As the City of Manila is the host of the SDG event, and as this year marks 450th anniversary of founding of the city, it is only appropriate that the organizers gave full support to the UNESCO Programme Día del Galeón or Galeón de Manila celebrating circumnavigation of the world in 16th century.. Professor Jesus de Salvador of the Catholic University of Valencia has sent a message explaining the first global attempt at immunization along Galeón de Manila: in the Philippines, Spain, and today’s Mexico. This is particularly relevant in view of the current pandemic.
