Why do vaccines fail?
Abstract. There are two main reasons for failure of immunizations: (1) failure of the vaccine delivery system to provide potent vaccines properly to persons in need; and (2) failure of the immune response, whether due to inadequacies of the vaccine or factors inherent in the host.

What Did Edward Snowden Do to Come Forward?
He was probably the only person in the intelligence community who had access to all the files he was going to leak, so it wouldn’t take the intelligence community long to figure out he was the source. The only way to avoid this would have been to share fewer files, which would have weakened his story.
What did Edward Snowden do to get to the classified version of the report?
What did Edward Snowden do to get to the classified version of the report? The classified version found him. Because Ed was a sysadmin, whenever someone accidentally saved a draft copy of something they shouldn’t have, the system alerted him. The most confidential files had labels called “dirty words” that indicated that the file shouldn’t be stored outside of high-security drives. Whenever the system encountered a dirty word, it would notify the sysadmin—in this case, Ed—so he could get rid of it. He was expected to take a look at flagged files to make sure they weren’t flagged by accident.

It was the continued advocacy of the English aristocrat Lady Mary Wortley Montague (Figure (Figure22)that was responsible for the introduction of variolation in England (10). In 1715, Lady Montague suffered from an episode of smallpox, which severely disfigured her beautiful face. Her 20-year-old brother died of the illness 18 months later. In 1717, Lady Montague's husband, Edward Wortley Montague, was appointed ambassador to the Sublime Porte. A few weeks after their arrival in Istanbul, Lady Montague wrote to her friend about the method of variolation used at the Ottoman court. Lady Montague was so determined to prevent the ravages of smallpox that she ordered the embassy surgeon, Charles Maitland, to inoculate her 5-year-old son. The inoculation procedure was performed in March 1718. Upon their return to London in April 1721, Lady Montague had Charles Maitland inoculate her 4-year-old daughter in the presence of physicians of the royal court.

Jenner led the way in immunology, as antibodies are also key in the treatment of allergies and AIDS, or in vaccines for yellow fever, influenza, tuberculosis and perhaps soon malaria.

After that, they became actually protected against human smallpox.
Did Jenner do a repeat of the experiment?
Despite the success, Jenner wanted to repeat the experiment. He had to wait two years until he found another case of cowpox and only then did he publish the results of his tests, equivalent to today’s clinical trials. His is an example of scientific perseverance and method, but also of an audacity that led him to be thought mad 220 years ago and that today would have landed him behind bars for experimenting on a child. However, Jenner was not a reckless genius who came up with the idea of vaccination in a ‘Eureka moment’. Variolation, or the inoculation of smallpox scabs or pus into healthy people to protect them from what was then a terrible plague, was already being practised in his time. Sometimes variolation worked, but in other cases the outcome was fatal.
