- Tuberculosis
The Answer:
And, the answer for the the question is :
Explanation:
On April 12, 1955, Dr. Thomas Francis Jr., director of the Poliomyelitis Vaccine Evaluation Center, said that the polio vaccine produced by American virologist Jonas Salk was safe and effective. In the United States alone, the disease that caused an annual average of 15,000 instances of paralysis in the 1950s was nearly eradicated within 25 years. Before his untimely death in 1995, Salk focused his remaining energy on developing an AIDS vaccine.
Jonas Salk is one of the most important figures in the history of medicine. Born in 1914 in New York City, he was a virologist and medical researcher who is best known for his work on the polio vaccine. Salk’s discovery of the vaccine was a major breakthrough in the fight against polio, a disease that had plagued humanity for centuries.
Polio is a highly infectious disease that attacks the nervous system and can cause paralysis and even death. Before the vaccine was discovered, there was no cure for polio, and the disease was a major public health crisis. It primarily affected children, and outbreaks were common during the summer months.
Salk began his work on the polio vaccine in the 1940s. He believed that the best way to prevent the disease was to create a vaccine that would stimulate the body’s immune system to fight off the virus. He developed a vaccine that used an inactivated form of the polio virus, which was much safer than previous vaccines that used live, weakened strains of the virus.
Salk’s vaccine was first tested in 1952 in a large-scale trial involving more than one million children. The trial was a resounding success, with the vaccine proving to be safe and effective in preventing polio. The results of the trial were announced in 1955, and the vaccine was quickly approved for widespread use.
The discovery of the polio vaccine was a major turning point in the fight against the disease. It marked the beginning of the end for polio, and within a few years, the number of cases had dropped dramatically. Today, thanks to the vaccine, polio has been eradicated in most parts of the world, and it is on the brink of being completely wiped out.
Salk’s discovery of the polio vaccine was a major achievement, and he became a hero to millions of people around the world. He went on to receive numerous awards and honors for his work, and he continued to dedicate his life to medical research until his death in 1995. Today, his legacy lives on through the millions of people who have been saved from the devastating effects of polio, thanks to his groundbreaking work.
