- South Africa’s solely snake antivenom producer can’t make sufficient of its polyvalent antivenom, which treats bites of not less than ten venomous snakes.
- Experts are fearful that dwindling shares are going to trigger a much bigger drawback within the coming months, with many veterinarians now working out of antivenom.
- Johan Marais, CEO of the African Snakebite Institute, says it’s a “major disaster” that medical doctors and vets can’t pay money for the polyvalent antivenom.
Snake specialists are elevating the alarm over a shortage of South African-produced polyvalent snake antivenom, as a manufacturing backlog is inflicting ready occasions of not less than six months for the supply of the life-saving snakebite therapy.Stocks of snake antivenom are dangerously low
Venomous snakes
The polyvalent antivenom is the gold customary for the therapy of venomous snake bites and is produced in Johannesburg by the South African Vaccine Producers (SAVP), a subsidiary of the National Health Laboratory Service (NHLS). This antivenom (SAIMR Polyvalent Snakebite Antiserum SAVP) treats snakebites from the Black Mamba, Green Mamba, Jameson’s Mamba, Cape Cobra, Forest Cobra, Snouted Cobra, Mozambique Spitting Cobra, Rinkhals, Puff Adder and Gaboon Viper.
In the previous couple of months, an enormous manufacturing backlog on the SAVP has led to shortages at well being services, particularly amongst veterinarians, based on Johan Marais, herpetologist and CEO of the African Snakebite Institute.

“People’s dogs have died because for the last eight months veterinarians cannot buy antivenom. It really is a big problem,” stated Marais.
He stated he not too long ago spoke to a medical physician who couldn’t get his fingers on antivenom.
Around 3,500 persons are bitten by snakes in South Africa annually, with 800 hospitalisations, Marais estimated. Of these, solely about 10% require antivenom therapy, and relying on the snakebite, therapies vary from six to twenty vials per affected person.
Marais estimates that there are 10 snakebite deaths per year in South Africa. The most up-to-date cause of death data from Statistics South Africa discovered that there have been 47 deaths from “contact with venomous animals and plants” in 2018.
Marais stated that bites from Puff Adders and Mozambique Spitting Cobras have to be handled rapidly as they will trigger extreme tissue harm. If left untreated for too lengthy, the affected person may have a number of operations to restore the harm. He stated the shortage has worsened within the final eight months. Marais stated this has beforehand been an issue, however not fairly as dangerous as the present state of affairs.
Antivenom manufacturing
Another problem was that South Africa’s polyvalent antivenom is purchased and utilized in different African international locations, resembling Kenya and Senegal. Kenya at present doesn’t manufacture its personal antivenom and experiences about 700 snakebite deaths per year, many greater than South Africa.
Mike Perry, founding father of African Reptiles and Venom, provides the SAVP with the uncooked snake venom used to provide the polyvalent antivenom. Perry stated it takes just a few months to provide the antivenom; however the venom he provides in 2023 will solely be a part of the antivenom out there in 5 years.
Perry defined that the snake venom he provides to the SAVP is injected into horses in low doses over lengthy durations of time. When the horses grow to be hyperimmune to the venom, blood is drawn from the horses and the antibodies in opposition to the venom are separated from the blood.
NHLS spokesperson Mzimasi Gcukumana informed GroundUp that the SAVP is “working around the clock” to scale back and in the end eradicate the backlog of antivenom manufacturing.
Gcukumana stated loadshedding has negatively affected antivenom manufacturing. He stated the laboratory was in a position to provide “some provincial health departments and some private facilities, including 13 veterinary practices, during December to ensure there is adequate supply in the country”.
The laboratory stated it plans to strategically place antivenom banks in high-risk areas throughout the nation.

The National Department of Health spokesperson Foster Mohale stated that it at present doesn’t have a contract with the producer for antivenom regardless of it being “an essential medicine”.
Mohale stated the SAVP knowledgeable officers that the “difficulty in sourcing the material” was the rationale for the present low inventory. Mohale didn’t have statistics as every province typically buys antivenom straight from the SAVP.
