Immune Response Declines with Ageing. You can Fight Back.

When it comes to immune response when vaccinating, your age matters. That's why it's important to know what vitamins and minerals have been linked to vaccine response and effectiveness in order to avoid their deficiencies when getting a shot.

Curbing a pandemic is no small feat, and doing it with a weakened immune responses is even harder. Unfortunately, as we age our immune system weakens. This is called immunosenesence. Ageing is inevitable, but micronutrient deficiencies aren't.


The immune system requires many micronutrients to function properly and protect us against diseases. Vitamins and minerals deficiencies, often resulting from poor diets, can contribute to weakened immune system especially in the elderly. A weakened immune system is often correlated with vitamin and mineral deficiencies.


Micronutrients Matter

All micronutrients are important, but when it comes to immune response when vaccinating, some have more evidence in their corner than others. Research has shown that vitamins A, B, C and D and the minerals zinc, selenium, iron and copper are all needed for the immune system to function properly. Additional research has shown that Quercetin, a potent flavonoid, probiotics and essential amino acids also play key supporting roles toward maintaining a healthy immune system.


A weakened immune system can lead to poor vaccine responses. A review of studies including 2,367 patients showed that vitamin D deficiencies resulted in lower protection rates against certain flu strains compared to individuals with healthy levels of vitamin D.


Randomized controlled trials of vitamin and mineral supplements in older populations have been shown improved immune response to viral challenges. While most people are familiar with the benefits of Zinc and Vitamins A, C and D, a recent study with Selenium has shown better cure rates for COVID-19.


Maintaining a healthy immune system is always better and trials have confirmed this to be true, particularly in older people. Responses to vaccination improve with improved nutrition and lifestyle. A healthier diet and immune system may help produce more antibodies and protect against new diseases following vaccinations.


The right supplements at the right time

While all micronutrients matter, some are harder to come by than others. Certain micronutrient deficiencies are geographically or demographically driven. For example, westerners over 60 were found to be consistently deficient in selenium, zinc, iodine and copper. This is an issue that disproportionately affects the elderly, but not exclusively. Poor nutrition is found across all ages and geographies. The most common micronutrient deficiencies include vitamins A, B12, C and D as well as minerals zinc, selenium and copper.


Avoiding the most common micronutrient deficiencies was the guiding principle behind the development of VACCI PREP. It's unique formulation specifically targets micronutrients with abundant clinical evidence to immune response following vaccinations.



Certain micronutrient deficiencies may limit the effectiveness of vaccines, especially as we age. But, you don't have to take it sitting down. You can help yourself by leading a healthy lifestyle (read "Your Vaccine Preparedness Checklist") and supplementing your nutrition with VACCIPREP before and after vaccinations.


You got this!
