Vergeire echoed vaccine czar and the National Task Force Against Covid-19 chief implementer Secretary Carlito Galvez Jr., who represented the government in signing the deal with British manufacturer, AstraZeneca, along with Go Negosyo founder and Presidential Adviser for Entrepreneurship Jose Maria Concepcion 3rd, who represented the private sector on Friday. "It is worth the risk to bet on these vaccines, I believe Astra and Oxford are a very reliable group and I think they will come through in the end", Concepcion said.
The discovery that the whole dose was so effective after one and a half doses was an accident, said Pascal Sariot, chief executive of AstraZeneca.
"The manufacturing process data that must be provided include the critical process parameters, critical quality attributes (like purity, identity, potency of the vaccine), batch records, defined hold times and the in-process testing scheme, in addition to having to submit the specifications for drug substance and drug product".
Two high-ranking officials at the World Health Organisation (WHO) consider that more profound data is needed on the efficiency of the vaccine developed by AstraZeneca and the University of Oxford. Efficacy in patients administered two full doses one month apart was 62 percent, while in those administered a half-dose and then a full dose, it reached 90 percent.
"Now that we've detected what seems to be better effectiveness, we need to validate it, so we need to do an additional study", Soriot said.
Oxford researchers said their produced vaccine has more than 70 percent results and is more effective than the seasonal flu shot.

The Federal Aviation Administration (FAA) approved the shipments, which require the vaccine candidate to be packed in dry ice, according to CNN .
Dr. Michael Gardam, an infectious disease specialist at Women's College Hospital in Toronto, said AstraZeneca nearly needs to start the clinical trial over again. "The real problem here is people are really on edge and any little tweak that happens, people worry about it and rightly so".
Britain now has access to enough doses of Moderna's vaccine candidate for around 3.5 million people.
"As a result of the historic pace of vaccine development through Operation Warp Speed and careful logistics planning, the FAA today is supporting the first mass air shipment of a vaccine", the agency said in a statement Friday.
A peer-reviewed analysis of data from the AstraZeneca-Oxford trial will be published in The Lancet in the coming weeks.
"It's possible that a lower initial vaccine dose could result in higher vaccine efficacy".
