COVID-19 parties young people looking infection could become normal if the virus is not eradicated, a Cambridge immunologist warns: Parties where young people try to catch COVID-19 to gain immunity could become the norm if the virus is not eradicated, according to Paul Lehner, an immunologist from Cambridge, as reported by The Guardian.

Lehner assures that he believes that the new coronavirus will become endemic and people will gain immunity either by vaccinating or passing the disease in youth, which makes him think about the future with optimism, since he points out that young people do not get seriously ill.

That is why the immunologist believes that covid-19 parties will be normalized so that young people are exposed to the coronavirus while their risk is low.

However, there are some critics of this possibility, since, while it is true that the virus is more likely to cause serious illness the older the patient's age, young people are not exempt from danger and the long-term consequences that the virus can cause are unknown.

COVID-19 is proving to cause multi-systemic disorders in a wide variety of patients, including those who do not experience the disease with severe symptoms, so exposure to coronavirus even in youth may be too great a risk given the uncertainty of the sequelae.

In addition, exposure to the virus would aim to achieve immunity in order to be protected against future infections, but in the case of coronavirus it is not yet known how long immunity lasts.

Studies have shown that antibodies generated in response to infection disappear within a few months and, although there is a cellular memory that is vital in the case of COVID-19, cases of reinfection reveal that re-contracting the disease is not impossible.

In addition, responsibility also comes into play, as other experts have warned.

"If a person becomes infected, they may have no symptoms, but they could pass it on to someone else, who will pass it on to someone else, who will then make someone's grandmother or grandfather, a sick uncle or a leukemic child on chemotherapy, get sick and die," said Anthony Fauci, the top infectious disease expert in the United States who is leading the management of the COVID-19 pandemic.

Spaniards, increasingly reluctant to get vaccinated against coronavirus: the reasons why skepticism grows and the answers of experts

Spaniards are increasingly reluctant to get vaccinated, according to data from the survey of the World Health Organization (who) coordinated by the Carlos III Health Institute that tracks the behavior and attitudes of the population related to COVID-19 in our country.

The data referred to the month of September reveal that the number of people willing to get a vaccine against coronavirus is only 43% compared to 70% of respondents who said the same in June.

The figures agree with those found by a similar CIS survey that indicated that today 40.2% of Spaniards are willing to get vaccinated immediately when they have a vaccine compared to 43.8% who would not put it.

The main reasons why the population says they would not put the vaccine are “ " it may have risks to my health” (59%); “I would put a second or third, not the first” (37%) and “I think it will not be effective” (16%).

In addition those who are not concerned about the impact of COVID-19 or believe it is a mild disease are also more reluctant to get vaccinated.

This is what experts say in the face of the skepticism that is waning in the population against vaccines.

That citizens think that the vaccine will not be effective is not entirely unwise. It is "unlikely" that a vaccine will stop the spread completely, said Sir Patrick Vallance, chief scientific adviser to the UK government.

Vallance's opinion coincides with that of several experts who have already expressed that the vaccine will not be the magic solution that the population seems to be waiting for.

The vaccine is only "one more tool" and, "when it exists, we will see what need there is for it," explained Adolfo García-Sastre, director of the Institute of Global Health and Emerging Pathogens linked to the Mount Sinai Hospital in New York, in an interview.

Isabel Sola, senior scientist and co-director along with Luis Rincanes of the coronavirus Laboratory of the National Biotechnology Center (CNB) of the Superior Council of Scientific Research (CSIC), explained that it is likely that the first vaccines that arrive are not one hundred percent effective.

In spite of everything, like Vallance, García-Sastre believes that they will remain useful. The expert acknowledges that, "the more you protect from infection, the better the vaccine", but warns that it does not need to work like this either. "Protecting against disease or reducing contagion would already make sense," he explains.

Such a candidate could reduce the saturation of the health system and avoid the most severe complications of the disease. A flu solution works in a similar way, as it does not completely prevent the spread, but reduces the severity and therefore the symptoms, making people less contagious.

Another aspect that generates distrust is that the development of vaccines is occurring at an accelerated rate in a few months compared to the decade that usually takes.

"It is accelerating because it is a global need," explained Sergio Rodríguez, Managing director of Pfizer Spain, at the smart Business Meeting on the pharmaceutical industry organized by Business Insider Spain.

Rodriguez pointed out that the investment and collaborations between the different actors of the sector and government are unprecedented and have allowed to boost development.

However, he said,"the quality of research is not being diminished." Vaccines that reach the market "are going to be safe," Rodriguez stressed.

"None of the requirements of scientific rigor are failing to be met," insisted the Pfizer CEO.

The only remaining unknown about the vaccine is how long the immunity it induces lasts. "We will not know how long the immunity lasts, because he will not have given time to follow the volunteers for a long time," Sola noted.

Despite this, the scientist also assured that vaccines that have completed these trials will be able to put on the market with the peace of mind that they are "safe and effective"vaccines.

To try to completely eradicate the virus or at least curb its spread considerably, we must bet on the immunization of the population, according to Kingston Mills, immunologist at Trinity College Dublin.

Although questions remain about how the immune system responds, It has been shown that antibodies are generated and that cases of reinfection do not seem to be common.

Like the World Health Organization, Mills questions this practice, since " the consequence of trying to reach that threshold through natural infection will be many more deaths in the at-risk groups: the elderly, people with obesity and those with underlying medical conditions."

Therefore, the next best option is the vaccine, but if a majority of the population is not willing to be vaccinated, the desired herd immunity will not be achieved.

The danger is real, since the trend observed in Spain is being seen in various countries of the world: a global survey conducted by Ipsos indicates that in countries such as Germany, Italy, France or Sweden a third of the population assures that they will not be vaccinated.

” It will be a tragedy that, if we develop safe and effective vaccines against Covid, people will not put them on, " says Scott C Ratzan, a researcher at the school of Public Health at the City University of New York (CUNY SPH) and co-author of another work on the global acceptance of a vaccine published in Nature, as La Vanguardia collects.
