Medicines and Healthcare products Regulatory Agency | March 2022 | Evusheld approved to prevent COVID-19 in people whose immune response is poor
In a clinical trial in adults, Evusheld was found to reduce the risk of developing symptomatic COVID-19 by 77 per cent, with protection from the virus continuing for at least 6 months following a single dose.
Developed by AstraZeneca, Evusheld is a combination of two long-acting antibodies that works by binding to the spike protein on the outside of the SARS-CoV-2 virus, the virus that causes COVID-19. This in turn prevents the virus from attaching to and entering human cells.
Evusheld is authorised to be used before being exposed to the risk of COVID-19 infection in order to prevent disease (known as ‘pre-exposure prophylaxis’).
There is not yet enough data to know how effective Evusheld is against Omicron or the duration of its effect against this variant, and the MHRA will work with the company to establish this.
In a clinical trial in adults, Evusheld was found to reduce the risk of developing symptomatic COVID-19 by 77 per cent, with protection from the virus continuing for at least 6 months following a single dose.
A single dose of the two medicines, tixagevimab and cilgavimab, should be given as two injections into a muscle by a healthcare professional.
