Immunity by vaccination is the only effective one to reduce the serious risk of COVID-19: Gatell

Undersecretary of Health Hugo Lopez-Gatell, explained through an interview the differences between acquiring contagion immunity e vaccination immunity, highlighting the importance of the latter to prevent serious illnesses due to COVID-19.

He noted that the disease immunity is more complete and lasting, referring to any disease, but, said the vaccines allow people to be exposed only to certain components of the virus that allow protection.

“Immunity for vaccines it is limited to some antigens, the proteins capable of producing immunity, of the virus”, he commented.

Therefore, he stressed that “the immune response vaccine-induced is sufficiently potent, complete, and long-lasting to very significantly reduce the likelihood of serious illness, the need for hospitalized and of risk of death”.

However the undersecretary of health pointed out that the vaccine immunity It does not mean that people will not get sick, so it is necessary to take care of yourself.

López-Gatell commented that the immunity generated by ómicron protects from previous variants such as delta; however, he stressed that there is no certainty that it can protect against future strains that may appear.


“The people we already had COVID we are at risk of becoming infected with the omicron variant. If we are vaccinated, we have a greater probability that this reinfection will be from mild way, but what is encouraging is that there are demonstrations that the immunity caused by omicron protects against previous variants”, he commented.

He also emphasized that people should not try to generate immunity by contagion, since they run the risk of becoming more seriously ill, even though they are the omicron variant, so he recommended getting vaccinated and even applying the booster.

Call to get vaccinated

Various experts have already spoken about the importance of vaccines for the prevention of diseases, such as the professor of the Department of Microbiology and Parasitology of the Faculty of Medicine of the ONE, Gabriella Garcia Perez.

“It is necessary that those who have not been vaccinated do so,” he said. In addition, he explained that people who do not get vaccinated are the ones who open up the possibility that these viruses continue to circulate “because they are reservoirs where they can infect and replicate.”

Quoted in a UNAM statement, the specialist recalled that thanks to vaccines, severe diseases have been eradicated national territory such as poliomyelitis, diphtheria and measles.

Finally, he added that even when the vaccines imply a risk, “it is always less than not being vaccinated, because with them we can prevent the disease or prevent it from getting worse”.
