How Long Do Symptoms Last?A person with bacterial pneumonia usually starts to feel better three to five days after the medicines are started. He or she can usually return to normal activities within a week. Tiredness and a mild cough can take longer to improve -- in some cases, taking upwards of a month or longer to get better.
People who are treated in the hospital may need at least three weeks before they can go back to their normal routines.
Vaccines Used to Prevent Bacterial PneumoniaSeveral vaccines are available to prevent certain types of bacterial pneumonia. These vaccines can't prevent all cases, but they definitely help.
Pneumococcal pneumonia is the most common form of pneumonia, and the pneumococcal vaccine is one of the most effective ways of preventing it. Many different vaccines are used to prevent pneumococcal diseases in children and adults. They include the pneumococcal conjugate vaccine (Prevnar®, Prevnar 13™) and the pneumococcal polysaccharide vaccine (Pneumovax®).
Haemophilus influenzae type b (Hib) disease is a serious illness caused by bacteria. Before the Hib vaccine, this disease was the leading cause of bacterial meningitis among children younger than five years old in the United States. Meningitis is an infection of the brain and spinal cord coverings, which can lead to lasting brain damage and deafness. Hib disease can also cause pneumonia, among other serious conditions.
The Hib vaccine is recommended for all children in the United States who are younger than five years old. It's often given to infants, starting at two months of age.
