Concerns about vaccines are nothing new. However, the pace of development of Covid-19 vaccine candidates has caused some people (understandably) to question how to quickly produce a safe and effective vaccine.
It usually takes about ten years to develop a new vaccine, but in less than a year, scientists seem to have made at least one vaccine for Covid. So how do they do it?
First, they are well-funded-time is money. Governments around the world desperate to get out of the crisis have invested billions of dollars to develop vaccines.
In such a short period of time, this is unprecedented. It may take several years for scientists to obtain funding for other vaccine research.
Since so many people are potentially vaccinated, safety must absolutely be the first priority. There is a very powerful international human test program that can determine the safety and effectiveness of any vaccine.
The World Health Organization (which is collating all data from trials of more than 200 vaccine candidates) says that safety data will not and will not be compromised.
Research will continue even after the vaccine is launched to track any rare possible side effects. In addition, much of the work needed to promote a successful vaccine to people around the world is already in progress. For example, hundreds of millions of the most promising vaccine candidates have been produced.
This usually only happens when the vaccine is approved for widespread use. If the vaccines are found to be ineffective or not safe enough after continuing to provide trial data, they will not be used. But if there is one-the vaccine will be deployed soon.
