COVID-19 has been the ongoing science topic discussed today, from treatment to research to economic impact, every aspect of the world is being affected by this mass virus. While there are many studies of vaccines, a new vaccine by China’s “Clover Biopharmaceuticals” has proved to have a reason for standing out amongst the other vaccines scientists have been creating.
This vaccine has given protection against five different variants of the strain, including the new destructive delta variant. It has also been shown to lower risk of disease in those who have, and have not been infected with COVID-19 before. Since the vaccine is based on SARS-CoV-2 protein, instead of mRNA products, the vaccine can be refrigerated instead of frozen. This shot also contains something called spike, an immune stimulant produced in hamster ovaries, which helps in boosting those who receive the vaccine immune system.
In Clover’s trial, 30,000 citizens from four different continents were observed after their vaccine was given to them. Those who did not have COVID-19 before had an efficacy of 67.2%, an efficacy of 83.7% regarding moderate to severe disease, and 100% efficacy when looking at hospitalization & death. Efficacy against the delta variant was 78.7%, while efficacy against a variant called Mu was only 58.6%.
For those who have had COVID-19 before, there was an efficacy of 64.2% in preventing another infection of COVID-19. This just so happens to be the first efficacy study that has been able to prove the importance of being vaccinated even when being exposed. Even though this is still a work in progress, this could be another big breakthrough for SARS-CoV-19 immunizations.

Hi there, I like that you chose to discuss a very relevant current topic. I think this was very informative as a vaccinated person, and enjoyed reading the statistics.

DeleteWhat stood out to me about this vaccine is not only does it fight against COVID-19 but also boost people's immune systems. But for me to better gauge it's effectiveness in the trial, how do the statistics of this vaccine compare to the vaccines that are being more widely used, like moderna and pfizer?

DeleteI haven't been able to find specific research comparing the effectiveness rates of Clover's vaccine & those that are more commonly used. I did find a website that mentioned a company investing in Clover's vaccine to sell more than 400 million doses, which is the same vaccine pool that that has made deals with Pfizer, Moderna, Johnson & Johnson, and other widely used COVID-19 vaccines. This implies the hope of equivalent effectiveness based on the studies already done on this vaccine.

I think this post was really well written. Very nice to read. The ability to refrigerate the vaccine, as opposed to freezing with the mRNA vaccines, will probably massively help with vaccine distribution globally. Getting vaccines to countries without the infrastructure to sustain so many freezers will help slow the spread globally and save lives. Hopefully this now vaccine is safe and ready to roll out to those who need it soon

That's my hope too! Since more wealthier countries claimed most of the first vaccines released to the public, there aren't many options for those in middle to low income countries. This new vaccine could play a huge factor in reining in the pandemic globally.

I hope that the Clover Biopharmaceuticals can be the solution to end this pandemic. I wonder what aspects of this vaccine makes it different from the other vaccines. According to the statistics, it works really well, but I'm still confused on how it works.

From my understanding, this vaccine is a protein based vaccine, while the other vaccines we see being widely used in the US are mRNA vaccines. The mRNA vaccines tell our bodies how to make certain proteins that will trigger certain immune responses inside our body. The protein based vaccine helps our body recognize the COVID virus, and create antibodies more readily.

I really enjoyed reading this. I was wondering if they reported any complications with the vaccine? That is surely a hot topic right now with some resistance to the other vaccines. It is interesting how many new vaccines have come out I am excited to read about others. - Shannon Gray
