From the article:
“It has become commonplace to describe the speed with which vaccines were devised for Covid-19 as unprecedented. But it was not. The first New York Times report of the outbreak in Hong Kong—three paragraphs on page 3—was on April 17, 1957. By July 26, little more than three months later, doctors at Fort Ord, Calif., began to inoculate recruits to the military.
Surgeon General Leroy Burney announced on August 15 that the vaccine was to be allocated to states according to population size but distributed by the manufacturers through their customary commercial networks. Approximately 4 million one-milliliter doses were released in August, 9 million in September and 17 million in October.
This amounted to enough vaccine for just 17% of the population, and vaccine efficacy was found to range from 53% to 60%. But the net result of Hilleman’s rapid response to the Asian flu was to limit the excess mortality suffered in the U.S.”
it took 4 to 6 months from the time of the outbreak in Asia to the Asia flu shot to be available in the US.
It took 12 months from the time of the outbreak in China to the Wuhan virus shot to be available in the US.
Vaccines killed more people back then. They test now, because they should. Vaccines had been 60% effective back then, but he is not giving you the rate of health issues and even death from the vaccine. Do a search on Cutter or Simian Virus. The 1950s was not a golden era for vaccines.
