Any side effect for getting a flu shot and a pneumonia vaccine every year?

Immunizations: Annual flu shot good idea: may feel achy few days while body builds defenses against flu viruses. Pneumonia vaccine generally not given every year unless immune system is compromised. Originally was given one time; now may be given more than once in elderly who don't mount as strong an immune response. Both can cause localized soreness at injection site. Rare possibility of guillain-barré syndrome.
