A vaccine is a biological preparation that contains an agent that resembles a disease-causing microorganism and is made from weakened and killed forms of microorganisms. Vaccines can be categorized into many types such as inactivated vaccines, attenuated vaccines, toxoid and conjugate. Cholera, influenza, hepatitis A, polio and rabies vaccines are inactivated vaccines. The global vaccines market is categorized on the basis of different diseases to be treated. Various diseases that are treated using H1N1 vaccines include influenza, meningococcal, cervical cancer, pneumococcal, hepatitis, measles, mumps, rubella and others. H1N1 vaccines refer to the medical preparation for treatment of swine flu. H1N1 influenza is an infectious disease whose causative agent is a variant of the swine H1N1 virus. H1N1 virus is an RNA virus belonging to the orthomyxoviridae family and infects nose lungs and throat. In addition to humans, this virus may infect different animal species such as birds, swine, horses and others. On the basis of its surface composition, H1N1 virus can be classified into neuraminidase and hemagglutinin. Hemagglutinin is used by the virus to bind to host cell receptors and allow the entry of virus into the host cell. H1N1 vaccines market is growing at a significant rate due to rise in elderly population which is prone to such infectious diseases. In addition, rise in prevalence of chronic diseases such as lung disease, asthma, neurological disorders and others.
