Baby won’t sleep after injections

Since my 8 week old had his injections a few days ago he is not sleeping! Takes hours of him crying for me to get him to sleep and when he does he only sleeps for 20-30 minutes before waking up screaming again every day and night. 😩

Was anyone else’s baby like this after their shots? He never used to be like this and i can’t do anything now as all my time is spent trying to stop him from screaming.
