Answer:
vaccine
Explanation:
British physician and biologist Edward Jenner was born in Berkeley, County Gloucestershire on May 17, 1749. He was the fourth son of Reverend Jenner, vicar of Berkeley.
At that time, smallpox was a very feared infectious plague that whipped Europe and America fundamentally, and for which there was no treatment or way to prevent it. It was caused by the Variola virus, although at that time it was not known.
Jenner observed that cows suffered from a disease called Vaccina or cowpox, which causes rashes in udders similar to those produced by human smallpox.
“He tested his vaccine with an 8 year old boy”
Sometimes they spread the disease to the milkmaids, in which pustules appeared on the hands. Fortunately, it was a benign condition and those affected soon recovered with very few sequelae.
But what really caught Jenner's attention was that these people became immune against human smallpox.

Answer:
The flu virus changes every year.
Explanation:
The virus that causes the flu mutates rapidly. Each year, a different flu strain causes the flu, which explains why you need to get a new flu shot every year. The antibodies you produced in response to last year's flu shot won't protect you from this year's flu. It is difficult to keep up with a quickly evolving virus like the influenza virus.
Doctors recommend annual flu shots to deal with the constant evolution and mutation of flu viruses. The rapid mutation rate of the flu virus requires the development of new vaccines each year to combat emerging strains. This process allows the flu shots to help control and mitigate flu outbreaks.
Doctors recommend getting flu shots each year due to the constant evolution and mutation of influenza viruses. Each year, scientists across the globe try to predict the flu strains that will be the most widespread and harmful. This prediction is based on how flu strains have evolved over time and over the past few flu seasons.
Several viruses, such as the flu, mutate and replicate at a rapid pace. The vaccine developed to protect against last year's flu strain may not offer protection against the coming year's strain due to the virus's evolution and adaptation.
The high rate of mutation in flu viruses makes it particularly difficult for the immune system to recognize different strains. Although the body may develop immunity to one strain through natural exposure or vaccination, new strains keep emerging that the immune system won't recognize.
The virus's surface molecules mutate, causing the flu to alter sufficiently each year such that the previous year's vaccine may not protect against the coming year's common flu. Therefore, new vaccine formulations need to be derived for each flu season.
Every year, new flu vaccines are developed to be effective against the expected dominant strains. These strains are typically cultivated in eggs and used to produce either an inactivated or a live attenuated vaccine. Through this process, annual flu shots aid in controlling influenza outbreaks.
