Anyonw can speak from their personal experience and I can speak from someone else's personal experience too.

My mother is a doctor and she was sick with Covid- not once but twice. She just had her antibodies checked and they were just as high as someone who just had Covid.

Many studies have already proved that people who've had Covid have strong natural protection, thanks to T cell immunity. Whereas immunity from Covid-19 shots only offers short-term protection.

I'm afraid your response is grounded in fear and hysteria rather than reasonable thinking.
