More than 300 Brazilians gathered on São Paulo's main commercial thoroughfare on Sunday to protest state Governor João Doria's support for mandatory COVID-19 immunization and testing the potential vaccine developed by China's Sinovac . Doria has previously spoken in favor of making immunizations mandatory, once vaccines are available, sparking a spat with President Jair Bolsonaro who vows it will be voluntary. The Supreme Court's chief justice has said the court will ultimately decide on the issue.
