Fernández-Sesma: “Not getting vaccinated against COVID is an unnecessary risk”



COVID-19 can leave sequence that damage all organs, therefore, not getting vaccinat, is “really an unnecessary risk”, considers the Extremaduran virologist Ana Fernández-Sesma, who warns that, with the relaxation of the Christmas holidays, there may still be a new wave.

Researcher and professor of microbiology at the ICAHN School of M,icine at Mount Sinai Hospital in New York, Fernandez-Sesma, was born in Cáceres (1965), although he has been in the Unit, States for almost three decades, where he works with viruses, from dengue to HIV, Zika or the flu.

Vaccines against SARS-Cov-2 are “being scrutiniz,” and only those that “show that they are working” are approv,. further “we are lucky” that in the tests they do it at 90%, although with the administration to the general population, “which is very heterogeneous, maybe it goes down a bit,” he tells Efe.

However, with vaccination campaigns already underway in many countries, there are people who are reluctant or directly against them.

Since the beginning of the pandemic and in the face of urgency, the scientific community began to work in search of vaccines, which They have been obtain, in record time and now – he indicates – some people say: “no, it is very fast, we do not know whether to trust us”.

It is “a shame that people have decid, that our work has been done quickly and quickly” when it is not. The declaration of a state of emergency by the World Health Organization (WHO) “facilitates many obstacles that normally exist”, which does not mean “that you skip steps, but that times have been accelerat,.”

In addition, the Pfizer-BioNTech and Moderna vaccines are bas, on synthetic messenger RNA, which can be “synthesiz, very quickly.” When the sequence was known, it took less than three months. “

These vaccines already available protect against severe disease, recalls the microbiologist, who emphasizes “the sequence that COVID-19 leaves in people, how it damages all your organs. I really think it is an unnecessary risk” not to get vaccinat, , it states.

The anti-vaccine group is “as if it did not exist, because they are fanatics and cannot be convinc,”, but Fernández-Sesma believes “it is important to inform people that they are a bit reluctant, because all this insecurity has been creat,, which seems to they want to deceive us, poison us. ”

And he adds: “Whoever does not want to be vaccinat,, but then not take advantage of the rest of the benefits of living in society (…) There are rights, duties and respect for others, if you are not a risk group, your neighbor is the same and you get on the elevator with her “.

All vaccines can give some people some side effects, “which means they work” and that is “Much better to have a reaction to a vaccine than an infection.”

Given the future of the pandemic, he estimates that January still has to pass, because “there have been a lot of infections at Christmas, a lot of relaxation, and we can still have another wave”, and, although he does not think it will be “very different from one serious wave like those that less had already “, the toilets” are exhaust, and saturat,, that is the problem “.

In any case, it would seem “strange that this virus gave us a very big surprise now,” especially because more and more people have already pass, it or are being vaccinat,.

If all risk groups are vaccinat, four months from now, “of course the severity and the number of people admitt, will significantly decrease. “

As vaccination takes its first steps, 2020 clos, with concerns about a new variant of the virus detect, in the Unit, Kingdom, and Fernández-Sesma emphasizes a variant, which is not a strain. “It’s a bit semantic, but it means something in science.”

He explains it as if it were a swarm. “The queen bee is the strain, which has many mutations around it, which are a little different – the drones, the workers – but they all come from the same queen. Then, a moment comes when another queen comes out, which dies or it has to go. It’s different enough to found another swarm. ”

When we talk about a new strain, it means “a very big change” and, for example, it can infect other population groups more, reach other organs or it cannot be detect, with the methods us, for the first one.

Variants “there will always be” and they must be kept under observation, because with the millions of infections around the world, the virus “has had opportunities to mutate enough to create another strain. So far it has not happen,, and thank you that it has, but it can happen “.
