how effective are the pneumonia vaccines?

The PPV vaccine is thought to be around 50 to 70% effective at preventing pneumococcal disease. Both the PPV and the PCV are inactivated or "killed" vaccines and do not contain any live organisms. They cannot cause the disease they protect against.

Get Vaccinated The flu is a common cause of pneumonia, so preventing the flu is a good way to prevent pneumonia. Children younger than 5 and adults 65 and older should get vaccinated against pneumococcal pneumonia, a common form of bacterial pneumonia.

Currently, Pneumovax 23, the inactivated pneumococcal polysaccharide vaccine (PPV), is indicated for all persons aged 65 and older. PPV is a 23-valent vaccine that protects against 23 of the more than 80 serotypes of pneumococcal bacteria.

People who need a pneumonia vaccine should get both shots: first, the PCV13 shot and then the PPSV23 shot a year or more later. For most people, one of each shot should be enough to protect them for their entire lives. Sometimes, you may need a booster shot.

Like with any vaccine, the vaccines that protect against these bacteria are not 100% effective. The vaccines also do not protect against all the types (strains) of each bacteria. For these reasons, there is still a chance vaccinated people can develop bacterial meningitis.

However, most people recover from pneumonia in about a week. Bacterial pneumonia usually starts to improve shortly after starting antibiotics, while viral pneumonia usually starts to improve after about three days. If you have a weakened immune system or a severe case of pneumonia, the recovery period might be longer.

Infected people are most contagious up to about 2 weeks after the cough begins. Antibiotics may shorten the amount of time someone is contagious. While pertussis vaccines are the most effective tool to prevent this disease, no vaccine is 100% effective.

One dose of MMR vaccine is 93% effective against measles, 78% effective against mumps, and 97% effective against rubella. Two doses of MMR vaccine are 97% effective against measles and 88% effective against mumps. MMR is an attenuated (weakened) live virus vaccine.

21 CDC Morbidity and Mortality Weekly Report, the current influenza vaccine has been 45% effective overall against 2019-2020 seasonal influenza A and B viruses.

Overall, the vaccine is 60% to 70% effective in preventing invasive disease caused by serotypes in the vaccine. PPSV23 shows reduced effectiveness among immunocompromised persons; however, CDC recommends PPSV23 for these groups because of their increased risk of invasive pneumococcal disease (IPD).
