Types of vaccines for COVID-19

Vaccines train your immune system using a harmless form of the virus, SARS-CoV-2, which causes COVID-19. Vaccines stimulate an immune response without causing illness.

Maintaining antibodies in the blood requires creating certain long-lasting immune cells – but this doesn’t always happen. by Steven Smith The goal of the COVID-19 vaccines being rolled out worldwide is to stimulate our immune systems into creating a protective response against the coronavirus, particularly by generating antibodies. These antibodies then circulate in our blood until needed […]
