Meningitis shot

Hi all,

I got my meningitis shot for college yesterday and ever since that my blood sugar has been ridiculously high.  Is it the shot or am I just doing something wrong?  And if it is the shot, how long will these high readings last?

My son got his flu shot on Tuesday, then yesterday and today had numbers up in the 400s (crazy high for him).  It dawned on me last this afternoon that maybe it was the flu shot.
