Did you read the article in its entirety? Or did you just cherry pick data to support some misplaced right wing agenda?
It is difficult, highly technical reading. In laymen's terms, our bodies have evolved in a certain way to deal with short term, rapidly mutating, respiratory viruses. Basically, rather than developing a central immunity, it deals with the symptoms and rides out the storm. That is oversimplified, but appears to be the gist.
We do not presently have a general vaccine to control the flu per se. That does not mean our annual flu vaccines have no value. Ditto the Covid vaccines..
Meanwhile, they are not giving up. There are multiple promising lines of inquiry with serious obstacles to overcome.
Yes, the article is technical. The explanation of why smallpox and other vaccines are effective as opposed to the efficacy of a vaccine for a respiratory virus was interesting.
Cherry picking, as you call it, a rather damning statement about the efficacy of vaccines vs mucosal virus infections was simply highlighting a statement that was in a study co-authored by Fauci.
Fauci, who was happy to get in front of tv cameras to tell the country how great the vaccine was at everything, is now co-authoring a mea culpa study down playing the efficacy of mucosal respiratory virus vaccines.
Tell me again why Bhattacharya, Kuldorff and others were ridiculed as 'fringe epidemiologists'.
On 2nd thought, don't bother.
"Meanwhile, they are not giving up. There are multiple promising lines of inquiry with serious obstacles to overcome."This should scare you. Do we get another pandemic to test out a promising line of inquiry ?
