A successful vaccine for Covid-19 will not defeat the spread of the virus, a team of experts has said, but it still matters.
Hundreds of research teams around the world are working to develop a coronavirus vaccine, and 11 are currently in their third phase of human testing.
Professor Nilay Shah, head of the department of chemical engineering at Imperial College London, and one of the study's authors, said: "Even if vaccination starts in the spring, it will take a long time to work because it will be given priority. different groups and then we will reach the general population. ”
Professor Charles Bangham, chair of immunology at Imperial College London and a co-author of the study, said: "Even if [the vaccine] is effective, it is unlikely that we will be able to return to full normalcy."
Bangham stressed that few vaccines completely block an infection, but they can reduce the severity of the disease as well as the possibility of infections .
However, in the case of developing Covid-19 vaccines, there are many questions.
