Expert explains how this happens and why it is so important to be up to date with vaccinations

Vaccination has many more benefits than you might think. Recent studies have shown that, in addition to preventing infections for which they were created to fight, vaccines still may indirectly reduce the risk of heart disease from a phenomenon known as heterologous and epigenetic immunity.

“When you take the flu vaccine, you are training your immune system to react better against that disease, but it takes advantage of this training to react better to other things”, explains infectious disease specialist Rodrigo Lins, from the State Infectious Diseases Society. from Rio de Janeiro.



What is the relationship between diseases

According to the doctor, the body learns to better fight infectious agentsgenerating a lower inflammatory response during the process and, consequently, preventing diseases that are based on this inflammation.

Just don’t forget that, in general, the inflammatory process is natural and beneficial for the body, as it helps in healing and fighting pathogens. The problem arises when the inflammation becomes chronic and does not go away after the body has recovered. In this case, the cells that are supposed to protect the organs start attacking them.

Often, it is not known why this change in behavior occurs. The fact is that some external factors can favor it, such as frequent intake of fatty foods, inhalation of toxic substances from cigarettes and hard battles against infectious agents.

The role of vaccination

According to infectious disease specialist Rodrigo Lins, a study published in 2021 in Journal of the American Heart Association showed that the annual use of the flu vaccine may be able to reduce mortality from cardiovascular complications by a very significant amount.



Despite the positive data, the expert warns: “This phenomenon is not a specific vaccine for a specific disease. Are all the vaccine stimuli you receive throughout your life that contribute to a healthy aging of the body and the immune system”.

For him, this advantage is like “a beautiful icing on the cake” of the habit of vaccinating, which already directly guarantees protection against dangerous diseases such as measles, rubella, meningitis, tuberculosis and COVID-19. Therefore, it is essential to have your vaccination card up to date, even in adulthood.
