Thank you for your query at DoctorSpring.com
The three cardinal signs of meningitis are:
1) Neck catch or neck pain
2) Projectile Vomiting ( Distinguishing feature )
3) Headache with high-grade fever.
So, in absence of fever and vomiting, it does not sound like meningitis at all. Watch out for the development of symptoms as mentioned. Also, if vaccinated, chance of getting meningitis is low, but yes, possible in some cases.
Feel free to discuss further,
