How quickly does a booster vaccine wear off?ĮMA's vaccine side effects update: Moderna.While the EMA does not provide an estimation of the incidence rate of cutaneous small vessel vasculitis as a side effect of the Janssen vaccine, the agency categorises it as a “very rare” event. The body had previously recommended the inclusion of cutaneous small vessel vasculitis on Janssen’s product information in its September safety update, before suspending this conclusion after the pharmaceutical company asked for a re-assessment. The EMA describes cutaneous small vessel vasculitis as “inflammation of blood vessels in the skin which may result in a rash, pointed or flat, red spots under the skin’s surface and bruising”. In its latest monthly safety report, released on 17 March, the EMA’s Pharmacovigilance Risk Assessment Committee (PRAC) said it had recommended that cutaneous small vessel vasculitis be added to the Janssen vaccine’s product information as a potential side effect “of unknown frequency”. EMA's vaccine side effects update: Janssen 152m doses of the vaccine had been given in the EU/EEA as of 28 February, and just under 210m had been injected in the US as of 10 March. Meanwhile, the Moderna shot comprises two initial injections. In the US, 18.5 million doses had been administered as of 10 March, per the Centers for Disease Control and Prevention (CDC). As of 28 February, 19.2m doses of the drug had been given to people in the EU/EEA, the EMA says. The Janssen vaccine is initially administered as a single injection. Essentially, mRNA is a messenger that teaches the cells in our body how to create the proteins that spark an immune response to the virus. ![]() While Janssen uses a modified version of another virus to combat the coronavirus that leads to covid-19, the Moderna vaccine harnesses mRNA technology. In the United States, the Federal Drug Administration (FDA) has issued emergency or full approval to Janssen, Moderna and Pfizer. The Janssen and Moderna jabs are two of five vaccines approved for use in the European Union and European Economic Area (EU/EEA), alongside the Pfizer, AstraZeneca and Novavax vaccines. The European Medicines Agency (EMA) has updated its list of side effects associated with covid-19 vaccines, recommending amendments to the product information for the Janssen and Moderna shots. ![]()
