vakcína COVID-19

The term „vakcína COVID-19“ refers to vaccines developed to prevent COVID-19, a disease caused by the coronavirus SARS-CoV-2. These vaccines stimulate the immune system to recognize and fight the virus, thereby reducing the likelihood of severe illness, hospitalization, or death from COVID-19. Various types of COVID-19 vaccines have been developed, including mRNA-based vaccines (such as those from Pfizer-BioNTech and Moderna), viral vector vaccines (such as Johnson & Johnson and AstraZeneca), and protein subunit vaccines. The deployment of COVID-19 vaccines has been a crucial global public health response to the pandemic, aiming to achieve herd immunity and control the spread of the virus. Vaccination campaigns have been implemented worldwide to ensure broad access and encourage uptake among populations.
