Meningitis Vaccine Project

Last updated

The Meningitis Vaccine Project is an effort to eliminate the meningitis epidemic in Sub-Saharan Africa by developing a new meningococcal vaccine. The meningitis problem in that area is caused by a strain of meningitis called "meningitis A", which is present only in the African meningitis belt. In June 2010 various sources announced that they had developed MenAfriVac, which is an inexpensive, safe, and highly effective vaccine which is likely to stop the epidemic as quickly as anyone had ever hoped that it would.

Contents

The project marked the first time that medical research had developed a vaccine to combat a disease which is endemic to and only a problem for Africa.

The project began in 2001 when the Bill & Melinda Gates Foundation awarded the World Health Organization and the Program for Appropriate Technology in Health (PATH) a US $70 million seed grant to begin research.

In 2001, the Bill & Melinda Gates Foundation awarded the World Health Organization and the Program for Appropriate Technology in Health (PATH) a US$70 million seed grant to launch the Meningitis Vaccine Project. [1]

Implementation

The mission of the Project is to eliminate meningitis as a public health problem in sub-Saharan Africa through the development, testing, introduction, and widespread use of conjugate meningococcal vaccines. [2] The Project recently developed MenAfriVac, a low-cost conjugate A vaccine that is ready for widespread distribution to people between the ages of 1 and 29 in Burkina Faso, Mali, and Niger, [3] three countries in the African meningitis belt with the highest rates of meningitis. [4]

Manufacture

By working with the Serum Institute of India Ltd. to manufacture the vaccine, the Project was able to develop a vaccine that would be affordable to developing African countries, priced at less than $US.50 per dose. [5] Unlike existing vaccines, MenAfriVac also provides immunity for a long period of time—10 to 15 years—and is safe for use in infants one year of age and older. [3] Following successful trials, the vaccine was introduced in three African countries in 2010. [6]

<i>Neisseria meningitidis</i> Species of bacterium that can cause meningitis

Neisseria meningitidis, often referred to as meningococcus, is a Gram-negative bacterium that can cause meningitis and other forms of meningococcal disease such as meningococcemia, a life-threatening sepsis. The bacterium is referred to as a coccus because it is round, and more specifically a diplococcus because of its tendency to form pairs.

Meningococcal disease Medical condition

Meningococcal disease describes infections caused by the bacterium Neisseria meningitidis. It has a high mortality rate if untreated but is vaccine-preventable. While best known as a cause of meningitis, it can also result in sepsis, which is an even more damaging and dangerous condition. Meningitis and meningococcemia are major causes of illness, death, and disability in both developed and under-developed countries.

The Haemophilus influenzae type B vaccine, also known as Hib vaccine, is a vaccine used to prevent Haemophilus influenzae type b (Hib) infection. In countries that include it as a routine vaccine, rates of severe Hib infections have decreased more than 90%. It has therefore resulted in a decrease in the rate of meningitis, pneumonia, and epiglottitis.

Meningitis Inflammation of the membranes around the brain and spinal cord

Meningitis is an acute inflammation of the protective membranes covering the brain and spinal cord, known collectively as the meninges. The most common symptoms are fever, headache, and neck stiffness. Other symptoms include confusion or altered consciousness, vomiting, and an inability to tolerate light or loud noises. Young children often exhibit only nonspecific symptoms, such as irritability, drowsiness, or poor feeding. If a rash is present, it may indicate a particular cause of meningitis; for instance, meningitis caused by meningococcal bacteria may be accompanied by a characteristic rash.

Meningococcal vaccine Vaccines used to prevent infection by Neisseria meningitidis

Meningococcal vaccine refers to any vaccine used to prevent infection by Neisseria meningitidis. Different versions are effective against some or all of the following types of meningococcus: A, B, C, W-135, and Y. The vaccines are between 85 and 100% effective for at least two years. They result in a decrease in meningitis and sepsis among populations where they are widely used. They are given either by injection into a muscle or just under the skin.
