Current vaccines offer "low protection" against the coronavirus but mixing different doses of alternatives could help boost effectiveness, China's top disease control official has said.
We will solve the issue that current vaccines don't have very high protection rates
Vaccine efficacy rates need to be improved, Gao Fu, director of the Chinese Centre for Disease Control and Prevention, said at a conference on Saturday, in rare comments from a senior Chinese health official claiming that current vaccines may be insufficient to halt the pandemic.
Explaining the factors that reduce vaccine effectiveness, Mr Gao said that the intervals between first and second doses need to be carefully considered.
"I suggest that we consider adjusting the vaccination process, such as the number of doses and intervals and adopting sequential vaccination with different types of vaccines," Mr Gao said in a presentation on Chinese Covid-19 vaccines and immunisation strategies, in China's south-western city of Chengdu.
“We will solve the issue that current vaccines don’t have very high protection rates. It’s now under consideration whether we should use different vaccines from different technical lines for the immunisation process.”

He also praised the benefits of mRNA vaccines – the technology behind the two Covid-19 vaccines seen as the most effective, Pfizer-BioNTech and Moderna – months after questioning whether the then-unproven method was safe.
While many vaccines introduce a weakened or inactivated germ to trigger an immune response – producing antibodies, mRNA vaccines teach the body's cells to make a protein that triggers the immune response.
"Everyone should consider the benefits mRNA vaccines can bring humanity," Mr Gao said. "We must follow it carefully and not ignore it just because we already have several types of vaccines already."
Chinese health officials at a news conference on Sunday did not respond directly to questions about Mr Gao's comments or about possible changes in official plans.
However, another China CDC official said Chinese developers are working on mRNA-based vaccines.
“The mRNA vaccines developed in our country have also entered the clinical trial stage,” said the official, Wang Huaqing. He gave no timeline for possible use.
Mixing Covid-19 vaccines
Experts say mixing vaccines – known as sequential immunisation – might boost effectiveness.
Researchers in Britain are studying a possible combination of Pfizer-BioNTech and the AstraZeneca vaccine.
Chinese vaccine effectiveness
China currently has five vaccines in use in its mass immunisation campaign, three inactivated-virus vaccines from Sinovac and Sinopharm, a one-shot vaccine from CanSino, and the last from Mr Gao’s team, in partnership with Anhui Zhifei Longcom.
The effectiveness of the vaccines range from just over 50 per cent to 79 per cent, based on what the companies have said.
The vaccine co-produced by Mr Gao's team was given emergency use approval a month ago. The team behind it have not yet publicly disclosed data about its efficacy.
Pfizer's and Moderna's vaccines have both been shown to be about 95 per cent in protecting against Covid-19 in studies, although this varies among age groups and depending on Covid-19 variants.

Pharaoh's curse
British aristocrat Lord Carnarvon, who funded the expedition to find the Tutankhamun tomb, died in a Cairo hotel four months after the crypt was opened.
He had been in poor health for many years after a car crash, and a mosquito bite made worse by a shaving cut led to blood poisoning and pneumonia.
Reports at the time said Lord Carnarvon suffered from “pain as the inflammation affected the nasal passages and eyes”.
Decades later, scientists contended he had died of aspergillosis after inhaling spores of the fungus aspergillus in the tomb, which can lie dormant for months. The fact several others who entered were also found dead withiin a short time led to the myth of the curse.

Teachers' pay - what you need to know
Pay varies significantly depending on the school, its rating and the curriculum. Here's a rough guide as of January 2021:
- top end schools tend to pay Dh16,000-17,000 a month - plus a monthly housing allowance of up to Dh6,000. These tend to be British curriculum schools rated 'outstanding' or 'very good', followed by American schools
- average salary across curriculums and skill levels is about Dh10,000, recruiters say
- it is becoming more common for schools to provide accommodation, sometimes in an apartment block with other teachers, rather than hand teachers a cash housing allowance
- some strong performing schools have cut back on salaries since the pandemic began, sometimes offering Dh16,000 including the housing allowance, which reflects the slump in rental costs, and sheer demand for jobs
- maths and science teachers are most in demand and some schools will pay up to Dh3,000 more than other teachers in recognition of their technical skills
- at the other end of the market, teachers in some Indian schools, where fees are lower and competition among applicants is intense, can be paid as low as Dh3,000 per month
- in Indian schools, it has also become common for teachers to share residential accommodation, living in a block with colleagues

WHAT IS A BLACK HOLE?
1. Black holes are objects whose gravity is so strong not even light can escape their pull
2. They can be created when massive stars collapse under their own weight
3. Large black holes can also be formed when smaller ones collide and merge
4. The biggest black holes lurk at the centre of many galaxies, including our own
5. Astronomers believe that when the universe was very young, black holes affected how galaxies formed
