I've been cold/flu like symptoms and i've heard about meningitis recently but i had a vaccine a little over 5 years. my neck is a little stiff and my bodys weak but i also are very little today and drank very little. any possibility it's meningitis?

Unlikely, however,: meningitis is the name for the disease which has several causative agents, bacterial or viral, the vaccine you received is against germs causing bacterial meningitis, not a routine vaccine, a booster may be needed in certain cases: e.g , known epidemic or traveling to an endemic area. Many people get viral meningitis and don't even know they had the disease, it resolves on its own, check w ur MD

Seriously doubt it: Your ability to submit a well worded question to this site makes that possibility quite remote. Meningitis is quite an overwhelming process. All the symptoms you mention are consistent with a cold/flu. If you are concerned go to urgent care.
