Why do we call it a COVID-19 vaccine if it only seems to be a drug to boost the immune system in the short term? Is it a paradigm shift?

 Wow… Are you telling me that the "alleged vaccine" for COVID-19 is a drug that stimulates the production of antibodies against a virus?

Well, you're right, but it just so happens that vaccines do exactly that.

The only thing that really changes is the way to get it. Traditional vaccines use attenuated viruses or parts of the virus to stimulate the immune system, the new RNA vaccines do the same thing our immune system does.

Our immune system after fighting a virus (or vaccine) stores in RNA how proteins are synthesized that bind to the surface of the virus leaving it inactive. RNA vaccines skip that step and directly provide the RNA needed for it.

And there are vaccines that last longer, there are vaccines that last less. This is not something that magically appeared with COVID-19. Flu vaccines have been effective for decades and look where the flu is a coronavirus like COVID-19.

Flu again like that COVID-19 has a high mutation rate causing new strains to appear annually.

Are you starting to see the similarities?

The funny thing is to see herds of fools that for decades have seen how the flu mutates annually and its vaccines have a limited efficacy over time, now say that the vaccines against COVID-19 "are not vaccines" because they use a new technique and they fight a virus that looks like it behaves like one that has been bothering us for thousands of years.

And do not believe that the flu is harmless, only in Spain it kills thousands of people a year. Many more than traffic accidents.
