US facing shortage of yellow fever vaccine for travelers
Americans who need a yellow fever shot for travel may soon have a harder time getting the vaccine. The yellow fever virus is spread by the same mosquito that transmits other tropical diseases, including Zika. Officials are bringing in another vaccine that's used in other countries but it will be available at far fewer clinics. The vaccine is recommended for travelers to certain areas in South America and Africa, and about 20 countries require proof of vaccination for entry. A manufacturing issue has created a shortage of the only vaccine licensed in the U.S.The United States is facing a shortage of yellow fever vaccine that could stretch into next year, the Centers for Disease Control and Prevention warned Friday. Where 4,000 clinics normally offer yellow fever vaccinations, merely 252 in the country will have vaccine while the shortage persists. People who contract yellow fever can experience fever, headache, backache, muscle pains, loss of appetite, and nausea or vomiting. Only four manufacturers in the world make yellow fever vaccine, and only one product — made by Sanofi Pasteur — is licensed in the US. The challenge for the US supply relates to problems faced by the only manufacturer that sells yellow fever vaccine in this market, Sanofi Pasteur.
