The South African National Health Laboratory Service (NHLS) has stopped manufacturing snake, scorpion, and spider antivenom, with no clear timeline for resumption, placing millions across sub-Saharan Africa at risk.
The NHLS has confirmed that all antivenom production ceased due to construction work, leaving stockpiles empty—except for boomslang antivenom.
This crisis is particularly alarming as South Africa records approximately 4,000 snakebites annually, with around 900 hospitalisations and 100 patients requiring antivenom. The country also sees 15 snakebite-related deaths per year.
Manufacturing Halted Due to Infrastructure Upgrades
The NHLS states that extensive upgrades at the South African Vaccine Producers (SAVP) facility led to the suspension of antivenom production. The infrastructure, already ageing, struggled to comply with Good Manufacturing Practices (GMP), and frequent load shedding exacerbated operational disruptions. The Service is now focused on cleaning, validation, and quality control to meet regulatory standards before resuming production. “We are doing everything possible to speed up the process and will provide updates,” Gcukumana assured.
Imported Antivenom Inaccessible for Most Patients
With Easter approaching—a peak snakebite season—the situation is dire. Several sub-Saharan countries, including Uganda, previously sourced antivenom from South Africa but must now look elsewhere.
South Africa is importing an alternative from India, but this presents challenges.
According to Arno Naude of Snake Bite Assist: “It’s cheaper but requires higher doses. Worse, it’s unavailable in state hospitals and isn’t registered for use on South African snakebites, meaning doctors refuse to administer it.”
Meanwhile, a more effective alternative is used successfully in Eswatini, with zero deaths recorded in 800 cases—but it remains unapproved for human use in South Africa.
“Poor and rural people will be hit hardest,” Naude stressed. “Most state hospitals have enough for maybe two or three bites—after that, they’re out.”
The crisis extends beyond snakebites.
The NHLS no longer has antivenom for scorpion stings or spider bites. A child in Botswana recently died from a scorpion sting after their family sold everything to afford antivenom—
only to find it was ineffective against local species.
Naude warns that deaths could reach the hundreds or thousands, especially in the Northern Western Cape, Northern Cape, Limpopo, Botswana, and Namibia, where deadly thicktail scorpions are common.
Calls for Urgent Government Action
The Democratic Alliance announced that the NHLS will be questioned in Parliament on 5 March about the crisis.
In a press statement issued on its website, the DA stated: “We will demand clarity on how much anti-venom has been produced and distributed since 2023. The NHLS must also account for reported shortages in hospitals and what is being done to address them.”
Even if the NHLS resumes production immediately, experts warn that it could take months before new antivenom reaches hospitals.
“We have a huge crisis on our hands,” Naude emphasised. “And this country should be held responsible for deaths across sub-Saharan Africa because of what the NHLS has done.”
