You have won August congratulations and therefore get the bonus for winning. You only need 3 objectives and only the cure 3 diseases is mandatory.The immunologist search will remain around until you complete it, or unless a card in the legacy deck says you don't need to search for it anymore.
Remember you can help stack the chance for completing the search in your favour to complete it if you take time to prepare (use the right characters, use rivals/soldier +equipment/flexible to reuse city cards. we also found the dispatcher amazing as they let you use your last actions to play cards and then The dispatcher can rescue characters in trouble).
