NATURE: Six months of COVID vaccines: what 1.7 billion doses have taught scientists. Note this:

Mehul Suthar, a viral immunologist at Emory University in Atlanta, Georgia, is concerned that vaccine-induced immunity will not be as durable as immunity from natural infection. Suthar says that he and his collaborators have found that antibody levels declined faster in those who were vaccinated with the Moderna vaccine than in those who had been infected by SARS-CoV-2. Antibodies are not the only determinant of immunity, he says, but the results worry him. “I’m a little concerned that the vaccines weren’t as robust in generating more durable antibody responses,” Suthar says. “When you factor in variants, to me it’s clear that we’re going to need a booster.”

Emphasis added. I think we’re seeing an emerging scientific consensus that natural immunity is stronger than vaccine-induced immunity. That’s not unusual, as Rand Paul has noted, but much of the vaccine-talk for a while seemed to suggest otherwise.
