Children are dying from Streptococcus pneumonia especially in developing countries

The WHO estimates that globally Streptococcus pneumonia kills close to 500,000 children under 5 years annually. That’s a HUGE number. And that’s just children UNDER FIVE.

S. pneumonia can cause diseases such as pneumonia. meningitis, and bacteremia. (Refer to graphic below.) These are diseases that put babies and children in the hospital.
I’ve been hospitalized twice for pneumonia and I can’t imagine having to watch my child or any child go through such pain and suffering.

We do have a vaccine to help protect from this disease. The pneumococcal conjugate vaccines (PCV)–there are two versions–have had clear public health benefits. Not only does it reduce the invasive disease in vaccinated children, but also in elderly adults who benefit from herd immunity.

Coverage is increasing globally, but it’s nowhere near optimal vaccination rates.

Most of these child deaths occur in developing countries where they do not yet have access to vaccines.

How are vaccines made and released to the public?


A vaccine’s main goal is to teach your immune system to recognize and remember a bacteria or virus.
The word “vaccination” means to stimulate the immune system to make antibodies¬†against the bacteria or virus targeted by the vaccine.
“Immunization” is different; it’s used in relation to injecting a person with pre-formed antibodies to a particular disease to make the person immune to it.
These terms are often used interchangeably, and that’s just fine, however it’s important to understand that these are two very different ways of creating immunity to a disease.
