The pneumonia shot should be given to the patient once every 5 years, according to WebMD. The risk of pneumonia is higher for those who smoke or have pre-existing lung conditions.
There are two vaccines that prevent pneumonia. The first is a booster shot that should be given every 5 years. The second one is needed every year. People who have a lowered immune system, a lung condition, history of smoking or are elderly need this vaccine to prevent any major pneumonia virus. There may be slight side effects such as swelling, redness, muscle aches or fever, notes WebMD. If more severe side effects such as changes in behavior occur, the patient should be seen by a doctor immediately.
