The thrombosis events associated with the COVID‑19 vaccine may occur 4–28 days after its administration and mainly affects women under 55.

Elevate arm and rest in elevated position. If there are blisters on the arm, aspirate content of blisters with a new thin needle. Warm compresses should be placed initially on the site to help diffuse the contrast medium, and cold compresses are used later to help reduce the swelling.
Mechanisms underlying the cause of reactogenicity symptoms. In clinical trials, reactogenicity is the capacity of a vaccine to produce common, "expected" adverse reactions, especially excessive immunological responses and associated signs and symptoms, including fever and sore arm at the injection site.
The updated COVID-19 vaccine is now available. Infectious disease doctors recommend being smart about the timing of your shot. You can expect similar side effects to the previous vaccines if you ...
The arm in which you get your Covid-19 booster may increase the amount of immune cells you produce. Researchers share what you need to know. Which arm gets the Covid-19 booster may make a ...
For instance, one study of about 300 people from 2023 found that getting both initial COVID-19 vaccines in the same arm produced the strongest immune response (but, importantly, alternating arms ...
Vaccine-induced seropositivity (VISP) is the phenomenon wherein a person who has received a vaccine against a disease would thereafter give a positive or reactive test result for having that disease when tested for it, despite not actually having the disease.
Arthus reactions (type III hypersensitivity reactions) are rarely reported after vaccination and can occur after tetanus toxoid–containing or diphtheria toxoid–containing vaccines. An Arthus reaction is a local vasculitis associated with deposition of immune complexes and activation of complement.
