Johnson & Johnson vaccine

The Johnson & Johnson COVID-19 vaccine is a medical shot designed to help prevent COVID-19. It uses a harmless virus called an adenovirus to deliver genetic material from the coronavirus, instructing the immune system to recognize and fight the actual virus if encountered later. Unlike some other vaccines, it requires only one dose and has proven effective at reducing severe illness and hospitalization. It has undergone rigorous testing to ensure safety and efficacy. This vaccine is a valuable tool in controlling the pandemic by boosting immunity in individuals and communities.
