changed and should not be used as historical background rates in vaccine safety studies. Inclusion of telehealth visits should be considered for vaccine studies involving Bell's palsy, ITP, and narcolepsy/cataplexy.PMID:35465977 | DOI:10.1016/j.vaccine.2022.04.037

Risk of serious adverse events after the BNT162b2, CoronaVac, and ChAdOx1 vaccines in Malaysia: A self-controlled case series study
CONCLUSION: This study shows acceptable safety profiles of COVID-19 vaccines among recipients of BNT162b2, CoronaVac, and ChAdOx1 vaccines. This information can be used together with effectiveness data for risk-benefit analysis of the vaccination program. Further surveillance with more data is required to assess AESIs following COVID-19 vaccination in short- and long-term.PMID:35667917 | DOI:10.1016/j.vaccine.2022.05.075
