Yellow fever has been making a comeback in recent decades because we’ve struggled to control the insects that spread the disease and haven’t vaccinated as we should. This poses a constant threat to people in large tropical cities and travellers to these areas.
We’ll delve into the history of the yellow fever vaccine, its safety, who should avoid it, and efforts to improve it.
The Yellow Fever-17D vaccine is quite effective. While it may cause a mild infection in some, it provides protection to 99% of those who receive it. However, it’s not suitable for everyone, particularly the elderly and those with weakened immune systems. Another challenge is the limited ability to produce the vaccine quickly in large quantities. This underscores the need for further research to ensure a sufficient supply of this highly effective and safe vaccine.
In summary, the yellow fever vaccine is an important tool in the fight against this disease. While it may not be a perfect fit for everyone, it plays a crucial role in saving lives. Continued research will help improve its availability and effectiveness.
