When you schedule a multi-dose vaccine (e.g., Rabies HDVC), you record several dates over a number of days, weeks or months. During this period, the brand of vaccine you have available may change: certain vaccines are interchangeable with other brands and so can be swapped for the branded initially scheduled. The Substitute Vaccine feature provides this ability without requiring you to reschedule vaccines.
After creating a vaccine schedule and administrating the first dose in the schedule, the patient will return at the appropriate day for the next administration. For whatever reason, you wish to use an alternative but equivalent brand of vaccine.
The existing vaccine brand is substituted and you can administer the substitute vaccine and set the batch number, as with any other vaccine. On the Vaccine Cover page an asterisk appended to a vaccine indicates that a substitute has been used. The tooltip provides the details, as does the Patient Summary Report.
