Background: Recording real-time data of vaccinations performed, vaccine stocks, and adverse events following immunization is a particularly useful activity in the effective development of any vaccination campaign or vaccination program, guiding the decisions of public health authorities. The aim of this paper is to present the benefits of the National Electronic Registry of Vaccinations in providing useful information for the optimization of healthcare vaccination policies, specifically related to COVID-19 vaccination. Methods: We performed a descriptive study using data available in the reports generated from the National Electronic Registry of Vaccinations regarding COVID-19 vaccinations performed between 27 December 2020 and 31 December 2021. Results: A total of 27,980,270 doses of the COVID-19 vaccine were distributed. Of these, 15,757,638 (56%) were administered in 4545 vaccination centers: 7,882,458 as the 1st dose (50%), 5,878,698 as the 2nd dose (37%), and 1,996,482 as the 3rd dose (13%). More than 25% of the total doses were administered to people over 65 years of age. A total of 41% of the population received at least one dose of the COVID-19 vaccine. A total of 4083 adverse events following immunization were reported. Conclusions: The existence of a National Electronic Registry of Vaccinations containing accurate information on vaccinations performed in Romania offers the opportunity to obtain a clear picture of vaccination status that will significantly contribute to the optimization of vaccination strategies and programs.

Foodborne botulism, caused by ingestion of pre-formed botulinum neurotoxin, is the most common form of botulism. While large outbreaks linked to commercial foods are rare, smaller outbreaks associated with home-processed products are more frequent, reflecting local dietary habits and traditional preservation practices. The aim of this paper is to provide a public health overview of reported foodborne botulism outbreaks in Romania over an 18-year period to raise awareness among clinicians and public health officials. Between 2007 and 2024, a total of 337 foodborne botulism cases were reported in Romania, of which 43% (147) were related to 55 outbreaks (median number of cases per outbreak: 2; IQR: 2–3). Most outbreaks were reported in Bihor County (11 outbreaks with 29 cases) and its neighboring county, Satu Mare (seven outbreaks, accounting for a total number of 20 cases). Outbreak-related cases were observed in younger persons with a median age of 31 years (compared to 45 years for sporadic cases) and were statistically significantly associated with consumption of pork products (p < 0.001). Fifteen deaths occurred (case fatality ratio: 4%), including three outbreak-related cases (case fatality ratio: 2%). These findings highlight the ongoing public health challenge of foodborne botulism in Romania and the need for robust surveillance, targeted educational initiatives in high-incidence counties to deliver information about safe food preparation and preservation practices, and the continuous availability of botulinum antitoxin supplies.
