The flu vaccine is not a new vaccine that is developed from scratch every year. The flu virus mutates rapidly into different strains, meaning that a vaccination from a previous year will not protect you for another year's strain. The vaccine is modified to take account of this - it is not developed from scratch every time.
The Salk vaccine was developed by Dr. Jonas Salk in the early 1950s. It is an inactivated poliovirus vaccine designed to protect against poliomyelitis. Salk's work was pivotal in reducing polio outbreaks and paved the way for widespread vaccination efforts. The vaccine was first made available to the public in 1955.
he was a scientist
The first vaccine was created by Edward Jenner in 1796. He developed the smallpox vaccine by using material taken from cowpox lesions, demonstrating that exposure to cowpox could provide immunity against smallpox. This groundbreaking work laid the foundation for the field of immunology and vaccination, ultimately leading to the eradication of smallpox.
Years before Jonas Salk's work, Dr. Albert Sabin developed a polio vaccine using live virus. The Sabin vaccine was used for 18 years before the government recommended using the Salk vaccine, exclusively.
it doesn't
the h1n1 vaccine does not work all the time
The anthrax vaccine was discovered by Louis Pasteur in the late 19th century. In 1881, he developed the first effective vaccine for anthrax, using a weakened form of the bacterium Bacillus anthracis. Pasteur's work laid the foundation for modern immunology and demonstrated the principle of vaccination. His groundbreaking research significantly contributed to the understanding and prevention of infectious diseases.
because it does
Dr. Jonas Salk was an American virologist who developed the first successful polio vaccine. His discovery of the polio vaccine in 1955 was considered a milestone in the fight against the disease and led to its eventual eradication in many parts of the world. Dr. Salk's work saved countless lives and revolutionized the field of public health.
Radioactivity was not developed, it has always existed. It was mostly the work of Madame Curie that paved the way for its use in many applications today. Unfortunately she died of radiation poison, though her work lives on.
because the immune system may not be strong enough to create antibodies also when a vaccine is used it could of weakened the immune system ...
Yes. They have found a vaccine that works 90 percent.
