Among the countries with both high vaccination rates and high Covid-19 infection rates, most rely on vaccines made in China, a CNBC analysis shows.

The results come like the effectiveness of Chinese vaccines faces increasing scrutiny, aggravated by missing data to protect against the more transferable delta variant. CNBC found that weekly population-adjusted Covid cases have remained elevated in at least six of the world’s most heavily vaccinated countries – and five of them rely on vaccines from China.

As of July 6, CNBC identified 36 countries with more than 1,000 new confirmed cases per million people weekly based on numbers from Our world in data, which compiles information from sources such as the World Health Organization, governments and researchers at Oxford University. CNBC then identified countries among those 36 where more than 60% of the population had received at least one dose of the Covid vaccine.

There were six countries and five of them use Chinese vaccines as an essential part of their national vaccination programs: United Arab Emirates, Seychelles, Mongolia, Uruguay and Chile. The only country among them that doesn’t depend on Chinese vaccines is that United Kingdom.

The UK has now approved vaccines from Moderna, AstraZeneca-Oxford, Pfizer-BioNTech and Janssen. UK Covid cases have increased in recent weeks as the more transferable delta variant has spread there.

Sinopharm and Sinovac did not respond to CNBC requests for comment.

Several factors can lead to an increase in Covid cases in countries with high vaccination rates. Vaccines do not offer one hundred percent protection, so those who are vaccinated can still get infected. At the same time, new variants of the coronavirus might prove better at overcoming vaccines.

The best option for many countries

Still, countries shouldn’t stop using Covid-19 vaccines from China, epidemiologists say, especially when vaccine supplies are limited in low- and middle-income countries.

Many of the countries and territories that have approved Sinopharm and Sinovac vaccines are developing countries that cannot compete with wealthier countries for vaccines developed in the United States and Europe.

Ben Cowling, a professor in the University of Hong Kong’s School of Public Health, said countries could choose to use certain vaccines depending on their long-term goals.

“Some countries may accept low prevalence as long as there are relatively few serious cases and deaths from COVID-19,” Cowling, who heads the school’s epidemiology and biostatistics department, told CNBC in an email. “That should be achievable with a high coverage of all available vaccines.”

However, some countries avoid vaccines in China. Costa Rica last month refused to deliver vaccines Developed by Sinovac after it was completed is not effective enough.

WHO approval

The World Health Organization has approved Sinopharm and Sinovac vaccines for emergency use.

The effectiveness of the two Chinese vaccines is less than that of PfizerBioNTech and Modern, both of which have shown greater than 90% effectiveness.

Sinopharm’s vaccine is 79% effective against symptomatic Covid infections, the WHO says, but its effectiveness in certain groups – such as people over 60 – is not clear. The Effectiveness of Sinovac’s shot depending on the country in which the proceedings took place, from around 50% to over 80%.

Experts say that the results cannot be directly compared between clinical trials because each study is structured differently. However, a study in Hong Kong found “significantly higher” antibody levels in people who received the BioNTech injection compared to those who received the Sinovac vaccine This was reported by the South China Morning Post.

Some experts suggest that the technology behind the various Covid vaccines could explain differences in their effectiveness.

Sinopharm and Sinovac vaccines trigger an immune response by exposing the body to a weakened or “inactivated” virus – a best practice which has been used by vaccines for decades. Pfizer-BioNTech and Moderna based their vaccines on a technology called messenger RNA, which instructs the body to make viral proteins that trigger an immune response.

“Inactivated vaccines are easy to make and are known for their safety, but tend to have a weaker immune response compared to some other vaccine types,” said Michael Head, Senior Research Fellow on Global Health at the University of Southampton in the UK. wrote in an article published on the Conversation website.

Still, large phase three clinical trials showed that inactivated vaccines were “highly effective against serious illness and death” from Covid, Cowling said.

The professor told CNBC that the spikes in Covid cases in some countries using Chinese vaccines “are typically an increase in mild infections with very few severe cases in fully vaccinated people”.

‘Herd Immunity’

When vaccines are less effective, more people need to be vaccinated to achieve “herd immunity”. This happens when the virus stops being transmitted quickly because most people are immune to a vaccination or have recovered from an infection.

Some countries decided to try to achieve herd immunity at the beginning of the pandemic, but are not known to have succeeded. Some who said they would achieve herd immunity like Swedento be at the end affected by Covid much harder than neighboring countries that went the vaccination route.

A study by the Kirby Institute at the University of New South Wales Wales in Sydney claimed that in New South Wales, Australia, herd immunity could be achieved if 66% of the population were given vaccines with 90% effectiveness against all infections.

The percentage of the population who needs to be vaccinated increases to 86% when vaccine effectiveness is 70%, and herd immunity is not achievable when vaccine effectiveness is below 60%, the study showed.

Native theatres depend on grant cash to outlive

IRON MOUNTAIN, Michigan (WLUC) – Live venues across the country may be among the companies hardest hit by the pandemic. The Braumart Theater in Iron Mountain has been closed for over 10 months.

Friends of the Braumart board member, Fay Mannon-Rahoi, says since the board cannot host events, it has cut the theater’s funding.

“It affects our incoming dollars, our franchise booths, and just the entire community,” she said. She says that’s why the board applied for grants from the state and even local foundations. “We have received the grants that will allow us to buy cameras, microphones and everything we need for streaming in the future,” said Mannon-Rahoi. She says the theater also uses virtual cinema … which allows customers to rent movies and watch from home, but Mannon-Rahoi says she still believes the industry will return. “We’re just in a doldrums, we’re going to come back and we’re going to come back bigger and better because now we would be ready to really do more,” she explained.

Angie Dohl, the manager of the Crystal Theater in Crystal Falls, says that is why the board worked on renovating the historic theater. “We’re in the process of replacing all of our rigging, our movie screen, and the infrastructure that keeps lights and the like backstage,” she said. She says because the theater’s programming cost doesn’t exist. Any money received can be used for updates. To support this, the nonprofit raised nearly $ 7,000 in grants. “Whatever the piece, on one particular issue, the overhaul of the sound system is a matter for the local utility company,” she said. During this time, both theaters are always looking for donations and volunteers.
