“99% of Italians need to be vaccinated to not use the green pass” – Corriere.it


from Cristina Marrone

Herd immunity is out of reach. Expert: Green certification is a public health measure to limit as much as possible the transmission of the virus in community places, including offices.

The mandatory health and after-school green transition will also be extended to public employees and will not be excluded from decision-making for private individuals. is it really necessary?

I would say yes, given that the share of unvaccinated subjects in the young population is still quite significant. Paolo Bonanni, epidemiologist, full professor of Hygiene at the University of Florence. green pass, a person vaccine or there isnegative swab in the last 48 hours. We know that we certainly cannot exclude that a vaccine is not positive, but transmission is much less likely. We also know that those with negative swabs can become infected in the hours following the test, but it is assumed that the amount of virus in the respiratory tract is not enough to infect others. The green pass is then a ensure that only people with these requirements can access community sites

Places where you usually stay for long periods of time, such as offices, where transmission is easier because they are closed.

What is the scientific purpose of the green transition?

Aim reduce the chain of spread of the virus as much as possible, limit deaths as much as possible and avoid saturating hospitals and intensive care units: this way doctors can return to deal with many other health emergencies that have been in the background in the past year and a half. We have found that the vaccine is very effective in preventing serious diseases: by limiting its spread, fewer and fewer people will be hospitalized.

When will it be possible to say goodbye to the green gate?

If 99% of the working population were vaccinated, it probably wouldn’t be enough to claim a cost-benefit green pass, but we’re not in that situation yet.

Should we achieve herd immunity?

Famous 80% of the vaccinated population no longer sufficient to achieve herd immunity because variant

Very contagious delta
, (Cdc estimated that a positive person could infect 8-9), e vaccines are not 100% effective
, especially in infections: means that transmissions are possible even between vaccinated persons. L’herd immunity unattainable because in theory 100% of the population should be vaccinated and this is not possible with those already exempted for medical reasons. Instead, we will have to learn to live with the virus. We can set ourselves a pandemic control target, but the virus is unlikely to go extinct as it evolves and changes.

Wouldn’t it be more beneficial to apply the green pass only to the population over 50 who are at risk of serious illness?

A green pass is asked of a person whom the state wishes to protect from serious illness or death. public health measure because the individual is free to refuse to accept a treatment, and this is not just for Covid: freedom of choice is inviolable in this respect. We justify the green transition by the fact that it is necessary to prevent the spread of infection in the community. and is currently the youngest with greater social backgrounds leading the contagion.

Why did Italy initiate the green transition and why did the UK withdraw?

There are countries that do not need these tools because they have a greater cultural-scientific maturity. While the British did not allow the state to make individual choices, on the other hand, they did not allow themselves to be begged when faced with the possibility of vaccination, and today they are among the most vaccinated in Europe.
