-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.

Some reactions may cause general fatigue, a slight fever, or a feeling of tightness in the chest. These signs do not indicate lung damage but rather the body’s effort to produce antibodies. The breathing difficulties reported by some patients may also stem from anxiety or fear of needles, phenomena well-known in the medical field.
