Alarm sounded on shortage of livestock vaccines in South Africa

On the Covid-19 front, South Africa has too many vaccines and not enough people willing to take the jab or able to access an injection. But vaccine challenges in the country are not confined to Homo sapiens. 

According to farmers, vets and executives in the agriculture sector, there have been critical and persistent shortages of vaccines needed to protect livestock — horses, cattle and sheep — from a range of infectious vector-borne diseases. This comes against the backdrop of an extremely wet summer season that has created a flourishing environment for dangerous parasites.

The diseases include blue tongue, African Horse sickness and Rift Valley fever. 

The Onderstepoort Biological Products (OBP) board admits there have been production issues which it attributes to past failures to maintain the plant properly as well as ongoing woes such as load shedding — a bane to all South African industries. 

In an interview with Business Maverick at the OBP facilities in Pretoria, chairperson Rene Kenosi said there had been numerous production challenges. 

“I am not painting a rosy picture, because it is not rosy,” said Kenosi in her characteristically blunt manner. 

“When we were appointed on 1 November 2020, we were greeted with a strike. We had HR-related problems. We had production which was not happening at that point due to infrastructure breakdowns. We did not produce until February 2021.”

Even then, production remained intermittent until May 2021.

“If you are sitting with an organisation with aged infrastructure, you are not going to wake up and wave a magic wand and have new infrastructure. We are going through a process of maintaining, augmenting and procuring equipment which is planned over the short, medium and long term. Equipment was not maintained in the past,” she said. 

There are echoes of Eskom here. 

Kenosi said that an infrastructure plan had been presented to Agriculture Minister Thoko Didiza to address these issues. The costs have not yet been made public, but they will be considerable.

Herd’s immunity in question

Several vets and farmers who spoke to Business Maverick said there have been periodic shortages of crucial livestock vaccines coming out of OBP for several years. 

The problem seems to have taken a turn for the worse in recent months, at a time when South Africa’s agricultural sector is one of the few green shoots amid a desolate economic landscape.

But OBP’s acting CEO, Luvuyo Mabombo, told Business Maverick “the vaccines that the market requires right now are available… they are in the supply chain”.

“The equine industry is currently vaccinating,” he said by way of example. 

Sources in the equine industry confirmed to Business Maverick this was indeed the case. However, there were vaccine shortages during the peak season for African Horse sickness, an often fatal disease spread by infected insects that affect horses, donkeys and mules. 

“There is no shortage at the moment, but there was last year between June and 31 October when it was African Horse sickness season. We could not get enough vaccines from Onderstepoort, and they know exactly how many horses should be injected, so we do not understand why there was a shortage,” said one large animal hospital, which asked not to be named, in response to queries. 

Another large animal hospital also said there were shortages last year which may have been attributable to the production problems earlier in 2021.

“There have been important vaccines either unavailable or in short supply at critical times. These include vaccines for the insect-transmitted viral diseases blue tongue, African Horse sickness, lumpy skin disease and Rift Valley fever. There have also been shortages of the blood vaccines for the tick-borne diseases heartwater, redwater and gallsickness,” Dr Leon de Bruyn, president of the South African Veterinary Association, told Business Maverick. 

He also said there was a shortage of the Brucella Strain 19 vaccine. Brucellosis is a bacterial zoonosis that causes Malta fever in humans from drinking infected milk or coming into contact with animal tissue containing brucella bacteria.

“I would stress that we are adopting a constructive approach to support and assist the state with disease control. This is not a case of criticism by throwing stones from the outside. We want to collaborate and help,” he said.  

Concerned industry executives, vets and scientists have written and signed an open letter — published by Business Maverick — raising the alarm about the situation. 

It states that the consequences of ongoing livestock vaccine shortages “could be dire”, noting that:

• Good rains have fallen in SA in the 2021/2022 season, creating conditions where parasites transmitting animal diseases generally thrive;


• Many animals that should have been vaccinated to prevent diseases transmitted by these parasites remain unvaccinated;


• The cattle, sheep and horse industries could face a very bleak 2022.
