The invention relates to a peptide immune booster, comprising: a polypeptide (i) with an amino acid sequence having a length of 30 amino acids contained in the head domain of the fibre protein of the capsid of an adenovirus, said amino acid sequence comprising the sequence of amino acids forming a double ss sheet called EF , contained in said head domain, or a peptide analogue (ii) of said polypeptide (i), the amino acid sequence of which has, by comparison with the sequence of polypeptide (i), at least one substitution or at least one deletion of an amino acid, said analogue peptide conserving the double ss sheet called EF . |
