“…Progress has also been reflected in the decline in reported rubella cases, including a 48% decrease during 2012-2019, with a further decrease in 2020. The extent to which rubella transmission declined in 2020 is unclear, however, because fewer reported cases might reflect the impact of COVID-19 mitigation measures or an underreporting of cases in 2020 because of reductions in health care-seeking behavior from patients, health facility availability and reporting, or overall pandemic-related health system disruptions (9). The increase in the number of reported CRS cases during 2012-2020 reflects improved surveillance in several populous countries that initiated CRS surveillance after 2012, rather than an increase in rubella among susceptible pregnant women and CRS in their infants.…”

“…Therefore, the maintenance of high immunization coverage is essential, and the existence of sufficient immunization coverage must be strictly monitored. Moreover, since the onset of the COVID-19 pandemic, the already suboptimal measles surveillance has worsened [22]. According to a recent CDC MMWR report, no WHO region has achieved and maintained measles elimination [22].…”

(1) Background: Measles immunization gap(s) raise the concern of potential outbreaks. Both Croatia and Hungary are situated in the vicinity of measles-endemic countries. Potentially compromised immunization activities due to the COVID-19 surge is a ground for concern. Our aim was to compare age-stratified seroprevalence results in the cross-border region. (2) Methods: Anti-MMR specific antibody levels (IgG) of 950 anonymous Croatian samples were compared with previous Hungarian results (n > 3500 samples), and former Croatian seroprevalence data (n = 1205). Seropositivity ratios were determined using our self-developed anti-MMR indirect ELISA (Euroimmun IgG ELISA kits were used as control). (3) Results: Measured seropositivity ratios of the Croatian samples were largely overlapping with our earlier published Hungarian data (the lowest seropositivity ratios were measured among individuals of 34–43 years of age with 78% of seropositivity) and are in accordance with earlier published data of Croatian researchers. (4) Conclusion: Although the epidemiological histories of the two countries are different, analogies in age-specific measles susceptibility have been discovered. We suggest that besides the potential coincidence in vaccination ineffectiveness, the inherent biological dynamics of vaccination-based humoral protection might have also contributed to the experienced similarities. Our findings may also serve as a lesson regarding the current anti-COVID-19 vaccination strategy.

“…Regardless of the immense progress, several large scale measles outbreaks have recently been reported in countries with moderate to high vaccine uptake. Countries experiencing outbreaks [3] , [4] , prior to the COVID-19 pandemic imposing severe restriction in terms of social interactions, include many European countries such as Romania (3,900 reported cases in 2019), France (2,637 in 2019), Italy (1,623 in 2019), Czech Republic (590 in 2019) and Poland (1,367 in 2019) [5] , [6] . Moreover, in Ukraine there were over 57,000 measles cases in 2019 [7] .…”
