What you're experiencing right now is not the side effects of the vaccine but it's actual function. You body is responding to the vaccine. This means the vaccine is working. As for the pain on your hand, it's because you probably held your hand stiff when you took the injection; deltoid muscle if held stiff can cause you the pain, this usually goes away in a span of 3 days but be sure to get it checked out if it persists. Pain in general and fever on the other hand is just your immune response. You have nothing to worry about. Side effects of the vaccine (if any) would probably take years to reveal itself although not necessarily.
