Biosearch Life assesses connection between COVID-19 vaccination, diet and immunity

02 Sep 2021 --- As COVID-19 vaccinations roll out globally, Biosearch Life is highlighting the role that diet can have on efficacy. Ahead of the Spain-based biotechnology company’s webinar, NutritionInsight speaks with two experts about the interplay between nutrition and vaccines, as well as the lasting impact the pandemic will have on industry.

“Diet, immunity and vaccines are closely related. The effectiveness of a vaccine depends on the immune status of the person,” explains Mónica Olivares, R&D director at Biosearch Life. 

This is why, for example, the effectiveness of vaccines is lower in elderly people who show some dysfunction of the immune response than in young individuals.

The impact of diet on the immune system is well-known and is therefore a key factor for the optimal functioning of the immune system, Olivares continues. 

“In this context, the bacteria that are part of our diet, either in fermented foods or as probiotic supplements, play a very relevant role. We could say that they act as ‘trainers’ for the cells of the immune system, preparing them to act at their maximum capacity in case of infections.”Innova Market Insights reports that many products feature both probiotic and immune health claims.

Probiotics modulate immune system
According to Innova Market Insights, over three-quarters of consumers say that probiotics are at least somewhat important for immunity, with 67 percent saying the same about prebiotics. 

“Increasing evidence shows that particular strains of probiotics play a role in modulating the immune system,” explains Olivares.

In addition, particular strains of probiotics may help to support the immune system by promoting the production of natural antibodies in the body and supporting the growth of beneficial gut bacteria.

Last month, A&B Ingredients also detailed the role of probiotics in modulating immune response and the effects of COVID-19. 

Meanwhile, both AB-Biotics and Danone have backed studies investigating the link between COVID-19 and probiotics. 

Embracing holistic approaches
Vaccinations are key to reducing the severity of COVID-19 cases. Another trend within immunity is a holistic and preventative approach. This could include choosing foods naturally rich in nutrients, such as vitamins, minerals and probiotics, explains Beatriz Botija, product manager of probiotics at Biosearch Life.

“Numerous market studies show that immunity has become a priority for many consumers around the world. They are looking to take a more preventative approach to health and improve immune health in order to face future infections.”

She continues that this increased awareness of immunity has also led to an increased awareness of nutrition and how improving the diet can support immune health.

“As the World Health Organization’s dietary guidelines state, good nutrition is crucial to health, especially at times when the immune system might need to fight back.”

Eyeing the future
Immunity was top-of-mind throughout 2020 and 2021 and will continue to be in the future, predicts Botija.

“Since immunity concerns are here to stay, many people will be looking for proven immune health support solutions that do not interfere with their daily routine. Some of the solutions could be fortified foods or beverages and dietary supplements.”

Olivares adds that other long-term impacts of COVID-19 are difficult to estimate.

“The fact that those vaccinated can become infected and contagious, as well as its ability to mutate, complicates the resolution of the pandemic and suggests that this new virus will coexist with us just as other viruses such as influenza do. Vaccines will be key to reducing the severity of cases and the virus’s ability to spread,” she states. 

On September 7, a Biosearch Life webinar will expand on how probiotics may help reduce the incidence of infections and reduce severity. Registration is currently open here.
