Would you inject 50 hookworms under your skin for your job? Or steam in a vomit sauna for a few hours? Hopefully we non-scientists will never have to answer questions like these. But for the 10 brave souls on this list, experimenting on themselves was all in a day s work.
1. Jonas Salk
During his research at the University of Pittsburgh Medical School, Dr. Jonas Salk discovered a potential vaccine for polio. When they needed healthy human test subjects, Salk volunteered himself and his entire family for a vaccine trial. The filial gamble paid off. Everyone tested positive for antibodies against the virus. He refused to patent the vaccine, and never received financial compensation for his discovery. (When Edward R. Murrow asked Salk who owned the patent on the vaccine, Salk responded with one of his most famous quotes: “Well, the people, I would say. There is no patent. Could you patent the sun?”) ....

Louise Carroll: Unicorns, flowers and spending time in Ellwood City
By Louise Carroll
Special to The Ledger
I m sure more happens in my mind than in my life. My mind is free to go anywhere. It has no limits, it can think anything, imagine anything and create anything. Many times I m very grateful people can t read my mind, but my mind is also inspired by things I hear, see and read and I just have to write them down. My compulsion becomes the Random Column.
April 9 was National Unicorn Day. I m not sure how to celebrate the holiday, but I received a card last year from my friend, Dee Kammermier, who lives in New York. It said. I believe in you and unicorns, but especially you. ....

Coronavirus: Confusion over efficacy of Chinese vaccines | Science| In-depth reporting on science and technology | DW


Indonesia begins coronavirus vaccine rollout
CanSino s fourth Chinese vaccine is a vector vaccine based on an adenovirus type 5, making it comparable in mode of action to AstraZeneca s vaccine. It is expected to achieve an efficacy of 65%.
In principle, the efficacy values improve even further to over 80% when only severe courses  of disease are taken into account, namely those that also require hospitalization.
Combination of vaccines not unusual
The idea of combining vaccines to increase efficacy is not fundamentally new. Scientists are currently discussing similar approaches for AstraZeneca s vector vaccine.
And the Russian vaccine Sputnik V  also consists, strictly speaking, of two vaccinations with different vector vaccines based on different adenoviruses. The developers hope that this will lead to greater efficacy. ....
