Vaccine-induced immune thrombocytopenia and thrombosis (VITT) is a combination of blood clots and low platelet levels that are associated with the viral vector covid vaccines made by AstraZeneca and Johnson & Johnson. Thrombocytopenia is a condition where an individual has low platelet count. Thrombosis is caused when the blood clots block veins or arteries, resulting stroke, heart attack and other such ailments.
UK scientists have identified markers associated with these side effects and have issued guidelines to doctors to help them effectively diagnose and increase the chance of survival. Age restrictions were imposed on AstraZeneca’s shot as side effects were mostly seen in younger people.
