Holidaymakers may be at risk of contracting a deadly infection that could make their eyes bleed due to an extreme shortage of the vaccine that protects against it.
The yellow fever jab is predicted to be unavailable for the next two to three weeks, according to a report published by the Foreign Office.
Yellow fever is a serious and life-threatening infection predominately spread by mosquitos in certain parts of Africa, South and Central America and the Caribbean.
Whilst most people who contract the viral infection experience mild flu-like symptoms before making a full recovery, in some cases it can be fatal.
Patients who develop a severe illness with fever, jaundice—yellowing of the eyes and skin—dark urine, stomach pain and bleeding for from the eyes, nose, mouth or stomach are at significant risk of death, the NHS warns.
The National Travel Health Network and Centre (NaTHNaC), a UK based organisation that works closely with the Foreign Office, recommends anyone travelling to these countries to get vaccinated against the infection.
However, Sanofi, the manufactures of the yellow fever vaccine have now warned that it could be out of stock for up to three weeks, putting travellers at serious risk.
The yellow fever vaccine—which costs around £70—is offered to anyone over the age of nine months who is travelling to a high-risk area, or a country that requires certification of vaccination.
Current guidelines advise travellers to get vaccinated at least 10 days before travel, to allow enough time for the vaccine to work.
For most people, the vaccine should provide lifelong protection against yellow fever, but a further dose is recommended to travellers who are at a higher risk of illness.
This includes anyone who was vaccinated under the age of two, pregnant women, and those living with HIV.
Whilst some countries require proof of vaccination—which is thought to be a highly effective method of preventing the spread of infection—for some destinations, it is simply recommended.
Health officials have urged travellers to contact their local vaccination center who should be able to advise whether vaccination is appropriate.
Where vaccines are unavailable, health professionals are advised to contact the NaTHNac to discuss available options.
The NHS says it is also vital to prevent mosquito bites—through using insect repellent and wearing protective clothing— as this can ward off the bugs carrying the infection, as well as other serious diseases.
The most recent reported case of yellow fever in the UK was in 2018, after a traveller returned from Brazil.
Prior to this only 11 cases were reported in travellers from Europe and the United States who visited high risk area between 1970 and 2015, according to official figures.
However between 2016 and 2018 there was a sharp rise in travel associated cases of the infection—most likely linked to outbreaks in Brazil.
While the virus cannot spread person to person, if you are infected, a mosquito can bite you and then infect someone else.
According to the World Health Organisation (WHO), 777 cases of yellow fever were reported across eight Brazilian states during this time, tragically killing 261 people.
An estimated 200,000 cases of yellow fever are reported worldwide each year, including 30,000 deaths.
Whilst vaccination is thought to be the best method to prevent against infection—with more than 600million doses of the vaccine administered worldwide—the yellow fever vaccine can cause serious side-effects.
After having the vaccine, up to a third of people experience headache, muscle pain and a high temperature.
These side-effects usually pass within a couple of weeks but in very rare cases the vaccine can cause life-threatening organ damage.
