How to achieve herd immunity in the building and construction sector

There are a lot of myths around vaccines as a whole, but there seems to be even more hesitancy around COVID-19 vaccinations, even in South Africa’s building and construction sector. However, achieving herd immunity in this sector is integral and there are some practical and innovative ways to make the vaccine for accepted and accessible.  

“We all know what we need to do. The message is simple: Get vaccinated,” says Phumelele Makatini, chief executive and principal officer of The Building and Construction Industry Medical Aid Fund (BCIMA). 

Makatini, the host of Tea with Phumi, a conversation platform which aims to provide further insights into developments within the South African healthcare and medical scheme’s environment, recently discussed innovative ways to ensure that vaccinations are brought within reach of the people with epidemiologist and vaccinologist Professor Charles Shey Wiysonge on the second episode of her online show. 

Barriers to COVID-19 vaccinations 

“There are a lot of myths around vaccines as a whole, but I think there is more hesitancy around COVID-19 vaccinations than vaccinations in general,” said Professor Wiysonge.  

“During the COVID-19 pandemic, we have heard more about vaccinations in the public domain than at any time before. The barriers to COVID-19 vaccinations uptake range from supply and availability to the psychosocial factors that inhibit the uptake. Even in one country, we might find that there is more of a certain challenge in one region than in the rest of the country. Challenges cover a wide range and may also vary as time goes on. We may find that when the challenges of availability and access are solved, we are confronted by psychosocial factors.” 

According to Professor Wiysonge, we have a long way to go, but we also need to celebrate what we have achieved. “In the beginning we had quite a problem with access, supply and availability. Now we have a steady supply and more vaccination sites have been opened. Now people from the community need to come,” he says.

No one size fits all solution 

He told Makatini that there is a different solution to each barrier, as there is no one size fits all solution. For example, when South Africa had supply and availability problems, it was up to our government to negotiate and sign contracts with vaccine manufacturers directly, to obtain vaccines through the African Union, or to obtain them through the Covax facility.  

In terms of access, there are parts of the country where people may have to travel long distances to come to vaccination sites, which can for many be prohibitive. Vaccination therefore needs to be brought to the people. Having many vaccination sites close to where the people are situated is vital.

Innovative thinking 

Professor Wiysonge believes the most immediate solution to barriers is innovative thinking. “This includes vaccinations in places such as taxi ranks, or grant queues for the aged. I think the government and the private sector are doing a lot to bring vaccinations to the people, but we need to do more to ensure that people don’t have to travel long distances to get their jabs. We also need to have more vaccination stations open on weekends.” 

Prof Wiysonge says we also need to consider more convenient hours and look into the possibility of vaccination options such as trains or long-distance busses.  

He agrees that vaccine hesitancy is a real problem. But we need to understand the hesitancy, listen very carefully to what the concerns are and provide adequate responses in the form of solutions and accurate information.  

Repercussions of failing to vaccinate will be severe 

The repercussions of failing to overcome vaccination barriers are severe, says Professor Wiysonge. On the individual level, vaccinations protect the vaccinated person, but if we can vaccinate sufficient numbers, we can stop the transmission of infections. This is what we refer to as herd immunity.  

“For that we need to have a very high vaccination percentage. At first, we used to talk about 67%, but of course knowing that not everybody in the country is eligible for vaccination, we need very, very high coverage in the adult population – maybe 90%, even 95%. In that way we may reduce or even stop the transmissions. There would be protection at the individual level, but also at community level. 

“For this to happen, people need to have the right information and we all have to play our part to make sure that people are literate about vaccinations,” Prof Wiysonge concludes.
