Coronavirus vaccine “may never appear” and blockages could become the norm, warns expert


A coronavirus vaccine may never be created and blockages may become the norm, warned an expert.

Dr. David Nabarro, a professor at Imperial College London, warned that we should not make absolute assumptions about a vaccine, adding that such a risk may not appear at all.

Speaking to CNN, Dr. Nabarro explained, “There are certain viruses against which we still do not have vaccines.

“We cannot make the absolute assumption that a vaccine will appear at all, or if it appears, if it will pass all efficacy and safety tests.

“It is absolutely essential that all societies around the world put themselves in a position where they are able to defend themselves against the coronavirus as a constant threat, and to be able to devote themselves to social life and economic activity with the virus among us. “

Several teams around the world – including one at the University of Oxford – are working to develop a vaccine against coronaviruses.

However, Dr. Nabarro added that there is no certainty that any of these vaccines will work for the general public.

He said, “You have high hopes, then your hopes are dashed.

“We are dealing with biological systems, we are not dealing with mechanical systems. It really depends on how the body reacts. ”

Dr Nabarro’s warnings come soon after the University of Oxford has teamed up with pharmaceutical giant AstraZenenca for the development, manufacturing and large-scale distribution of the candidate vaccine Covid-19 currently being tested in the UK.

The move will allow rapid vaccination worldwide if the candidate proves effective, the university said.

Human trials of the vaccine developed by the university’s Jenner Institute began last week, with hundreds of people volunteering to participate in the study which received £ 20 million in government funding.

Professor Sir John Bell, Regius Professor of Medicine at the University of Oxford, has described the partnership with AstraZeneca as “a major force in the fight against pandemics” for the foreseeable future.
