2. As a rule, Naval Medical Officers should carry out vaccinations and re-vaccinations by the above method, making one insertion only, by means of a single linear scratch. If there are special reasons for desiring additional protection, more than one insertion may be made. In no circumstances should the vaccinated area by cross-scarified or cross-hatched. The "multiple pressure or prick" method may be used by medical officers who are familiar with its technique and interpretation.
3. Cases of primary vaccination are to be regarded as successful when a normal vaccine vesicle has been produced. Cases of re-vaccination are to be regarded as successful when either a vesicle or a papule surrounded by an æola has resulted. Re-vaccination of active service 36W personnel should be carried out every five years.
Extract from K.R. & A.I.
Re-vaccination of active service personnel should be carried out every five years, except for Officers and men appropriated to the East Indies or China Stations for whom the interval for re-vaccination is three years.
