What are the types of adjuvants?
2. Classification of Adjuvants

|---|---|
| Immune potentiators | Muramyl dipeptide (MDP) |
| Saponins (QS-21) | |

What is Freund’s complete adjuvant?
Complete Freund’s Adjuvant (CFA) consists of heat-killed Mycobacterium tuberculosis in non-metabolizable oils (paraffin oil and mannide monooleate). CFA contains trehalose 6,6′ dimycolate (TDM), which stimulates Mincle. CFA can be used to produce water-in-oil emulsions of antigens.
Which one is used as adjuvant?
Aluminum, one of the most commonly used adjuvants, was first discovered to have adjuvant properties back in 1926. Since then numerous vaccines, such as hepatitis A, hepatitis B, diphtheria-tetanus, Haemophilus influenza type b, and pneumococcal vaccines have been developed with the use of aluminum adjuvants.
Does Pfizer vaccine have adjuvant?
The authorised mRNA vaccines against COVID – made by Pfizer and Moderna – also contain an adjuvant. Messenger RNA (mRNA) is a set of genetic instructions for our cells to make the spike protein, which is found on the surface of the coronavirus.
What are the two types of adjuvants?
Based on their mechanism of action, adjuvants have been categorised into two broad groups; the particulate vaccine-delivery systems that target antigen to antigen presenting cells (APCs) and the immunostimulatory adjuvants that directly activate such cells through specific receptors e.g. toll-like receptors (TLRs) …
What are adjuvants Name any two adjuvants?
What is freunds incomplete adjuvant?

What is alum adjuvant?
Alum, the classical adjuvant most often used in vaccines in humans, includes a range of salts of aluminum precipitated under basic conditions, usually aluminum sulfate mixed with sodium or potassium hydroxide plus a variable amount of phosphate.
