COVID-19 vaccination involves receiving a shot to help protect against the COVID-19 virus. Vaccines work by training the body's immune system to recognize and fight the virus if exposed. Several vaccines have been developed and authorized for emergency use, including those from Pfizer-BioNTech, Moderna, and Johnson & Johnson. Getting vaccinated can reduce the risk of severe illness, hospitalization, and death from COVID-19. Health authorities recommend vaccination for eligible individuals to help control the spread of the virus and protect public health. Vaccination is a key tool in managing the ongoing pandemic.
