One of most glaring LIES pushed by MSM during "covid" was that natural immunity was insufficient or unable to be relied upon for this " virus." Herd immunity was disrupted due to isolation and oversanitizing recommendations. I have personally experienced the wonder of our immune responses. As an RN working in the emergency care setting, it was quite obvious. New staff would get ill for the first 3-6 months due to exposure to all types of "germs." After that time frame the statistics of sick call offs showed a dramatic decline.
The CDC recommendations for "covid" were designed to weaken the immune system. This was the first HUGE red flag to me. 😇
