There are several types of modified vaccines, each with its unique approach to improving vaccine efficacy:
Recombinant Vaccines: These vaccines use a piece of the pathogen's DNA to stimulate an immune response without using the whole organism. Conjugate Vaccines: These vaccines combine a weak antigen with a strong antigen to elicit a stronger immune response. Vector Vaccines: These vaccines use a virus or bacterium to deliver the genetic material from the pathogen to the host cells, triggering an immune response. mRNA Vaccines: These vaccines use messenger RNA to instruct cells to produce a protein that triggers an immune response.
