Hvis du, forud for vaccinationen med Fendrix, allerede er smittet med hepatitis B- virus, men endnu ikke mærker noget ubehag, kan Fendrix ikke nødvendigvis forhindre, at du bliver syg.
Also, if you have already been infected with hepatitis B virus prior to receiving Fendrix, but you are not yet feeling unwell, Fendrix may not be able to prevent you from becoming ill.
