Vaccine Approval: A Revolutionary Step Forward
Here’s a summary of the key points from the provided text:
New mRNA Vaccine Trial: A new mRNA vaccine is being tested on people who have had Stage III melanoma (cancer surgically removed, but high risk of relapse due to possibly remaining cancer cells).
Stage III Melanoma: This stage involves cancer affecting the lymph nodes. Stage IV involves metastases (cancer spreading).
Vaccine Effectiveness & Stage: The vaccine appears less effective in more advanced stages (III & IV) as the cancer becomes more diverse, limiting the impact of a targeted immune response.
Targeted Use: Researchers hope to use the vaccine on patients before their melanoma reaches Stage III, as the chances of success are higher. Most melanomas diagnosed in switzerland are Stage I or II, wich have high survival rates, but relapses still occur.
Prevention is Key: The best approach is to prevent skin cancer through sun protection:
Avoid sun exposure when the UV index is high.
Use hats, sunglasses, clothing, and parasols.
Apply sunscreen to exposed skin.
Stay in the shade between 11 am and 3 pm.
Avoid tanning beds.
UV Damage: UV rays damage DNA in cells, and while the body can repair some damage, some cells can become cancerous.
