COVID-19 vaccines are unlikely to protect those who are at a higher risk. A 2006 study: Vaccines fail to generate protective immunity in 50% to 90% of older individuals.

The brainwashed masses are ready to inject themselves with anything. But will vaccines work in those who are in the high-risk group, that is, people aged 70 and older? It is unlikely. According to a 2006 study by Corsini et al., the currently available influenza vaccines do not work in 70% of those aged 70 to 80 do develop antibodies after a flu vaccination. Among those aged 80 and above, 90% do not develop antibodies after a flu vaccine administration.

Seroconversion after a vaccine is 50% from 60 to 70 years old, 31% from 70 to 80 years old, and only 11% after the age of 80.
Conclusions: Billions are being spent on COVID-19 vaccines that are unlikely to work in the highest-risk group, those aged 70 and above.
