VERA FILES FACT CHECK: To boost trust in Sinovac, Roque repeatedly cites wrong data

In at least three separate briefings, Presidential Spokesperson Harry Roque misstated the interim clinical trial results of Indonesia on CoronaVac, a vaccine against the coronavirus disease 2019 (COVID-19) developed by Chinese firm Sinovac BioTech.

Roque’s claims on Sinovac in his Jan. 14 briefing were made to address criticisms that the government is “favoring” the China-made vaccine over other candidates that have reported higher efficacy rates at supposedly cheaper prices.

In recent back-to-back hearings on the national immunization program, senators pressed government officials on the move to secure 25 million doses of Sinovac COVID-19 jabs despite allegations of overpricing and the fact that it has yet to be issued an emergency use authorization (EUA) by the Food and Drug Administration (FDA).

Sinovac applied for an EUA in the country on Jan. 13 but has yet to submit data on its phase 3 clinical trials for evaluation, the FDA said in a Jan. 14 media forum. As of Jan. 21, only Pfizer-BioNTech’s COVID-19 vaccine has been granted a permit for emergency use in the country.

What is ‘vaccine efficacy’?

Vaccine efficacy is the term used to “report on how well a vaccine works to prevent a particular disease in controlled, research environments,” according to a global team of public health experts convened by international nonprofit Meedan.

It pertains to “how well the vaccine prevents the virus in the research vaccine group” compared to participants in the trial who did not receive the treatment, Meedan experts said. It does not describe how well the vaccine works on the general public in real-world conditions, they added.
