Just like an authentic expression of democracy in the implementation of human rights, the institutional framework of Cuban culture extends to the most remote parts of the country, as happens in the rice fields of the Ciego de Ávila's municipality of Chambas.

Few know that the girl Adriana Broche Alemán, from Ciego de Ávila, is the main soloist of Soberana, a song with which Coro Diminuto pays tribute to the creators of the Cuban vaccinal candidates who continue with their clinical trials for their final validation.

Adriana Broche Alemán is the daughter of one of the leading producers of the Agro-industrial Company Máximo Gómez, dedicated to processing of grains in the municipality of Chambas, and at the same time she is a guest soloist of the prestigious children's choir Diminuto.

The Cuban vaccine against Covid-19 as well as the opportunity for Adriana Broche Alemán to participate in acclaimed cultural projects in the country are strong examples of how the most elementary human rights are guaranteed on the island.
