The vaccine for any form of flu is a utopia (in fact it is an ideology: an ideal that cannot be achieved, but which is used to achieve a given goal).
The vaccine cannot be created because Coronavirus (the flu virus) changes rapidly, and the vaccine is extremely targeted, and cannot work on the mutated virus. So, as it takes several months to develop a vaccine, it will always be “late” (when the vaccine is released, the next flu epidemic will already be underway, caused by a mutated virus that will no longer be intercepted by that vaccine).
– by observing the maps of the most serious outbreaks of Coronavirus (such as that of Bergamo, Lombrarida, Italy) it is noted that these outbreaks correspond to areas where the institutions have carried out massive vaccination campaigns.
– it should also be borne in mind that the vaccine is significantly less effective for older people (over 70 years of age). [see Article]
