Brazil is an example of a country that has already suffered from epidemics of dengue, chikungunya and zika. In this sense, the search for effective vaccines is a complex challenge due to the unique aspects of these viruses and the technical and scientific difficulties.
In the case of dengue, for example, there are four different serotypes of the virus. This means that a person can be infected and develop immunity to a specific serotype, but remain susceptible to others.

This complicates the creation of a vaccine effective against all serotypes at the same time. In some situations, immunization against only one can increase the risk of complications when the person is infected with another serotype.
This is because the immune system reacts in an aggravated way when encountering a different serotype after immunization.
Viruses have also evolved to enter the human immune system in complex ways. Consequently, this makes it difficult to develop an efficient immune response with vaccination.
This immune response needs to be directed not only to stimulate antibody production, but also to create successful cellular immunity.

bill Gates believe that a Biological weapon would be the ideal solution to contain dengue, zika and chikungunya. In addition to being known for being the founder of Microsoft, he is also recognized for being part of numerous initiatives.
Among them, the Project World Mosquito Program (WMP), a non-profit organization that is envisioning the production of mosquitoes to be used as biological weapons.
The World Mosquito Program is working on developing and implementing an approach known as the “Wolbachia Mosquito Technique”. Wolbachia is a natural bacteria present in many insects, including mosquitoes.
This technique involves releasing Wolbachia-infected male mosquitoes into the environment. When they fertilize wild females without Wolbachia, the resulting eggs do not develop properly and do not generate adult mosquitoes capable of transmitting disease.
This helps to decrease the population of vector mosquitoes and in turn reduces the spread of the diseases they carry.
The World Mosquito Program approach is an innovative and environmentally sustainable way of mosquito control. vectors, which focuses on minimizing the transmission of these diseases rather than eliminating them completely.
