Different vaccine types

In a very short Medium article today I go into the different types of vaccines that are on offer currently, with helpful information which can be understood easily. Hope you enjoy the article.

➡ Types of vaccines
Synthetic vaccines — chemically synthesized peptides, they can be made to order for any wanted sequence, however, there may be few in use today

Recombinant vaccines — these are produced by genetic engineering, through recombinant DNA technology.

Subunit vaccines — these types of vaccines consists of only some components of the virus, sufficient enough to induce a protective immune response, but not enough to allow the danger of infection.

Toxoid vaccines — these types of vaccines use a toxin made by the germ that causes a disease. They create immunity to the parts of the germ that cause disease instead of the germ itself.

Virus vector vaccines — these have been genetically manipulated to express protective antigens from relatively unrelated disease-causing viruses, the idea is to utilise the genome of a well-understood attenuated virus to express and present antigens to the immune system

Inactivated vaccines — these vaccines are produced by exposing the virus to a denaturing agent under precisely controlled conditions, the main objective is to cause loss of virus infectivity without loss of antigenicity, the virus used in production is a killed virus.

Live (attenuated) Virus vaccines — use of a weakened live virus with reduction of causing the disease to the vaccine host in order to stimulate an immune response

mRNA vaccines — an mRNA vaccine uses a copy of a molecule called messenger RNA to produce an immune response

Well, there we have it, the different types of vaccines that we have in circulation from the past and today as well.
