Vaccination to prevent measles in Mexico City will continue intensively and herd immunity is expected to be achieved by the end of this month, said Nadine Gasman, the local Secretary of Health.

In a press conference, the official reported that during Shakira ‘s concert, three vaccination stations were set up where 1,916 people received their dose.

The head of the Health Secretariat reminded everyone that the goal for Mexico City is to vaccinate 2.04 million people against the disease in order to achieve herd immunity; once that goal is reached, the administration will continue the campaign to encourage people to go to the 150 vaccination centers to get vaccinated.

To date, health personnel have administered 1,614,915 doses; since the campaign reinforcement began on February 8, 693,829 doses have been administered, and 17,291 were administered on Sunday.

The Secretary of Health commented that there are 418 confirmed cases, 64 of which are people who live in the State of Mexico, and announced that after the weekend there was a registration of six more sick people.

She stated that two cases of deaths possibly related to measles are still under investigation; one is that of a three-year-old girl, who arrived at the hospital on February 22 of this year with clinical death and when the medical history was taken with the parents it was determined that it was a death with epidemiological relevance.

The second case, registered on January 28, 2025, is a two-month-old baby who arrived sick with pneumonia and died, but experts are also reviewing the matter for epidemiological reasons.

The official presented a table to show that the highest incidence of measles is in the Cuauhtémoc borough, followed by Cuajimalpa and Gustavo A. Madero.
