Detailed Answer:
HI DEAR
WELCOME TO THE HCM,
Hepatitis A Vaccine is not known to cause such effects.
But any thing mild can happen to any human being with any vaccine.
It may be coincidental that he might be developing some viral infection causing such irritability and crankiness.
This can be overcome by giving some antipyretic like paracetamol in 4 hourly doses. Hope the Symptoms should be relive in day or two
Please check the site of injection if some swelling or redness is there kindly review it with your pediatrician.
Hope the query is answered.
Please feel free for further clarification.
Thanks
