They had to have a fallback position after their efficacy claims proved false, and they had to admit they never actually tested for spread.How do you know the vaccine worked? Well my friend's mom's sister only got a severe cough and a high grade fever, but she didn't have a cough or sore throat. So the vaccine must have saved her from dying.
This is the rationale of the vaccine makers use. They are basing effectiveness on how many symptoms a person has, even though every person has a different set of symptoms. It's a joke. Read the research and you will see.
Same goes for the influenza vaccine for what it's worth.
In fairness, there is a tiny window where the so-called vaccines and boosters worked for unhealthy people.
We tend to forget the death rate before vaccines was tiny for healthy people under 50.
