This page contains brief details about the drug , it's indication, dosage & administaration, mechanism of action, related brands with strength, warnings and common side effects.
Background and Date of Approval
Yellow fever vaccine belongs to the therapeutic class of immunization agents.
Mechanism of Action of undefined
The yellow fever vaccine functions by introducing a weakened yellow fever virus into the body. This weakened virus triggers an immune response, teaching the immune system to recognize and defend against the virus. In the event of future exposure to the virus, the immune system is prepared to swiftly and effectively combat it, protecting against yellow fever.
Uses of undefined
It is a preventive vaccine that protects individuals from contracting the yellow fever virus. The yellow fever vaccine primarily aims to induce immunity against yellow fever, a potentially severe and life-threatening disease transmitted by mosquitoes. Travelers visiting regions where yellow fever is endemic, healthcare workers in endemic areas, and individuals residing in or near outbreak-prone areas are among those who may receive this vaccine. The vaccine is a crucial tool in public health efforts to prevent the spread of yellow fever and is administered to reduce the risk of infection in at-risk populations.
undefined Drug administaration and Dosage available
The yellow fever vaccine is typically administered via a single subcutaneous (under the skin) injection. This administration route allows the vaccine to enter the bloodstream and stimulate the immune system to develop protection against the yellow fever virus. It is a standard practice to administer the vaccine just under the skin, usually in the upper arm.
Warnings, Precautions and Side Effects of undefined
Although rare, some individuals may experience allergic reactions to components of the yellow fever vaccine, such as eggs, chicken proteins, or gelatin. Signs of an allergic reaction can include hives, difficulty breathing, and swelling of the face, lips, tongue, or throat. In extremely rare cases, severe adverse events, such as severe allergic reactions (anaphylaxis), neurologic reactions, or organ system dysfunction, may occur.
Before receiving the yellow fever vaccine, have a comprehensive discussion with your healthcare provider about your medical history, including allergies, past reactions to vaccines, and any underlying medical conditions. Seek immediate medical attention if any severe allergic reactions occur. If you have a weakened immune system due to medical conditions like HIV/AIDS or immunosuppressive medications, consult your healthcare provider.
The yellow fever vaccine can have side effects, though they are typically mild and short-lived. Common side effects include low-grade fever, headache, muscle aches, fatigue, and soreness at the injection site. Severe adverse events like allergic reactions (anaphylaxis), neurologic reactions, or organ system dysfunction can occur in rare cases.
Word Of Advice
Individuals planning to receive the yellow fever vaccine should consult a healthcare provider experienced in travel medicine for personalized guidance. Precautions include assessing overall health, discussing medical history and medications, considering potential allergies, verifying vaccine availability, adhering to recommended timing, and obtaining an International Certificate of Vaccination. Special attention is warranted for pregnant and breastfeeding individuals, those with weakened immune systems, and individuals with severe allergies. While traveling, it is vital to stay informed about regional vaccination requirements, potential outbreaks, and emergency medical care options.
