MANILA (UPDATE) - Sinovac and Pfizer-BioNTech led the list of preferred COVID-19 vaccines while majority of Filipinos overall prefer the US as their source of jabs, according to an independent Social Weather Stations survey released Monday.

The survey also found that Pfizer-BioNTech (43 percent) and Sinovac Biotech (41 percent) are equally chosen by respondents who answered that they prefer the US as their source of COVID vaccine.

Seventy-six percent who chose China as their preferred source also picked Sinovac Biotech as their preferred vaccine while Oxford-AstraZeneca was most popular among those who chose the United Kingdom, SWS said.

The national government earlier urged local authorities not to announce available vaccine brands after crowds trooped to inoculation sites without pre-registering.

Experts had warned that withholding the announcement of brands may however increase vaccine hesitancy among the public.

The Philippines aims to inoculate up to 70 million of its population by year-end to achieve herd immunity, vaccine czar Secretary Carlito Galvez said.

Government needs to conduct 500,000 daily inoculations in Metro Manila and 8 other economic hubs to achieve its target by November, he said.

The country has administered 4,097,425 COVID-19 vaccine doses as of Saturday. Some 949,939 Filipinos have been fully vaccinated while 3,147,486 have received their first dose.


For an infectious disease expert, the country's COVID-19 vaccination rollout is addressing vaccine hesitancy among Filipinos.

"We saw that many also preferred Sinovac and I think this is a proof that majority of those vaccinated with Sinovac got their first-hand experience of minimal adverse reaction," he told Teleradyo in a mix of Filipino and English.

Getting COVID-19 vaccines dispel myths and misinformation surrounding the jabs, he added.

"People should not refuse in taking it because what we are after here is the vaccine that will really save your life, not just getting the infection," added Solante, chief of the Adult Infectious Diseases and Tropical Medicine unit at the San Lazaro Hospital.

As of May 24, the country has administered over 4.3 million doses of COVID-19 vaccine, of which more than 3.3 million people received their first dose. Some 986,000 were fully vaccinated.
