Porter W. Anderson Jr. and David Hamilton Smith were two of the four scientists principally responsible for developing the Haemophilus influenzae type b (Hib) vaccine. Their work transformed Hib from a leading cause of childhood meningitis into a largely vaccine-preventable disease
Their research began in the late 1960s at Boston Children's Hospital, where they investigated why Hib caused severe infections in infants and young children. Anderson, a microbiologist, and Smith, a pediatric infectious disease specialist, identified the bacterium's capsular polysaccharide—polyribosylribitol phosphate (PRP)—as the critical antigen capable of inducing protective immunity.

Ivermectin traces its origins to a soil sample collected in Japan.
Satoshi ÅŒmura isolated a previously unknown bacterium, Streptomyces avermitilis (now Streptomyces avermitilis), from the soil.
The bacterium produced compounds called avermectins, which showed powerful activity against parasitic worms
Ivermectin was first marketed in 1981 as a veterinary medicine. It proved highly effective against a wide range of internal and external parasites in cattle, horses, sheep, and other animals. It rapidly became one of the most successful veterinary drugs ever developed.
After successful clinical trials, ivermectin was approved for human use in 1987, particularly to treat:
Current Events
July 24th is World Ivermectin Day, a decentralized, bottom-up, citizen-driven movement established by an international coalition of medical professionals, journalists, musicians, and artists. They aim to share the evidence-based message that cheap, safe, and easily distributed medicine - which is already deployed by two dozen countries - can remove the fear of the COVID-19 pandemic to lives and economies. The event was started in 2021 by a team of volunteers, featuring online talks and discussions available to millions. Last year, their content was censored by Youtube because ivermectin is not supported by health authorities for prevention and treatment.
On July 24, 1969, Apollo 11 returned to Earth, ending its historic moon-landing mission.
After the spacecraft's splashdown in the Pacific Ocean, astronauts Neil Armstrong, Buzz Aldrin and Michael Collins were flown by helicopter to the recovery ship USS Hornet.
Operation Gomorrah began on July 24, 1943, marking the start of a fierce joint air-raid campaign on Hamburg, Germany, by British and American forces.
