They include pain and swelling at the injection site, fever, headache, nausea, diarrhoea, joint pain, cough, chills, sore throat and runny nose.

Should You Get Sinovac Vaccine For 5-11 Yo Kids?

This conditional approval of the Sinovac vaccine will be a relief for many parents who have been holding out for an alternative to the Pfizer COMIRNATY vaccine, and spur vaccination rates.

Back in October 2021, the KKM ran a Phase 3 clinical trial to determine the efficacy of the Sinovac COVID-19 vaccine for children 3-11 years in age.

However, the Malaysia Ministry of Health did not reveal what was the efficacy of the Sinovac COVID-19 vaccine for the 5-11 year old age group, or how it performed against the Omicron variant.

We do know that the adult dose was only 50.4% efficacious in preventing symptomatic COVID-19 from the original SARS-CoV-2 virus, and that it has zero efficacy against the Omicron variant (see link and table below).

Seropositive Rate MN Titer (GMT)
Pfizer Sinovac Pfizer Sinovac
HKU691 Omicron 20% 0% 5.43 Min.
24% 0% 6.42 Min.
Delta 100% 68% 124.7 10.3
Beta 100% 0% 25.7 Min.
Alpha 100% 100% 229.4 21.7

It seems very improbable that the same vaccine would impart better efficacy in children, more so against the Delta or Omicron variants.

Until there are good peer-reviewed Phase 3 results of the Sinovac CoronaVac vaccine for 5-11 year-old children, I believe it is far more prudent to vaccinate our children with the Pfizer COMIRNATY paediatric vaccine.

At least the Pfizer paediatric COVID-19 vaccine has been proven in a Phase 3 trial to be 90.7% efficacious in preventing symptomatic COVID-19 infections.

If you want the best protection for your child, get the new Pfizer vaccine for kids. Only consider the Sinovac vaccine if your child has an adverse reaction to the first dose of the Pfizer vaccine.
