After the outbreaks in Europe and the United States, it's now our country's turn to suffer the first measles outbreaks since the pandemic. Although our country has a high vaccination coverage for the first dose (97.2%), the coverage for the second dose drops to 93.2%, well below the stated target of 95% necessary to contain the disease. This indicates that we cannot relax regarding vaccination recommendations and the importance of completing the two-dose regimen to keep this extremely contagious virus at bay, which also has a very dangerous immunological effect known as "immune amnesia." This virus infects immune memory cells, "resetting" all the acquired memory up to that point in the individual, making them more susceptible to other infections due to this temporary loss of memory.
Therefore, it is crucial to reinforce the importance of vaccination so that diseases that had been forgotten do not return due to the relaxation resulting from the perception of low risk.
