Singapore has
placed orders for vaccines against the Sars-CoV-2 virus from multiple suppliers to hedge its bets, and has received supplies of the Pfizer-BioNTech and Moderna vaccines, which have been approved for use.
Late last month,
it received its first shipment of China's Sinovac vaccine, which has not yet been authorised by the Health Sciences Authority for use in Singapore. The agency is in the process of evaluating it for safety and efficacy.
With mass vaccination campaigns under way around the world giving rise to vaccine diplomacy - countries using vaccines as instruments of influence - some commentators have suggested that China may be pushing for Singapore to approve the Sinovac product.
Asked by BBC World News Asia Business correspondent Karishma Vaswani if Singapore was under pressure to use a Chinese-made vaccine, Mr Lee said: "We are in the process of evaluating the vaccine. If it passes muster in terms of safety and effectiveness, we will use it."
He added: "I do not think there is any basis for people to say, a vaccine comes from China, it is no good, or conversely, a vaccine comes from China, it must be good because I am a Chinaman and it matches my DNA. Vaccines are vaccines."
Mr Lee also noted that China has capable scientists, biomedical researchers and vaccine researchers, adding that he had no doubt they were capable of making good vaccines.
Since Singapore's Covid-19 vaccination drive kicked off last December, more than 610,000 doses of vaccines have been administered.
