Spain has entered a scenario of high risk of contagion by the coronavirus. The current average incidence, according to data provided by the Ministry of Health (this Friday), is already 323 cases per 100,000 inhabitants. The scene, a few days before Christmas, appears worrying. The doctor Marcos Lopez Hoyos, President of the Spanish Society of Immunology (SEI), head of the immunology department of the Marqués de Valdecilla University Hospital of Santander and scientific director of the IDIVAL Research Institute talks with EL PERIÓDICO DE ESPAÑA, a newspaper belonging to the same communication group as this media, about the scenario in which our country enters just before the holidays and the reasons why infections are increasing and hospital pressure continues to increase in Spain despite the fact that 90% of the target population has been vaccinated.

The sixth wave of the coronavirus continues to grow despite the fact that each percentage of vaccinated in our country is 90%. How should it be interpreted?Vaccines stop infection because they reduce the spread of the virus, but in no case do they sterilize, so they do not eliminate the possibility of infection, what they eliminate is the possibility of disease. severe, both in the first and second doses, as well as even in the third dose. What we’re doing is inducing an immune response that will prevent disease, but not infection and contagion, and that’s very important for people to know.Even with a third booster dose?As for the third dose, on the few data that exist, because there is still very little vaccinated population, we have, for example, those of Israel. In this country, a study showed that in vaccinated patients they significantly reduced mortality. In addition, I insist, the rise of the infection in Spain, at the third dose, has not yet had time to analyze it. If we are talking about a specific case, like the one that happened with the health workers in Malaga (who already had the third dose of the vaccine against the covid) there was no time for it to take effect because otherwise, I was wrong, they had put it a week before, with which there was no room for there to be a sufficient immune response.So, yes, we must think that this third dose is effective.The third dose is mainly given to populations which had not responded well to the previous two. In fact, the third dose is now offered as a booster (currently it is given to social health workers and people over the age of 60) but initially it was used to supplement vaccination in groups such as transplant recipients or patients. the elderly who had not responded to the previous two, which was done to complete the model to see if they could respond. It is important to remember.

“The more we strengthen the immune response, the more difficult we will put it on the virus and the possibility of dissemination is more difficult. Let it be clear “

In any case, back to the increase in infections in Spain. Has being vaccinated given us false security against the virus?What we want is to vaccinate people to prevent disease. Infection is also somewhat reduced, but the effect on infectivity is not so clear. With what we’re going to have people even with third dose infections. Even if it is true that the more we strengthen the immune response, the more difficult it is, we will put it on the virus and the possibility of dissemination is more difficult. Let it be clear. So go ahead with the vaccination.And is this message one that may not be clear among the population?People think, “I have been vaccinated and I am going to take off my mask because I am not going to be infected. No, it’s not like that. We are here to insist: don’t trust yourself, that the vaccine will protect you from disease, but not completely from infection. Not at all. I insist: they reduce, but they do not prevent infection. What prevents it is being with a mask, not having intimate contact between non-cohabitants, spaces with ventilation … And this is the message that must be sent this Christmas. Vaccines do not sterilize; that is, they remove or kill the virus. In this case, they don’t. What they do is stimulate the immune response. We know they reduce mortality by up to 40% more than in unvaccinated patients, but if infected, this effect is not as clear. In addition, when the vaccinated person is infected, they transmit the same viral load as an unvaccinated person.

“If there are today 35 million people vaccinated in Spain, if a hundred of this number enter, it is not the same effect as if a hundred of the other 13 million who are not vaccinated enter”

With the current incidence in Spain, what data should be considered when talking about the effect of vaccination?At a time when people are vaccinated and, when they are infected, are sometimes asymptomatic, it is more important to manage data on sickness hospitalization and intensive care admissions than data on infected people. The higher the number, the more hospital pressure increases. Increases in infections do not always come with increased income. When we talk about the same number of immunized as non-immune detainees, it is because the data is poorly put into perspective. You have to look at the percentage of vaccinated people who enter, compared to those who have not received their doses. If today there are 35 million people immune in Spain, if a hundred of this number enter, it is not the same effect as if a hundred of the other 13 million who are not immune enter.
