Chimpanzees to the Rescue: AstraZeneca's Coronavirus Vaccine Trial Begins in Palm Beach County

Strategic Insights -

Chimpanzees, in the form of a cold virus engineered to carry a piece of the COVID-19 virus, are at the forefront of a novel approach to developing a coronavirus vaccine. The AstraZeneca-Oxford University vaccine, dubbed ChAdOx1 nCoV-19 (AZD1222), is set to begin Phase III trials in Palm Beach County, with up to 1,600 volunteers to be tested. This "viral vector-based" vaccine not only produces antibodies to counteract the virus but also triggers a robust killer T-cell response, providing a multi-layered defense against the deadly COVID-19 virus.

Key Takeaways:

  • AstraZeneca's vaccine, developed in collaboration with Oxford University, will be tested in a Phase III trial involving up to 1,600 volunteers in Palm Beach County.
  • The vaccine uses a chimpanzee cold virus as a Trojan horse to deliver the coronavirus protein, triggering both antibody and T-cell responses.
  • The trial will be conducted by the JEM Research Institute near JFK Medical Center, with recruitment ongoing through 561-770-7370.
  • The vaccine consists of two shots administered 29 days apart, with mild side effects reported in earlier human trials, including irritation and low-grade fever.
  • The trial will compare the effectiveness of the AstraZeneca vaccine against other candidates, with scientists monitoring the body's immune response and the presence of neutralizing antibodies.
  • Dr. Larry Bush, a renowned infectious disease specialist, will serve as the primary principal investigator for the trial.

Statistics:

  • Up to 1,600 volunteers will be recruited for the Phase III trial in Palm Beach County.
  • The vaccine has shown a robust killer T-cell response in earlier human trials, in addition to producing neutralizing antibodies.
  • 29-day interval between the two doses of the vaccine.
  • Mild side effects experienced in earlier trials include irritation around the shot location and low-grade fever for up to a day.
  • Over 160,000 people have been killed by COVID-19 in the United States.
