The authors report two cases of Guillain-Barré Syndrome (GBS) occurred during a national measles vaccination campaign in Izmir, Turkey. Among more than 325,000 vaccine recipients, only 2 cases of GBS were observed within the 10-week risk period. These cases yielded an incidence of 0.615 per 100,000 vaccine doses. The authors think that association between measles vaccination and GBS is coincidental, rather than causal. However, an epidemiological evaluation in Turkey is needed to clearly show that there is no causal association between measles vaccination and GBS.

Background: Measles, an ongoing public health concern, demands continuous molecular surveillance and virus characterization for elimination. Despite Iran achieving measles elimination status in 2019 through robust molecular testing and vaccination, the COVID-19 pandemic disrupted global vaccination efforts, leading to increased measles-related morbidity and mortality. This study aims to overview measles virus serological and molecular traits in Iran from 1st January 2021 to 30th April 2023.

The AEP 2025 Vaccination and Immunization Schedule recommended for children, adolescents and pregnant women residing in Spain features the following novelties: Due to the increase in measles cases and outbreaks in recent years, we recommend advancing the second dose of measles, mumps and rubella (MMR) vaccine to 2 years of age. As a consequence of the above, since many autonomous communities (ACs) use the quadrivalent vaccine for the second dose of MMR and varicella vaccines, we recommend, for all ACs, advancing the second dose of varicella vaccine to 2 years of age. Due to the very significant increase in cases of pertussis since late 2023 and especially in 2024, we recommend advancing the dose of Tdap given in adolescence to 10-12 years of age.
