Kovid: Vaccine ‘will not return to normal life in spring’

Even an effective coronavirus vaccine will not return life to normal in the spring, a group of leading scientists has warned.

A vaccine is often seen as a sacred grave that will end the epidemic.

But a report by researchers brought together by the Royal Society says that we need to be “realistic” about what and when vaccines can be acquired.

He said the restrictions may need to be “slowly relaxed” as the vaccine may take up to a year to roll out.

More than 200 vaccines to protect against viruses are being developed by scientists around the world in a process that is happening at an unprecedented speed.

Dr. of the National Heart and Lung Institute of Imperial College London. “A vaccine potentially offers a lot of hope to end the epidemic, but we know that there are a lot of failures in the development of the vaccine,” said Fiona Kully.

There is optimism, including from UK government scientific advisors, that some people may get a vaccine this year and mass vaccination may begin early next year.

However, the Royal Society report warned that it would be a long process.

Professor Nilay Shah, Head of Chemical Engineering, Imperial said, “Even when the vaccine is available, it does not mean that everyone is going to get vaccinated within a month, we are six months, nine months … about a year. I am talking about. ” College London.

“There is no question of suddenly returning to life in March.”

The report noted that there are still “enormous” challenges.

Some experimental methods – such as RNA vaccines – have never been mass-produced before.

There are questions around the raw materials – for both vaccines and glass vials – and the capacity of the refrigerator, with some vaccines requiring storage at minus 80C.

Prof Shah estimates that vaccinated people will have to take place 10 times faster than the annual flu campaign and work full-time for 30,000 trained employees.

“I worry, is there enough thinking going on throughout the system?” He says.

Preliminary trial data have suggested that the vaccines are triggering an immune response, but studies have not yet shown whether this is sufficient to provide complete protection or reduce the symptoms of covariates.

Unanswered questions

Professor Charles Bangum, chair of immunology at Imperial College London, said: “We do not easily know when an effective vaccine will be available, how effective it will be and of course, how quickly it can be delivered.

“Even if it’s effective, it’s unlikely that we’ll be able to be completely normal, so there’s going to be a sliding scale, even after the introduction of a vaccine Which we know to be effective.

“We have to slowly relax with some other interventions.”

And many questions that will determine the vaccination strategy remain unanswered:

  • Will one shot be enough or will booster be required?
  • Will the vaccine work adequately in older people with impaired immune systems?

Researchers have warned on the issue of long-term immunity that it will still take some time to respond, and we still do not know if people need to be vaccinated every two years or if there will be a shot.

Commenting on the study, Dr. of the University of Bath. Andrew Preston said: “Clearly the vaccine is depicted as a silver bullet and will ultimately be our salvation, but it may not be an immediate process.”

He said that there is a need to discuss whether a “vaccine passport” is needed to ensure vaccination of people coming into the country.

And Dr. Preston warned that the vaccine hesitation appears to be a growing problem that has become entangled in anti-mask, anti-lockdown ideologies.

“If people refuse to vaccinate cohabiting people, do we leave them to fend for themselves or do children have to go to schools or have mandatory vaccinations for staff in care homes?” There are a lot of difficult questions. ”
