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 | PMC:PMC9163997 | DOI:10.1016/j.vaccine.2022.05.075

Hyperviscosity syndrome in COVID-19 and related vaccines: exploring of uncertainties
In conclusion, COVID-19 and related vaccines are linked with the development of HVS, mainly in patients with previous COVID-19 and underlying metabolic derangements. The possible mechanism of HVS in COVID-19 and related vaccines is increasing levels of fibrinogen and immunoglobulins. However, dehy dration, oxidative stress, and inflammatory reactions are regarded as additional contributing factors in the pathogenesis of HVS in COVID-19. However, this critical review cannot determine the final causal relationship between COVID-19 and related vaccines and the development of HVS. Prospective and retrospective studies are warranted in this field.

Isolated and Combined Unilateral Central Retinal Artery and Vein Occlusions After Vaccination. A Review of the Literature
Retinal artery occlusion (RAO), especially central RAO, is a sight-threatening and potentially blinding ophthalmic emergency. Recent publications reported its association with coronavirus disease 2019 (COVID-19) mRNA vaccines. Although rare, vaccines have been linked to ophthalmic complications, and it is of interest to examine the current literature on vaccine-related RAO.

Correspondence on “Patients with Acute Ischemic Stroke Previously Vaccinated Against COVID-19”
Dear Editor, we read and follow the publication on the “Clinical Characteristics of Patients with Acute Ischemic Stroke Previously Vaccinated Against COVID-19” saga.1 There are no significant variations in clinical characteristics of stroke in vaccinated versus unvaccinated patients, according to Stamenkovi et al. We found no evidence of a link betw een vaccination and stroke.1 Since the basic Wirchow's triad is the accepted explanation for the pathophysiological process of the stroke, we agree that there should be no difference in the pathogenesis of the stroke in cases with and without vaccination history.

Insights Into Immunothrombotic Mechanisms in Acute Stroke due to Vaccine-Induced Immune Thrombotic Thrombocytopenia
In conclusion, insufficient resolution of NETs, e.g. by endogenous DNases or protection of NETs against degradation by embedded factors like the antimicrobial peptide LL-37 might thus be an important factor in the pathology of VITT besides increased NET-formation. On the basis of these findings, we discuss the potential implications of the mechanisms of disturbed NETs-degradation for diagnostic and therapeutic approaches in VITT-related thrombogenesis, other auto-immune disorders and beyond.

The Hospitalization Rate of Cerebral Venous Sinus Thrombosis before and during COVID-19 Pandemic Era: A Single-Center Retrospective Cohort Study
CONCLUSION: Since there was a more dismal outcome in COVID-19 associated CVST, a high index of suspicion for CVST among COVID-19 positive is recommended.PMID:35523051 | PMC:PMC8947940 | DOI:10.1016/j.jstrokecerebrovasdis.2022.106468

Intracranial aneurysm rupture within three days after receiving mRNA anti-COVID-19 vaccination: Three case reports
CONCLUSION: Although the advantages of COVID-19 vaccination appear to outweigh the risks, pharmacovigilance must be maintained to monitor potentially fatal adverse events and identify possible associations.PMID:35509565 | PMC:PMC9062907 | DOI:10.25259/SNI_1144_2021
