COVID-19 Vaccine and Lung Health: What
Science Says
Since the start of COVID-19 vaccination campaigns, one question has frequently arisen: can the vaccine harm the lungs? Some people report experiencing shortness of breath or difficulty breathing after their injection. These concerns deserve a clear explanation, as lung health remains a major concern since the pandemic.

COVID-19 vaccines, whether mRNA or viral vector-based, work by stimulating the immune system. They do not contain any agents that can directly attack lung tissue. When a person experiences effects after the injection, it is most often a normal immune response. This response indicates that the body is learning to recognize the virus in order to better defend itself later.
