Vinìcius has been called into Brazil's senior squad for the first time ahead of next month's friendlies against Panama and Czech Republic.
The 18-year-old forward has become a key member of Real Madrid's first team under Santiago Solari since joining from Flamengo before the start of this season.
National team boss Tite has seen more than enough to be persuaded over the merits of adding the youngster to his forward line, while Vinicius' former Flamengo team-mate Lucas Paquetà has won a first call-up since joining AC Milan in the last transfer window.
The games against Panama in Porto on 23 March and versus Czech Republic in Prague three days later are the final opportunities Tite will have to see Brazil in action before his country hosts the 2019 Copa América.
