Hi all, I’m due to get my booster shortly. I’ve already had two doses of Pfizer. I’m excited to be getting the extra protection. I’ve searched online for concrete/scientific information on efficiency of the booster. I can’t find anything. I’ve seen it posted on other threads that the booster doubles existing immunity, results in 95% immunity, etc. if anyone can point me to some trustworthy stats or information I’d be very grateful!
