COVID-19: Chinese vaccine, suggesting low efficacy: CCDC / Gao Fu
[April 11th AFP]
China Centers for Disease Control and Prevention (CCDC):
April 10th
To improve “the effectiveness rate of the existing new vaccine made in China is relatively low”
“We are considering the combination of different types of vaccines,” he said.
This is the first time that a top-level expert in China has publicly “suggested the ineffectiveness of a Chinese vaccine.”
The Paper:
CCDC Chief Gao Fu:
At a press conference in Chengdu, Sichuan Province, he said:
It is necessary to “consider a solution to the problem of low efficacy of Chinese vaccines.”
Vaccine made in China:
China
Under development of large-scale mass inoculation in Japan,
Moreover, it exports Chinese vaccines all over the world.
Mr. Gao pointed out that one of the solutions to the problem was to “alternately inoculate vaccines using different techniques.”
Question mark on Chinese vaccine:
Mr. Gao already has several vaccines in China.
However, he pointed out that “the existence of the mRNA vaccine should not be ignored.”
“China needs more vaccine development,” the Paper reports.
Effective rate of US / German vaccine:
US Pfizer
Germany BioNTech
US Moderna (Moderna)
The efficacy rates of the mRNA vaccine are 95% and 94%, respectively.
Effective rate of Chinese vaccine:
There are four vaccines approved for conditional use in China.
The effectiveness rate of Chinese vaccines is “lower than that of Pfizer Biontech and Moderna”
Moreover, “None made in China is an mRNA vaccine.”
4 Chinese vaccines:
Sinovac Biotech
In a clinical trial in Brazil, the efficacy rate was 50%.
Chinese Pharmaceutical Group (Sinopharm)
The effective rate is 79.34%.
CanSino Biologics
The efficacy rate was 65.28% 28 days after inoculation.

Chinese official says local vaccines ‘don’t have high protection rates’
What did Mr Gao say?
Gao Fu, head of the Chinese Centres for Disease Control and Prevention, on Saturday
said at a conference the current vaccines “don’t have very high rates of protection”.
He suggested that
the China was considering mixing Covid-19 vaccines, as a way of boosting efficacy.
Mr Gao explained that steps to “optimise” the vaccine process could include changing the number of doses and the length of time.
He also suggested combining different vaccines for the immunisation process.
But he later appeared to backtrack on his comments, telling state media Global Times that “protection rates of all vaccines in the world are sometimes high, and sometimes low”.
“How to improve their efficacy is a question that needs to be considered by scientists around the world,” he told the paper.
