This is interesting in our Covid vax psychotic world, with the establishment eschewing natural immunity to boost the profits of Big Pharma which now rules the world through medical biofascism. Research by Joelle Pelletier and Jean-François Masson, at Université de Montréal's Department of Chemistry, investigated whether natural infection or vaccination led to more protective antibodies being generated, and published their findings in the journal Scientific Reports. "Everyone who had been infected produced antibodies, but older people produced more than adults under 50 years of age," said Masson. "In addition, antibodies were still present in their bloodstream 16 weeks after their diagnosis." "But the result that surprised us the most was that antibodies produced by naturally infected individuals 50 and older provided a greater degree of protection than adults below 50, " said Pelletier."This was determined by measuring the antibodies' capacity to inhibit the interaction of the Delta variant's spike protein with the ACE-2 receptor in human cells, which is how we become infected," he added. "We didn't observe the same phenomenon with the other variants."
