Thank you for reaching us, the validity of the prescription is specific for the concern raised during the consultation - There is an usual free follow up consult within 2 days post the consultation (depends on some doctors).
If it’s for a vaccination- then you would need a valid prescription given by a doctor mentioning the date of inoculation and it should be a recent one.
Do let us know for any more queries.
Best Regards,
