The microbiologist Sergi Maicas considers that most people who have been infected with coronaviruses could be immunized against future infections and in those cases where they are infected a second time, the symptoms would be “much milder”.
Maicas, full professor of the Microbiology department of the University of Valencia (UV) and director of the Master in molecular, cellular and genetic biology, assures in an interview with the EFE Agency that what the SARS-CoV-2 is doing “is not far a lot of what other viruses do. “
“There are many coronaviruses circulating, among them those that cause us many of the colds on a regular basis,” says the expert, who adds that each time a new one arises “the first time we catch it, it completely catches our immune system off guard.”
Although there is a percentage of the population that does not exceed it, “the vast majority pass it as a more or less severe cold, and with an immunization that will make our immune system take charge of these viruses in the next wave and the symptoms will be more mild. “
“It is foreseeable that when summer arrives the coronavirus will decrease in intensity and ‘go on vacation’ but it will return, I very much doubt that this will end in two months. A second wave will return but a large part of the population will be caught immunized, although it could There will be casualties again among older people who have not passed it. “
Sergi Maicas considers that the new SARS-CoV-2 coronavirus, which causes COVID-19, “should a priori immunize us” and in the case of a second wave “should not affect us as much statistically.”
He indicates that this coronavirus will mutate because “all viruses mutate, it is a fact that we cannot change because, unlike the vast majority of organisms on the planet, they have less effective control over the copies they make of themselves.”
He clarifies that these mutations often lead the virus to adapt and become less serious and harmful to its host, although the possibility of transmission increases. “With a simple cold you keep going out and going to work, that favors that virus that has mutated into something softer is transmitted more.”
“Once the virus jumps from the animal and enters the human species, it must adapt to persist and stay in it for life and can only do so if it passes asymptomatically, if it does not bother much,” explains the microbiologist.
He adds that immunization to a virus occurs because part of it is recognized by our immune system and antibodies are generated, some of which act quickly and manage to “knock it out and eliminate it”, so if you have the same disease again “it is milder or almost asymptomatic. “
In addition to this natural immunization, a person can be immunized through a vaccine, although Maicas warns that it can take between five and ten years to develop one with all the guarantees.
In this case, and given the urgency of the pandemic, it could take a year and a half or two years, he says, adding that a vaccine that is not well tested could have other side effects.
Those vaccines, he points out, will be to immunize children and not adults, since it would only make sense to vaccinate an adult if it were known for sure that the disease had not passed, and if it had “already been vaccinated of natural form”.
After warning that there are “more viruses than people”, he considers that after this pandemic “many more will come, they do it regularly and some have been very serious, such as the Spanish flu that caused between 10 and 30 million deaths ”
It also warns of other types of pandemics caused by bacteria, also causing thousands of deaths, and indicates that in 2040 or 2050, when “we do not have antibiotics to combat superbug attacks, we think that some may occur.”
