You may be right. But you're not an expert and you're not Fauci. You kept telling us to listen to the experts. Well, I am. I am not listening to you but rather to Dr. Fauci, the expert.
No. You're not listening—you're hearing. You're reacting without understanding what you've heard. You still don't understand what vaccines do and don't do; the difference between a vaccine preventing disease and preventing infection; that there are different levels of immunity conveyed by vaccines; that a variant of a virus like influenza or COVID-19 is just that—a variant of the
same disease. You lack a basic understanding of vaccines and immunization.

Coronavirus: few vaccines prevent infection – here’s why that’s not a problemhttps://theconversation.com/coronavirus-few-vaccines-prevent-infection-heres-why-thats-not-a-problemVaccines are a marvel of medicine. Few interventions can claim to have saved as many lives. But it may surprise you to know that not all vaccines provide the same level of protection. Some vaccines stop you getting symptomatic disease, but others stop you getting infected too. The latter is known as “sterilising immunity”. With sterilising immunity, the virus can’t even gain a toehold in the body because the immune system stops the virus entering cells and replicating.
There is a subtle yet important difference between preventing disease and preventing infection. A vaccine that “just” prevents disease might not stop you from transmitting the disease to others – even if you feel fine. But a vaccine that provides sterilising immunity stops the virus in its tracks.
In an ideal world, all vaccines would induce sterilising immunity. In reality, it is actually extremely difficult to produce vaccines that stop virus infection altogether. Most vaccines that are in routine use today do not achieve this.
The first SARS-CoV-2 vaccines to be licensed have been shown to be highly effective at reducing disease. Despite this, we don’t yet know whether these vaccines can induce sterilising immunity. It is expected that data addressing this question will be available from the ongoing vaccine clinical trials soon. Although even if sterilising immunity is induced initially, this may change over time as immune responses wane and viral evolution occurs.
