  1. Jun 22, 2022 · The COVID-19 vaccine required an unprecedented effort - and more than just sleepless nights. In a special one-on-one-conversation at the World Economic Forum's Annual Meeting in Davos, Pfizer CEO Albert Bourla talked to founder Klaus Schwab about what the effort really required, including the type of trust and collaboration that could rely on verbal agreements in the short term when there was ...

  2. Dec 17, 2020 · Nine vaccinated participants became infected with the virus, compared with 169 individuals injected with the placebo, equating to 95% efficacy. Importantly, protection was high across different groups, regardless of age, ethnicity or underlying health conditions. The Pfizer/BioNTech vaccine for COVID-19 has reached the end of clinical trials ...

  3. Nov 11, 2020 · The new Pfizer COVID-19 vaccine that was found to be 90% effective will need to be refrigerated at -70 to -80 degrees. This creates a challenge for distribution and storage, as most hospitals can only refrigerate at around -2 to -8 degrees. At this temperature, the vaccine will spoil after five days. California has proposed building a ...

  4. Mar 30, 2021 · Messenger RNA (mRNA) is a set of genetic instructions for our cells to make the spike protein, which is found on the surface of the coronavirus. The adjuvants in mRNA vaccines are lipid or polymer-based nanoparticles that protect and stabilise the fragile mRNA and improve its uptake by our immune cells. Over 550 million COVID-19 vaccines have ...

  5. Nov 20, 2020 · Tackling COVID-19 will require the first-ever deployment of blockchain in the global distribution of a vaccine. Blockchain offers an immutable, decentralized database that can help all parties be sure that vaccine supplies are being stored and handled properly. In recent weeks, not one but two companies have announced COVID-19 vaccines with ...

  6. Nov 18, 2020 · Pfizer said there were 170 cases of COVID-19 in its trial of more than 43,000 volunteers and only eight people with the disease had been given the shot rather than a placebo, meaning the vaccine had a 95% efficacy rate. Of the 10 people who developed severe COVID-19, one had received the vaccine. “The data is very strong,” said Ian Jones, a ...

  7. Jul 25, 2021 · The Pfizer BioNTech and Moderna COVID-19 vaccines work differently from traditional vaccines so researchers wanted to know more about the immune system response. The second shot of a COVID-19 vaccine induces a powerful boost to a part of the immune system that provides broad antiviral protection, according to a study.

  8. Jan 4, 2022 · A vaccine has never been developed, tried, tested and manufactured faster than the COVID-19 vaccines have. More than 11 billion vaccine doses will be produced by the end of this year, with December production alone set to reach almost 1.5 billion doses. It’s even more important to rethink global vaccine distribution in 2022 in order to reduce ...

  9. Dec 7, 2021 · A new study shows mixing COVID-19 vaccines could make them more effective. A new study suggests different COVID-19 vaccines could be mixed. People have a better immune response when they received a first dose of AstraZeneca or Pfizer-BioNTech shots, followed by a Moderna dose, according to a new study. The findings are particularly important ...

  10. Jan 4, 2021 · This RNA vaccine – one of the world's first to be approved – was developed by US pharmaceutical giant Pfizer and its German partner BioNTech. Its active ingredient is messenger RNA, which is closely related to DNA and contains a synthetic version of COVID-19’s genetic code. Once injected, the patient’s immune cells follow the vaccine ...
