What is Yellow Fever Vaccine?
Yellow Fever Vaccine Description:
Yellow fever vaccine is recommended for individuals planning to live in or travel to regions where yellow fever is prevalent or those at high risk of virus exposure.
Vaccine Purpose:
This vaccine aids in preventing yellow fever by exposing the recipient to a small virus dose, prompting the body to develop immunity. It does not treat an existing active infection.
Vaccination Timing:
Administer the vaccine at least 10 days before potential virus exposure in relevant areas. It is also advised for those working in research laboratories at risk of exposure through accidents or inhalation.
Effectiveness:
Similar to any vaccine, yellow fever vaccine’s protection varies among individuals.
Yellow Fever Vaccine Side Effects
Allergic Reaction:
Seek emergency medical help for signs of an allergic reaction: hives, wheezing, chest tightness, difficulty breathing, or swelling of the face, lips, tongue, or throat.
Booster Doses:
Avoid booster vaccines if a life-threatening allergic reaction occurred after the initial dose. Monitor and report side effects within 30 days for potential booster considerations.
Emergency Symptoms After Vaccination:
Contact a healthcare provider if symptoms resembling yellow fever emerge within 10 days post-vaccination, such as fever, headache, confusion, extreme tiredness, muscle pain, weakness, light-headedness, bruising, unusual bleeding, decreased urination, vomiting, loss of appetite, or jaundice.
Serious Side Effects:
Rare but serious side effects, including high fever, seizures, neurological issues, severe pain, or loss of bladder or bowel control, warrant immediate medical attention.
Common Side Effects:
Frequent side effects may include fever, vomiting, nausea, headache, joint or muscle pain, tiredness, weakness, or pain, redness, swelling, or induration at the injection site.
Post-Vaccination Certificate:
A yellow card certifying vaccination is provided, valid 10 days after vaccination for a duration of 10 years, often required for entry into certain countries.
Warnings
Booster Vaccines:
Avoid booster vaccines after a life-threatening allergic reaction to the initial shot.
Contraindications:
Do not receive the vaccine if allergic to yellow fever vaccine components, eggs, chicken proteins, diagnosed with cancer, leukemia, lymphoma, immune system weakness, myasthenia gravis, thymus gland disorders, or thymus gland removal. Children under 9 months should not receive the vaccine.
Illness Considerations:
If severely ill, wait until recovery before vaccination. Pregnant individuals with high yellow fever exposure risk may receive the vaccine after assessing risks and benefits.
Breastfeeding:
Consult a doctor regarding breastfeeding safety after vaccination, especially if the child is under 9 months.
How is Yellow Fever Vaccine Administered?
Administration Method:
The vaccine is injected subcutaneously by a healthcare provider.
Booster Doses:
One dose generally offers long-lasting protection. Booster doses may be considered after 10 years for sustained risk of yellow fever exposure.
Dosage Information:
Adults receive 0.5 mL subcutaneously. Pediatric doses follow age-appropriate guidelines.
Missed Dose and Overdose:
Consult a doctor if receiving the vaccine less than 10 days before potential virus exposure. Overdose is unlikely.
Precautions Before/After Vaccination
Avoidance:
Follow instructions on food, beverages, and activities before and after vaccination.
Drug Interactions:
Inform the doctor of recent vaccines or treatments weakening the immune system.
Conclusion:
Yellow fever vaccine is crucial for those at risk of exposure. Understanding its administration, possible side effects, and necessary precautions ensures effective and safe utilization.
