Compared to other types of vaccines, mRNA vaccines have a number of unique benefits, and our company is fully dedicated to delivering high quality mRNA vaccine development services. When engaged in partnership with us, you acquire access to outstanding platforms that are perfect to boost your vaccine research and commercialization efforts.
Introduction to mRNA Vaccines
mRNA vaccines make use of messenger RNA (mRNA) in order to induce the immune response. Unlike the typical vaccines which rely on either a weakened or inactivated strain of the pathogen, mRNA vaccines make use of a small piece of mRNA that codes for a protein from a virus. This mRNA is introduced into the body, guiding cells to produce the viral protein and prompting an immune response.

How Do mRNA Vaccines Work?
mRNA vaccines have a sequenced several steps which detail their primary modes of action.
| Step |
Description |
| Cellular Uptake and Protein Production |
Cells internalize mRNA molecules post vaccination. Such cellular processes acknowledge the mRNA that was introduced and instigate the translation of such mRNA into viral proteins. |
| Antigen Presentation |
A newly synthesized viral protein is expressed on the cell surface, eliciting the immune system's response to non-self proteins present in the pathogen. |
| Immune Response Activation |
In foreign proteins an immune response is triggered, also stimulation of B and T cell takes place. T cells consolidate and amplify the immune response. Antibodies in response to the viral proteins are synthesized by B cells. |
| Memory Cell Formation |
In addition to providing cellular immunity, mRNA vaccination induces the production of memory B and T cells as well which have a record of the viral protein and therefore allows for an effective and rapid response to future exposures to the viral agent. |
Application of mRNA Vaccines in Infectious Disease Prevention
The preventive measures against infectious illnesses have been greatly boosted with the introduction of mRNA vaccines. Their distinct feature and mode of function allows them to be the promising candidates in the fight against various pathogens. Several approved mRNA vaccines are listed below.
Pfizer-BioNTech vaccine
The Pfizer-BioNTech vaccine is an approved and typical mRNA vaccine. This vaccine utilizes messenger RNA (mRNA) to encode the spike protein found on the surface of the SARS-CoV-2 virus. After administration, the mRNA instructs cells to produce the spike protein, triggering an immune response to prevent COVID-19.
Moderna vaccine
The COVID-19 vaccine that was developed by Moderna, Inc has been classified as typical mRNA vaccine. Like the Pfizer-BioNTech, this vaccine also employs the use of mRNA to code for the SARS-CoV-2 virus's spike protein allowing the host to mount an immune response against the virus.
