Advancements in Vaccines and Therapeutics

Vaccines are the products that can produce immunity from a disease and can be administered through needle injections, by mouth and by aerosol. Vaccination is the injection of a killed or weakened organism that produces immunity in the body against that organism. Antimicrobials/ antibiotics/ antibacterial are the drugs used in the treatment and prevention of bacterial infections. They may either kill or inhibit the growth of bacteria. Few antibiotics possess antiprotozoal activity. Antibiotics are not effective against viruses such as the common cold or influenza and their inappropriate use allows the emergence of resistant organisms.
