Abstract: Vaccines are a safe and effective way for protection against severe disease and 
possible serious health consequences. The vaccination process gives individual protection but 
the goal of achieving high vaccination coverage in the population was to limit the spread of 
COVID-19.
The purpose of the present study is to prove the correlation between the low number of 
vaccinated patients who sought medical help in the Emergency Department of UMHAT Burgas
and more specifically the Triage Center and their need for hospitalization due to the unfolded 
severe clinical picture of the disease.
As the research method was used the interview which consisted of filling in a Checklist made 
up of six components with two possible answers.
The results of processing the obtained data showed a real correlation between the low number 
of vaccinated patients and the need for hospitalization for active treatment.
In conclusion we believe that vaccines against COVID-19 are the most effective means to 
reduce the number of severe cases of COVID-19, hospitalizations and mortality.
