Experts and governments in most countries of the world are working to launch the vaccine and see it as a light at the end of the tunnel. It is not yet clear how the vaccine will work and for how long. Even in people who have had covid-19, it is not clear how long the antibodies will last.

“The vaccine offers great hope that it could end the pandemic, but we know that the history of vaccine development is fraught with failure,” said Dr. Fiona Culley of the National Institute of Heart and Lung at the Royal University of London.

Vaccination will be slow
The Royal Society warns that the introduction of the vaccine will take time. “Even if a vaccine is available, it does not mean that everyone will be vaccinated within a month. We are talking about six, maybe nine months or even a year, “said Professor Nilay Shah, who heads the Department of Chemical Engineering at the Royal University. “It’s not like life suddenly returns to normal in March,” he added.

The report also points out that there are still many unresolved issues in vaccine development. For example, so-called RNA vaccines, which use parts of the virus’s genetic information, have never been mass-produced. The so-called Again, mRNA vaccines have never been approved for use.
–
There is also the issue of storage, some vaccines require storage at -80 ° C. It is also a sufficient number of raw materials for the production of vaccine and ampoules.

Professor Shah estimated that vaccination would have to take place ten times faster than the flu, which would require 30,000 trained workers in Britain alone. She’s worried if that’s all been thought about.

Charles Brown, head of immunology at Royal University, summed up the problems: “We just don’t know when an effective vaccine will be available, how effective it will be, and of course, which is key to how quickly it can be distributed. We will therefore have to gradually relax some measures. “
–
A complication may also be that one dose may not be enough. It is not clear whether the vaccine will be effective in seniors with an aging immune system. It is also unclear how long it will provide for protection.
–
The question also remains how many people will be willing to be vaccinated with the vaccine, which many believe was created in a hurry.
–
According to the BBC, more than two hundred different vaccines are currently being developed, but only dozens have entered the final third phase of clinical trials to confirm both efficacy and detect all rare side effects to be as safe as possible.
