Researchers brought together by the British Royal Society for this study warn that society must be “realistic” about what a vaccine will achieve and when it will happen.
Warning that it may take up to a year for the eventual vaccine to be distributed to the general population, the report “Development and implementation of the SARS-CoV-2 vaccine” clarifies that restrictions have to be “gradually relaxed”, rather than being completely removed as soon as vaccine distribution begins. At the moment, scientists around the world are developing more than two hundred vaccines against SARS-CoV-2. Still, there is no set date for the release of any of them.
Even when there is a vaccine available, it does not mean that in a month everyone will be vaccinated. We are talking about six months, nine months or maybe a year.”Explained Nilay Shah, from Imperial College London.
“It is not possible for life to suddenly return to normal in March,” he added, speaking to the BBC.
Immunologist Charles Bangham, also from Imperial College, explained in turn that “We just don’t know when a vaccine will be available, how effective it will be and, of course, how quickly it will be distributed.”.
“Even if it is effective, it is unlikely that we will be able to completely return to normality, so there will be an escalation (…). We will have to gradually relax some of the measures, ”he said.
“History full of failures”
The timing of vaccine distribution is therefore a “huge” challenge, according to the report. Nilay Shah estimates that vaccination of the population against Covid-19 should be carried out at a rate ten times faster than vaccination against the common flu, which would involve up to 30 thousand professionals involved.
“I am concerned that this issue is not being considered,” he admitted to the BBC.
The delay in the distribution of vaccines is not the only issue that worries specialists. The Royal Society Report Raises questions about the materials used in both the vaccines and the glass jars used to store them, but also regarding the cooling capacity of the vaccines, which must be kept at minus 80 degrees.
There is still uncertainty about the real effectiveness of the administration of this drug. “A vaccine offers great hope to end the pandemic, but we know that the history of vaccine development is fraught with failure.”warned researcher Fiona Culley, also from Imperial College.
Preliminary data from companies testing human vaccines against the new coronavirus say they trigger an immune response, but it is too early to determine whether that response offers complete protection.
