All patients had recently recovered from mild #COVID19 and had fever, cough and chills.
Antibody levels rose with age: 60-85 yo had >3x the amount than 15-39 yo.
Other parts of the immune system, such as T-cells or cytokines, may have played a key role in fighting #coronavirus.

This study is PRELIMINARY and needs to be peer-reviewed. If confirmed, these results suggest that a standard vaccine approach (to generate neutralizing antibodies) *may* not be effective in a relatively large portion of the population.
