So simple to answer your question. I am shocked you are asking that question.
Have 500,000 people died from common cold in one year?
If we’ve had the ability to solve the common cold, a solution worth trillions of dollars, why haven’t we?
If we have the ability to create a single permanent vaccine for the flu, worth trillions saving millions of lives, why haven’t we?
Do you believe every government reported number like every death a covid death and essentially NO flu deaths?
I’m skeptical of several bits of illogic here. Are you buying it hook line and sinker?
