Sinovac Vaccine


Sinovac is now part of National Immunisation Programme


Under the National Vaccination Programme, eligible patients will be able to receive free booster vaccines at our clinic. Those who have already paid in advance for vaccines to be given after 23 October 2021 will be reimbursed. Those who do not qualify under the new Government scheme can still receive the vaccine but have to pay $70 per dose (GST included).


Patients who have never taken any vaccines before, may proceed to Government vaccination centres and designated clinics to receive all 3 doses free.  If they choose to receive all 3 vaccines at Precious, they will have to pay for it and the Government will not reimburse them。

Sinovac COVID-19 Vaccine 

The Sinovac vaccine uses an inactivated COVID-19 virus to teach your body's immune system to make antibodies against the actual COVID-19 virus.  The World Health Organisation (WHO) has validated Sinovac for emergency use in persons aged 18 and above as the known benefits outweigh the possible risks. While there is insufficient data to assess its safety in pregnant women, WHO concluded that as the vaccine is an inactivated vaccine similar to others used in pregnancy, its use is recommended when benefits outweigh the risks. Pregnant women, especially those aged 35 and above or who have medical conditions are at higher risk of developing severe COVID-19. Its use in breastfeeding mothers is also recommended on a similar basis.



Serology are blood tests which check the response of our body's immune system to the vaccine. While the routine use of blood tests is not essential before vaccinations, these tests do provide us a snapshot of our response to the vaccine and are available for those who wish to do so. These include:

  • Anti-S: a numeric count of all binding antibodies against the "Spike" or "S" antigen found on the virus.

  • cPass™: tests for presence of neutralizing antibodies against the specific section of the "S" antigen that penetrates cells. 

  • Anti-N: tests for antibodies against a different part of the virus which may be induced after natural infection or inoculation with inactivated vaccine.

*    Besides an antibody response, our body also has other methods of protecting itself against viruses. Antibody tests do not equate to protection.

 ** mRNA vaccines target only the S antigen and anti-N tests in these patients will be negative whereas some patients using inactivated vaccines 

 may get a positive response to the anti-N test.
