De hyppigst forekommende bivirkninger er et kompleks af influenzalignende symptomer (feber, kuldegysninger, ledsmerter, ubehag, perspiration, hovedpine eller muskelsmerter), som hovedsagelig skyldes lægemidlets farmakologiske effekt, samt reaktioner ved injektionsstedet.
The most frequently observed adverse reactions are a flu-like symptom complex (fever, chills, arthralgia, malaise, sweating, headache, or myalgia), which is mainly due to the pharmacological effects of the medicinal product, and injection site reactions.
