Covid-19: The vaccine will not immediately restore normalcy

Even an effective vaccine against Covid-19 will not bring life back to normal in the spring, a team of top scientists has warned.

A vaccine is often considered the holy grail that will end a pandemic.

However, a report by Royal Society researchers said that we need to be "realistic" about what a vaccine could achieve and when.

They said the restrictions could be "gradually relaxed", as it could take up to a year for the vaccine to be released to the public.

More than 200 vaccines are being developed by scientists around the world in a process that is taking place with unprecedented speed.

"A vaccine offers great hope for an end to the pandemic, but we know that the history of vaccine development is fraught with many failures," said Dr. Fiona Culley, of Imperial College of London.

The British government's scientific advisers are optimistic that part of it population may be vaccinated this year and mass vaccination may begin early next year.

However, the Royal Society report warns that it will be a long process.

"Even when the vaccine becomes available, it does not mean that all the vaccine will be vaccinated within a month. population. This process can take up to a year, "said Professor Nilay Shah, head of Imperial College London.

"There is no way our lives can suddenly return to normal in March."

The report said there were still "huge" challenges ahead.

Some of the experimental approaches taken - such as RNA vaccines - have never been mass-produced before.

There are questions about the raw materials - both the vaccine and the glass vials - and the capacity of the refrigerators, as some vaccines are needed Save at minus 80 degrees Celsius.

Shah estimates that the population should be vaccinated at a rate 10 times faster than the annual campaign seasonal flu and will be full-time employment for 30.000 people.

The data of the first trial showed that the vaccines elicit an immune response, but studies have not yet shown whether this is sufficient to provide a complete protection or reduce the symptoms of Covid-19.

Unanswered questions

Professor Charles Bangham, president of Imperial College Immunology, said: "We do not know when a vaccine will be available, how effective it will be and, of course, how quickly it can be delivered.

"Even if it is effective, it is unlikely that we will be able to fully return to normalcy."

Many questions that will dictate the vaccination strategy against Covid-19 remain unanswered, such as:

Will one vaccination be enough or will more doses be needed?

Will the vaccine work well in the elderly with a severe immune system?

Researchers warn that the issue of long-term immunity will take some time to answer, and we still do not know if humans will need to be vaccinated every two years or if a vaccine will be given.

Commenting on the study, Dr Andrew Preston of the University of Bath said: "It is clear that the vaccine has been portrayed as our salvation, but it may not be an immediate process."

He also said that there should be a discussion on whether "vaccine passports" are needed to ensure that people entering a country are vaccinated.

Dr. Preston warned that hesitation about vaccines seems to be a growing problem that falls under the same ideologies as opposing mask use and exclusion.

"If there are groups of people who refuse to get the vaccine, we let them keep that choice or carry out compulsory vaccination for children who go to schools or for staff in care centers? There are many difficult questions that need to be answered. "
