<p>It is known and proven that in order to prevent meningitis, maintaining and following the recommended vaccines is one of the best preventive measures against meningococcal disease. The author informs that the introduction of vaccination in the country has not significantly reduced recurrent cases of meningitis. According to the background presented, since the main problem is known, the best way to provide useful information to the public health system, to facilitate decision-making leading to a reduction in meningitis mortality, would have been to identify why vaccination does not affect the occurrence of new cases. Otherwise, the author should have simply described the epidemic profile of meningitis for the specified period in Burkina Faso.</p><p>The overall design of the study was appropriate, but not enough to guide the reader, the source of the data was not adequately named, he only said that it was secondary data... We do not identify how this past data informs his current research. In the result, he mentions that the under 5s are the most represented, 52.56. It is not clear what this number represents.</p><p>The conclusion is based on the results, but does not bring anything new in terms of information to the system. If it is possible that the author could make improvements, his work could be recommended for a poster.&nbsp;</p>
