All that you need to know about yellow fever vaccination!

History of vaccine:
Yellow fever vaccine has been there since more than 60years. Although, earlier its use was not much but over the last two decades since the time when number of people are getting infected, yellow fever has become a serious health issue for most of the countries. This is the reason why most of the people are recommended to get yellow fever vaccine.
New York scientists at the Rockefeller Foundation developed a live vaccine 17 D, which was attenuated by a serial passage of the Asibi strain in embryonated chicken eggs.
Who should receive Yellow Fever travel Immunization from NYC?
Yellow fever infection is mostly epidemic in the countries like Africa, Central America and South America, thus for the people who are living there and even passing through these countries they are especially recommended to get themselves vaccinated. Moreover, till the time travelers haven’t shown their vaccination certificate they are not allowed to enter into the countries.
Who should not take yellow fever vaccine?
Although, it is quite important for all the travelers to get themselves vaccinated, if they are heading towards the epidemic zones, but there are few others who are not given yellow fever vaccine. Let’s have a look-
  • Infants- Infants who are under 6 months of age they are not given this vaccine as it would cause a risk of encephalitis (brain inflammation). Preferably, this vaccine is deferred till the time child is at the age of 9 to 12 months.
  • Pregnant women’s- Even the pregnant ladies should not get themselves vaccinated as it would infect their growing fetus, which would eventually effect the growth of baby.
  • Going through treatment- Patients who are going through some treatments like cancer, even they are not given yellow fever vaccine.
  • HIV people- HIV infected people are also not recommended to take this vaccine, as they are already going through one treatment. If in case, they do get yellow fever travel vaccinations from NYC then they might have risk of getting complications for their HIV treatment.
Thus on the whole, the only viable option for all such people is that they should avoid travelling to high risk areas till the time they are not allowed by travel clinic doctor.
Effectiveness of vaccine
Yellow fever vaccine is highly effective vaccine. It affects starts within one week from the time traveler has taken the vaccine. A single dose protects the person for at least 10 years and may be for life time.
Booster vaccination
There are people who have to travel to high risky areas again and again, either for their work or for an outing. Reason could be any, but each time they go they have to get themselves vaccinated. However, some may think that last time they had taken the vaccine then what’s the purpose of taking it again. Answer to the query is simple! Yellow fever vaccine never harms the immune system of a traveler rather it acts as a booster to prevent him or her from the deadly disease.
