The coronavirus disease 2019 (COVID-19) vaccine is the hope for the management of the COVID-19 outbreak. At present, the COVID-19 vaccine is already in use in several countries. An important concern is the adverse effect of vaccination. There are many possible adverse effects of the COVID-19 vaccine including vascular complication. The possible neurological complication due to the COVID-19 vaccine is an important present consideration. There are many recent reports on neurological incidences including stroke-like complication after vaccination.
In a recent local report from Indochina (https://www.reuters.com/world/asia-pacific/thailand-sticks-with-sinovac-vaccine-after-cases-stroke-like-side-effects-2021-04-21/), a post-COVID-19 vaccination stroke-like incidence occurs. A patient with underlying breast cancer is a member of all six affected cases, there is a patient with underlying breast cancer. It is questionable on the exact pathomechanism of the incidence. Indeed, a possible explanation of post-vaccination vascular complication is the change of blood viscosity. The COVID-19 vaccination can result in a change of blood viscosity due to an increased level of immune elements. An increase in immunoglobulin is confirmed as a possible cause of increased blood viscosity. A cancer patient, including the one with breast malignancy, might have a background high-blood viscosity. Therefore, after vaccination, a hyperviscosity might occur, and it might result in a stroke-like event. For COVID-19 vaccination, it should be used with precaution in a patient with the underlying malignancy.
