The legacy of this era lives on to the present day in supply crises and continued media efforts by a growing vociferous anti-vaccination lobby. The past two decades have seen the application of molecular genetics and its increased insights into immunology, microbiology and genomics applied to vaccinology.
Current successes include the development of recombinant hepatitis B vaccines, the less reactogenic acellular pertussis vaccine, and new techniques for seasonal influenza vaccine manufacture.
Molecular genetics sets the scene for a bright future for vaccinology, including the development of new vaccine delivery systems e. DNA vaccines, viral vectors, plant vaccines and topical formulations , new adjuvants, the development of more effective tuberculosis vaccines, and vaccines against cytomegalovirus CMV , herpes simplex virus HSV , respiratory syncytial virus RSV , staphylococcal disease, streptococcal disease, pandemic influenza, shigella, HIV and schistosomiasis among others.
Therapeutic vaccines may also soon be available for allergies, autoimmune diseases and addictions. Skip to main content. Search form.

The main sign of smallpox is a rash that starts as flat red spots that turn into blisters.
Other symptoms include fever, headache, fatigue, and vomiting. Smallpox is spread from person to person through infected droplets. It is important to know that the last naturally occurring case of smallpox in the world happened in The World Health Assembly said the disease was completely eradicated in The smallpox vaccine was created to protect against infection.
It helps our bodies develop immunity to the smallpox virus. It cannot cause smallpox. However, it has been known to cause reactions in certain groups of people, such as:. The smallpox vaccine is no longer available to the public. In , routine smallpox vaccination in the United States ended. Today, the smallpox virus only exists in samples in research laboratories.
The vaccine still is used to protect certain people, like those who work with the virus. The United States also has a supply of smallpox vaccine available in case of an outbreak, which is unlikely.
If you got vaccinated before , you are no longer protected. People who are being vaccinated for the first time have a stronger reaction than those who are being revaccinated. The following pictures show the progression of the site where the vaccine is given in someone who has not gotten the vaccine before. Because the vaccinia virus is live, it is important to follow care instructions for the vaccination site. You can spread the vaccinia virus by touching the vaccination site before it has healed or by touching bandages or clothing that have been in contact with the live virus from the vaccination site.
If you do not follow these instructions, you can spread the virus to other parts of your body or to other people. Section Navigation.
