US Pauses Chikungunya Vaccine Over Severe Side Effects

US health authorities have suspended the license for the Ixchiq vaccine against the chikungunya virus following reports of “serious adverse events”, the drug’s French maker said Monday.

Ixchiq is one of just two vaccines approved by the US Food and Drug Administration for the mosquito-spread virus, which mainly occurs in tropical and subtropical regions but has recently been discovered to countries worldwide.

French company Valneva obtained US approval for the vaccine in 2023, but reports of side effects have prompted reviews in particular over its use in older patients, including by the European Medicines Agency this year.

“The suspension of the license is effective immediately,” Valneva said of the FDA order issued Friday, citing four additional cases of serious side effects, three of which involved people aged 70 to 82.

“As we determine potential next steps, and as the clear threat of chikungunya continues to escalate globally, Valneva remains fully committed to maintaining access to our vaccine as a global health tool,” chief executive Thomas Lingelbach said in a statement.

Public health experts say chikungunya could be a potential future pandemic threat as climate change pushes the mosquitoes that spread it into new regions.

The symptoms are similar to those of dengue fever and Zika virus, with high fever and severe joint pain that is often debilitating and varies in duration.

Chikungunya is rarely fatal, though there is an increased risk of death for babies and the elderly.

In July, the World Health Organization warned of the risks of a major chikungunya epidemic, calling for urgent action.

The agency said it was picking up the same early warning signs as in a major outbreak two decades ago, which swept across the Indian Ocean before spreading globally and affecting almost half a million people.

So far this year, Europe has seen 27 chikungunya outbreaks, a new record for the continent, the European Centre for Disease Prevention and Control said this month.

The Nigeria Centre for Disease Control and Prevention (NCDC) has confirmed that Lassa fever has claimed 259 lives and infected 1,086 people across 24 states and 118 local government areas so far in 2026.

In its latest Lassa Fever Situation Report for epidemiological week 36 (August 31 to September 6), the agency said the figures represent a case fatality rate of 23.9 percent — significantly higher than the 18.6 percent recorded during the same period in 2025.

Twelve new confirmed cases were recorded in week 36, a decline from the 18 cases reported the previous week. The fresh infections were detected in Ondo, Edo and Kogi states.

Five states continue to bear the heaviest burden, accounting for 87 percent of all confirmed cases this year: Bauchi, Ondo, Taraba, Benue and Edo. People aged 21 to 30 remain the most affected age group.

The NCDC noted that no new infections among healthcare workers were recorded during the latest reporting week. The agency continues to urge the public to maintain hygiene, avoid contact with rodents and their droppings, and seek early medical care if symptoms appear.

• A surgeon performing tele-robotic surgery.

Nisa Premier Hospital, Abuja, has partnered with RoboMed Global and The Redeemer’s Health Village (RHV) to successfully perform what the hospital described as the first tele-robotic surgery in Nigeria and West Africa.

The landmark kidney cancer surgery was performed on a patient at Nisa Premier Hospital, Abuja, while the surgeon, Professor Obi Ekwenna-Davis, remotely controlled the robotic surgical platform from Redeemer’s Health Village in Lagos.

The procedure, which lasted approximately three hours, was performed to remove a kidney affected by a cancerous tumour.

The hospital said the patient had been discharged following the successful procedure, although details about the patient’s identity and condition were withheld for privacy reasons.

Speaking during an event to mark the milestone, the Chief Executive Officer of Nisa Premier Hospital, Dr Ibrahim Wada, said the development demonstrated the potential of tele-robotic surgery to connect specialist surgical expertise with patients across Nigeria.

Wada said the procedure was carried out using the MicroPort robotic surgical platform installed at Nisa Premier Hospital, with the remote surgeon controlling the system from Lagos.

He said the development could reduce the need for Nigerians to travel abroad for specialised medical treatment, thereby reducing expenditure on international travel, accommodation and medical services.

According to him, the technology also creates an opportunity for Nigerians to access specialised expertise from doctors located in other parts of the world without requiring the doctors to travel physically to Nigeria.
