Vaccines Update – 16 June 2020

Moderna – Phase II
Moderna’s mRNA vaccine was tried on eight people in May, but experts gave a lukewarm response to its results. Part of Operation Warp Speed — a US govt programme funding five vaccines — the American company is eyeing Phase III trials in July and hopes to have vaccines ready by early 2021.

BioNTech – Phase I, Phase II
Another Warp Speed project. German company BioNTech is collaborating with USbased Pfizer and Chinese drug maker Fosun Pharma to develop an mRNA vaccine. Pfizer announced human trials in May, and hopes to have a few million doses for emergency use in Dec 2020.

Imperial College London – Phase I, Phase II
Imperial College London researchers have developed a ‘self-amplifying’ RNA vaccine, which boosts production of a viral protein to stimulate the immune system. They began Phase I/II trials on June 15 and have partnered with Morningside Ventures to manufacture and distribute the vaccine through a new company called VacEquity Global Health.

Inovio – Phase I
In May, American company Inovio published a study showing that their DNA-based vaccine produces antibodies in mice. Phase I trials are underway in the United States and will start in South Korea at the end of June.

Novavax – Phase I, Phase II
In May, US-based Novavax started Phase I/II trials on a vaccine made up of microscopic particles carrying fragments of coronavirus proteins. The Coalition for Epidemic Preparedness Innovations is investing $384 million in the project.

Clover Biopharmaceuticals – Phase I
Clover Biopharmaceuticals has developed a vaccine containing a protein from coronaviruses. The vaccine would be taken in conjunction with a so-called adjuvant, made by British drugmaker GSK, to further stimulate the immune system.

BCG Vaccine – Phase III
The Bacillus Calmette-Guerin vaccine was developed in the early 1900s to protect against tuberculosis. The Murdoch Children’s Research Institute in Australia is conducting a Phase III trial with it, and several other trials are underway to see if the vaccine partly protects against the coronavirus.

University of Oxford – Phase II, Phase III
Supported by Operation Warp Speed, the University of Oxford and the British-Swedish company AstraZeneca are developing a vaccine based on a chimpanzee adenovirus called ChAdOx1. It is going into phase II/III testing in England and Brazil, and may be ready.

CanSino Bio – Phase II
Chinese company CanSino Biologics is testing a vaccine based on the Ad5 adenovirus, in partnership with the Institute of Biology at the country’s Academy of Military Medical Sciences. In May, they published a paper in the Lancet — the first time Phase I trial data from any Covid-19 vaccine appeared in a scientific journal.

Sinovac – Phase I, Phase II
This private Chinese firm is testing an inactivated vaccine called CoronaVac. On June 13, it announced that Phase I/II trials on 743 volunteers found no severe adverse effects and produced an immune response. Sinovac is readying for Phase III trials in China and Brazil.

Sinopharm Phase I, Phase II
State-owned Chinese company Sinopharm has started Phase I/II trials on two inactivated vaccine viruses. The company has announced it has built a facility in Beijing to make up to 200 million doses per year.

Institute of Medical Biology – Phase I
Researchers at the Institute of Medical Biology at the Chinese Academy of Medical Sciences, which has invented vaccines for polio and hepatitis A, are running a Phase I trial of an inactivated virus vaccine for Covid-19 for emergency use by October.
