Here I breakdown the general components found within vaccines, with an extra focus on the mRNA vaccines for SARS-CoV-2. This is part two collaborating with Dr. Sabrina Solouki , and if you missed her video on what an allergic response is check it out on my YouTube page.

While preservatives and adjuvants are safe and common vaccine components, both the Pfizer and Moderna vaccines are preservative and adjuvant free. Both vaccines also require cold temperatures for storage purposes to ensure the mRNA within the vaccine stays intact. Therefore, while a cold temperature is necessary for storing the vaccine, this does not mean that vaccines kept outside the temperature range are unsafe—rather, such vaccines simply lose efficacy.

I do use some technical terms, please find them defined below. As always, thank you for taking the time to learn more about the mRNA vaccines & we are happy to hear any questions!

(technical terms: PEG [polyethylene glycol] = a synthetic substance that is water soluble; aiding in delivery for vaccines. pH = scale used to specify the acidity or basicity of a solution; typical body pH is 7.4.)
