I'm fully vaccinated against measles, polio and small pox and I've never needed a booster, why is that? But in the last year I've been stabbed three times for covid, why is that? Because there's no covid vaccine, ding dong! At best the shot is an prophylatic immune therapy.
You don't understand immunology at all. It's a tough subject. It's harder than designing a roof. Way, way harder. That might be why, despite your protests, you and Cultellus do as you are told and get the shots anyway. That's good.
There is a Covid vaccine, for starters. You should look up the definition of a vaccine and correct your understanding. Then look up the term "sterilization immunity". Achieving sterilization immunity might be the holy grail of vaccination, but it is not required to count as a vaccination.
Seasonal flu shots, which are far less effective, are still vaccinations.
The best we can do so far, is to present the antigen or segments of antigen protein to our immune system and hope our immune systems are capable of responding. There's some trial and error to maximize the response, but our immune systems can only do what the Lord Jesus designed them to do.
I'm sorry that if back when our garbage president dismantled the CDC and shrugged off the rising probability of a pandemic when liberals like Bill Gates were publicly expressing worry over an increasingly dangerous situation -- and the danger is still increasing - thinking, "who cares, we'll just make a shot like we did for polio and small pox when the time comes". That's your fail.
Social distancing has likely already begun to flatten the curve...Continue to research good antivirals and vaccine candidates. Make everyone wear masks. -- J.D. Vance
