if the "source" website doesn't include the actual information, it's probably making shit up.
Pelo menos 9.878 brasileiros que morreram por covid-19 no Brasil já haviam tomado as duas doses da vacina ou a aplicação única do imunizante da Janssen, revela pesquisa da Info Tracker, plataforma de monitoramento da pandemia das universidades estaduai

the actual source for the information says that 10k died after full dosing and 20k died after 1 shot. There' no information on the condition or overall health of the people who got one shot. They also don't break out the distribution of vaccine types, but they do mention that 90% of the people who died after full-dose were over the age of 70....regardless, that 10k who died after full dosing (correlation not being causation) would represent 3.7% of the COVID deaths during the same time period.
when people post stuff like this, it's because they're trying to convince themselves that they have this all figured out.
they don't. no one does.
