In the outbreak of a variant first detected in Colombia, seven residents of a Belgian retirement home have died despite having completed vaccination. This is announced by virologist Marc Van Ranst of the University of Leuven. The seven people were all 80 years old or older and in poor general health, he said. In total, 21 residents and several employees were infected with variant B.1621 in the home in Zaventem. The latter had shown only mild symptoms. Van Ranst called the deaths among those fully vaccinated worrisome. The variant currently accounts for two percent of cases in the United States, but has rarely been detected in Europe.

So - currently - 33% lethality if you're fully jabbed and 80+ ... not good.
