"Immunocompromised individuals who are eligible for a three-dose
primary series may receive a booster dose ≥6 months (168 days) after
completion of the primary series"

primary series and the third dose is at least two months (56 days). As per NACI,
the minimum interval is 28 days; however, an interval longer than the minimum
of 28 days between doses is likely to result in a better immune response."
