Natural Immunity vs Vaccine Immunity

The vaccines only produce an immune response against 2 antigens the spike protein and the receptor binding domain and declines within 4-6 month after vaccination and so booster are required.
Natural infection however, produces an immune response, antibodies, and memory B cells and CD4-T cells against 20 different epitomes, 20 different antigens, 20 different proteins that the immune system recognise as foreign and is likely to maintain the for years.
