The World Health Organization says the first-ever vaccine for dengue needs to be dealt with in “a much safer way,” meaning that the shot should mostly be given to people who have previously been infected with the disease.

In November, the vaccine’s manufacturer, Sanofi Pasteur, said people who had never been sickened by dengue before were at risk of developing a more serious disease after getting the shot.


After a two-day meeting this week, WHO’s independent vaccines group said it now had proof the vaccine should only be used “exclusively or almost exclusively in people who have already been infected with dengue.”

The U.N. health agency said a test should be developed so doctors would be able to quickly tell if people had previously been sickened by dengue – but the group acknowledged doing that so isn’t straightforward.

“We see significant obstacles in using the vaccine this way, but we are confident this also spurs the development of a rapid diagnostic test,” said Dr. Joachim Hombach, executive secretary of WHO’s expert group, during a news conference Thursday.

Sanofi said last year that doctors should consider whether people might have been previously infected with dengue before deciding whether they should risk getting immunized. The company said it expected to take a 100 million euro ($118 million) loss based on that news.

People who catch dengue more than once can be at risk of a hemorrhagic version of the disease. The mosquito-spread virus is found in tropical and sub-tropical climates across Latin and South America, Asia, Africa and elsewhere. It causes a flu-like disease that can cause joint pain, nausea, vomiting and a rash. In severe cases, dengue can result in breathing problems, hemorrhaging and organ failure.

About half the world’s population is at risk of dengue; WHO estimates that about 96 million people are sickened by the viral infection every year.

Following Sanofi’s announcement last year, the Philippines halted its dengue immunization program, the world’s first national vaccination program for dengue. The government also demanded a refund of more than 3 billion pesos ($59 million) from Sanofi and is considering further legal action.

In February, the Philippines said the vaccine was potentially linked to the deaths of three people: all of them died of dengue despite having received the vaccine.

The country imposed a symbolic fine of $2,000 on Sanofi and suspended the vaccine’s approval, charging that the drugmaker broke rules on how the shot was registered and marketed.

More than 730,000 children aged 9 and above in the Philippines have received at least one dose of the dengue vaccine, usually delivered in three doses.

Afghans were by far the largest group of applicants in the EU in September.

Afghans lodged more than 17,000 asylum applications in the EU in September, up from 10,000 in August and nearly twice as many as Syrians. This made Afghanistan by far the main country of origin, which Syria had been for seven years until July, the European Asylum Support Office (EASO) said.


Total applications in the EU exceeded pre-pandemic levels for the first time since the outbreak of Covid-19.

Aviation has revolutionised tourism and business forever, not to mention the cultural linkages that have been made possible.

International Civil Aviation Day is observed on December 7th to recognize the flying industry’s impact on modern society. In 1994, as part of ICAO’s (International Civil Aviation Organization) 50th-anniversary celebrations, the first International Civil Aviation Day was observed, and in 1996, the United Nations General Assembly declared December 7th as International Civil Aviation Day.

Incomplete data entries and loopholes in the ledger are significant factors in slowing down the accounting process.

By- Harris Scott

Business owners hardly have time to look into all aspects of a business operation, and accounting is one aspect. While small business owners might invest some time handling accounting services, it is indeed a big waste for owners of major enterprises. Regardless of the size of the business, your organization needs someone to look after the ledger.
