check engine light flashes 5 times when key is in the ignition on position 2. on 2008 Honda Accord

It flashes 5 times and then disappears for good. This started happening after I had my car jump started due to drained battery. Should I be concerned and how can I get it NOT to before???

Are you sure it is the Check Engine light? It should come on with the ignition turned on, go out when the engine starts, come on and stay on if the computer sees a fault (and stay on if the fault remains present). If the light constantly flashes there is a serious emission fault, but it would stay flashing. Look in your owner's manual.
