- Dangerous for frail patients
10 Dead in Germany after Receiving Pfizer COVID-19 Vaccine.
Initial cases reported in Norway had raised alarm. Sigurd Hortemo, chief physician at the Norwegian Medicines Agency, said the assessments of the deaths suggest that common adverse reactions to mRNA vaccines, such as fever and nausea, may have aggravated underlying illnesses and contributed to a fatal outcome in some frail patients.
- Impossible distribution and storage conditions, low effective rate
The Pfizer/BioNTech vaccine must be kept at –70℃ and can be kept in a regular fridge for just 5 days. It will be hard enough for many places within the United States to manage Pfizer’s super-cold vaccine, says Mei Mei Hu, cofounder and cochief executive of Covaxx, a company based in Hauppauge, N.Y., that is working on its own COVID-19 vaccine. And “if it’s difficult in the U.S., it’s going to be virtually impossible in most emerging markets,” such as Central and South America and many places in Africa, she says.
According to the WHO, up to 50% of vaccines will become ineffective and be wasted globally due to inadequate logistics infrastructure, which could translate to the loss of billions of vaccine doses, and even millions of lives. Other coronavirus vaccines in development will not need to be stored at ultra-cool temperatures.
- Immature technology
Pfizer has never manufactured a vaccine with technology that uses mRNA, but it has scaled up production capacity even as research was still under way.

If you have a choice, which Covid vaccine you would opt for and why?
If you are not given a choice, will you rather delay vaccination until your chosen vaccine is available?
I understand some people prefer no vaccine, which is a valid choice too - until that option is effectively removed by digital vaccine passport route.
