The Covid virus is here to stay, although it is “almost impossible” for it to become more virulent

The virus that causes covid-19el SARS CoV-2, “has come to stay and, unless a very different variant appears, which again forces confinement and the collapse of hospitals, it will become one more and join the group of autumn respiratory viruses and winter colds”.

This explains it the scientist and specialist in Infectious Diseases and Clinical Genetics, Vicente Sorianowho maintains that “the pandemic is subsiding, fortunately, and the end of the tunnel is already in sight because diagnosed cases and severe cases requiring hospitalization are falling globally“, thanks to vaccination.

It is very difficultalmost impossible, let a variant appear very different from the coronavirus, which escapes everything, that it be much more virulent and that it block hospitals again“, adds this researcher and teacher, who currently directs the Medical Center of the International University of La Rioja (UNIR) and is vice-dean of its Faculty of Health.

With an eye toward fall and winter, understands that it will be a year of covid-19 “much better than the first two and, although from the point of view of medicine, other things are going to take over”, the fight against covid-19 “is on track and its impact is going to be less and less. It’s predictable.”

there will be no pandemic

He emphasizes, however, thatthere will be small shots of infections, and other types of viruses and bacteria will be present“, as is the case of Ebola, which “is having a small outbreak in West Africa, or monkeypox, which in four months has generated 65,000 confirmed cases worldwide”, but stresses that “there will not be a pandemic in the sense of covid-19 or HIV (AIDS) because we have a vaccine and antivirals”.

Monkeypox or the resurgence of Ebola are triggers of infections on a Planet in which “8 billion people live and, in many places, there is a lot of contact with animal reservoirs, which have their viruses and can jump to the human species periodically,” he says.

About the fourth dose of the vaccine against covid-19, which the autonomous communities begin to inoculate tomorrowmonday, in over 80 years of age and people with serious underlying pathologiesmaintains that its update with the Ómicron variant has been a success, just as it values ​​​​that it is inoculated, at the same time, with that of the flu.

Booster dose for those under 60 is debatable

Soriano, who has also been an advisor to the World Health Organizationensures that currently the scientific medical evidence in favor of the fourth dose providing benefits to people under 60 is “debatable”who have already received the first three doses and who do not have a serious underlying pathology, nor are they transplanted, diabetic or obese.

“It would also be necessary to demonstrate -he adds- that between 50 and 60 years without risk pathologies the fourth dose provides a benefit, which has not been demonstrated and, below 50, even less”.

It also ensures that “immunity against covid-19 is temporary” and, therefore, “the vaccine and its booster doses are not the Hepatitis B or Tetanus vaccines”, but rather “it is more like the flu, which protects more partially and is needed a booster dose.

Global immunity, not yet

On the possibility of selecting a global immunity with universal vaccines, he explains that “viruses have great biological diversity and, with a single vaccine, it is very difficult to find a panacea“That protects against all variants. It happened with smallpox and little else. Even with polio, type 2 has been eradicated, but not type 1.”

I wish! we had a way to select a global immunity, but, at the moment, it does not seem that it will happen in the short term“, so “we have to play with vaccines adapted to what is currently circulating”, concludes this specialist.
