A vaccine is a biological preparation made to immunize the body to prevent causing disease. Even if the host develops antibodies, the human immune system is not perfect and in any case the immune system might still not be able to defeat the infection immediately. In this case, the infection will be less severe and heal faster. There are several types of vaccines in use. These represent different strategies used to try to reduce risk of illness, while retaining the ability to induce a beneficial immune response. Different types of vaccines are: Killed, Attenuated , Toxoid; Subunit ;Conjugate ;Valence and Heterotypic. The immune system recognizes vaccine agents as foreign, destroys them, and ""remembers"" them. When the virulent version of an agent is encountered, the body recognizes the protein coat on the virus, and thus is prepared to respond, by neutralizing the target agent before it can enter cells, and recognizing and destroying infected cells before that agent can multiply to vast numbers.
Open Access should be seen as a means of accelerating scientific discovery by providing free and unrestricted access of scientific knowledge via the Internet. An essential role of Open Access is the long-term preservation of peer-reviewed scholarly journal articles and research data. An Open Access publishing group focuses on to encourage innovation, socio-economic development, and flow of knowledge around the world. One such, Open Access is OMICS which is committed ultimately for public welfare to stimulate the growth of global science, as well as maintain the quality of scientific achievements at the same time. articles on vaccines are published in journal of bioterrorism and biodefense, this journal publishes quality manuscripts which has good impact on the society.
