Abstract:
Due to the current burden of COVID-19 on public health institutions, increased migration and seasonal touristic traveling, there is an increased risk of epidemic outbreaks of measles, mumps and rubella (MMR). The aim of the present study was to analyze the epidemiological data on MMR immunization coverage and the number of measles cases in 2001−2019 in Croatia and a number of European countries. Results revealed a decreasing trend in vaccination in 2001−2019 throughout Europe. However, Croatia and Hungary still have the highest primary and revaccination coverage, compared to other analyzed countries. The highest number of measles cases was in 2017 in Romania. There was no significant correlation between the percentage of primary vaccination and the number of measles cases (r = −0.0528, p = 0.672), but there was a significant negative correlation between the percentage of revaccination and the number of measles cases (r = −0.445, p < 0.0001). In conclusion, the results of the present study emphasize the necessity to perform a full protocol of vaccination to reach appropriate protection from potential epidemic outbreaks. Furthermore, in the light of present migrations, documenting the migrants’ flow and facilitating vaccination as needed is of utmost importance to prevent future epidemics.
Insights
Measles, mumps, and rubella (MMR) vaccination rates are declining in Europe, increasing epidemic risk. Full vaccination protocols, especially revaccination, are crucial for public health protection against measles outbreaks.
Area of Science:
- Epidemiology
- Public Health
- Immunization
Background:
- Global health challenges like COVID-19, increased migration, and travel heighten the risk of measles, mumps, and rubella (MMR) outbreaks.
- Monitoring MMR immunization coverage and measles incidence is vital for public health preparedness.
Purpose of the Study:
- To analyze epidemiological data on MMR immunization coverage and measles cases in Croatia and other European countries from 2001 to 2019.
- To investigate the correlation between vaccination coverage and measles incidence.
Main Methods:
- Retrospective analysis of epidemiological data on MMR vaccination coverage and measles cases.
- Statistical analysis to determine correlations between vaccination rates and measles incidence.
Main Results:
- A declining trend in MMR vaccination coverage was observed across Europe between 2001 and 2019.
- Croatia and Hungary maintained high primary and revaccination coverage rates compared to other European nations.
- A significant negative correlation was found between revaccination coverage and the number of measles cases (r = -0.445, p < 0.0001), while primary vaccination showed no significant correlation.
Conclusions:
- Completing the full MMR vaccination protocol, including revaccination, is essential for effective protection against measles outbreaks.
- Documenting migrant populations and facilitating timely vaccination are critical public health strategies to prevent future epidemics in the context of ongoing migration.
