TL;DR: In this paper , the authors present two cases of central retinal vein occlusion presenting immediately after receiving the second dose of the Covishield vaccine, although the causal relationship cannot be drawn, the ophthalmologist should be aware of this adverse reaction.
Abstract: Coronavirus disease 2019 (COVID-19) is known to cause thromboembolic episodes apart from acute respiratory distress syndrome (ARDS). With large vaccine drives all across the world, there are a few case reports on post-vaccine thrombotic events seen with the AZD1222, ChAdO × 1 vaccine. Here, we present two cases of central retinal vein occlusion presenting immediately after receiving the second dose of the Covishield vaccine. Although the causal relationship cannot be drawn, the ophthalmologist should be aware of this adverse reaction.

TL;DR: A case of ST elevation myocardial infarction reported post Coronavirus disease 2019 (COVID-19) vaccine was reported in this paper, however, it is premature to draw a link between COVID-2019 vaccine and myocardia.
Abstract: A case of ST elevation myocardial infarction reported post Coronavirus disease 2019 (COVID-19) vaccine. Probably premature to draw a link between COVID-19 vaccine and myocardial infarction.

TL;DR: In this article , a review of the reported adverse effects of COVID-19 vaccination was conducted and it was found that the incidence of all the reported cardiovascular events is very rare and the benefits of vaccination far outweigh the risk.

TL;DR: This point-of-view aims at providing a narrative review of epidemiological issues, clinical data, and pathogenetic hypotheses of thrombosis linked to both COVID-19 and its vaccines, helping medical practitioners to offer up-to-date and evidence-based counseling to their often-alarmed patients with acute or chronic cardiovascularThrombotic events.
Abstract: The coronavirus disease 2019 (COVID-19), a deadly pandemic that has affected millions of people worldwide, is associated with cardiovascular complications, including venous and arterial thromboembolic events. Viral spike proteins, in fact, may promote the release of prothrombotic and inflammatory mediators. Vaccines, coding for the spike protein, are the primary means for preventing COVID-19. However, some unexpected thrombotic events at unusual sites, most frequently located in the cerebral venous sinus but also splanchnic, with associated thrombocytopenia, have emerged in subjects who received adenovirus-based vaccines, especially in fertile women. This clinical entity was soon recognized as a new syndrome, named vaccine-induced immune thrombotic thrombocytopenia, probably caused by cross-reacting anti-platelet factor-4 antibodies activating platelets. For this reason, the regulatory agencies of various countries restricted the use of adenovirus-based vaccines to some age groups. The prevailing opinion of most experts, however, is that the risk of developing COVID-19, including thrombotic complications, clearly outweighs this potential risk. This point-of-view aims at providing a narrative review of epidemiological issues, clinical data, and pathogenetic hypotheses of thrombosis linked to both COVID-19 and its vaccines, helping medical practitioners to offer up-to-date and evidence-based counseling to their often-alarmed patients with acute or chronic cardiovascular thrombotic events.
