That sounds scary. I'm vaccinated twice and I've decided that I won't mix vaccines for the booster. I'm staying with what I know isn't hurting me. Yet I'm tracking a lot of my sporting data (I do at least 1h of bike riding a day) and noticed that I'm not as energetic as half a year ago. But this may also be because of an accident I had where I hurt my shoulder pretty bad and I'm also not eating as much in order to loose some weight. I've been thinking about analyzing all that data to find out when this "decay" started.
