Because immunity varies by disease.
Chicken pox? Pretty much one and done. COVID? Falls off rapidly after 3 months, whether you catch it or get the vaccine
Plus, every mutation is a dice roll on how much existing immunity will apply. It could be exactly the same as the last strain, or the old immunity might not help at all
