PROTECT AGAINST PNEUMOCOCCAL PNEUMONIA
Vaccination can help protect against pneumococcal disease.1
The Centre for Health Protection recommends the use of pneumococcal vaccines in persons aged 65 years and above and those with high-risk conditions.*2
*High-risk conditions include2: History of invasive pneumococcal disease, immunocompromised states (eg, asplenia, HIV infection, cancer or organ transplant recipient), chronic disease (eg, chronic heart disease, chronic lung disease, kidney or liver disease, diabetes), with cochlear implants, amongst others
Benefits of pneumococcal vaccines
You can’t get pneumococcal pneumonia from getting vaccinated because pneumococcal vaccines do not contain live bacteria.3
Vaccination can help protect you from pneumococcal disease.1
You do not have to get vaccinated every year.2,3
True or False?
You can’t get pneumococcal pneumonia by getting vaccinated.
True
False
True
That’s right.
You can’t get pneumococcal pneumonia from a vaccine because pneumococcal vaccines do not contain live bacteria.3
False
The truth is you can’t get pneumococcal pneumonia from getting vaccinated
because pneumococcal vaccines do not contain live bacteria.3
There are different types of pneumococcal vaccines in the market,
including polysaccharide (eg, 23-valent pneumococcal polysaccharide vaccine) and conjugate (eg, 13-valent pneumococcal conjugate vaccine, 20-valent pneumococcal conjugate vaccine) vaccines.4 These vaccines can help boost the immunity of your body to pneumococcal pneumonia. 5,6 When Streptococcus pneumoniae invades, your body can produce an immune response to defend it due to previous pneumococcal vaccination, protecting you against pneumococcal diseases.5,6
However, because polysaccharide vaccines are composed of free polysaccharides, they can only produce a short-term immune response and do not induce long-term immunity.5,7-9 On the other hand, conjugate vaccines are polysaccharides conjugated to a carrier protein, hence they can stimulate the immune system to produce antibodies and induce long-term immunological memory.5,7–9 Therefore, conjugate vaccines may provide longer-lasting protection than polysaccharide vaccines.5,7
