  • Covid Nine times more hospitalizations than last summer despite the vaccine

  • Coronavirus How many vaccines have been given in Spain?

    This is how vaccination against Covid-19 advances in each community

It is the most recent report, the most up-to-date made in Italy. It measures more and more reliably the impact of

vaccines

on the course of

Covid infections

in parallel with the progress of the campaign that extends immunization to larger and larger sectors of the population. The period examined by the

Italian Higher Institute of Health, in

charge of the report, includes the last 30 days. This is a more accurate snapshot because the number of vaccinated is now on the order of several million and allows reflections on the difference between who is vaccinated and who is not yet.

The first effect is the

global efficacy of the vaccine,

which "is greater than

70%

in preventing infection in vaccinated with

incomplete

cycle

" and "greater than

88%

for vaccinated with

complete

cycle

".

The effectiveness in

preventing hospitalization

amounts to "80.8% with incomplete cycle" and "94.6% with complete cycle".

While "in the

prevention of admission to intensive care it

is 88.1% with incomplete cycle and 97.3% with complete cycle".

About the

deaths

,

the slide is encouraging: "The effectiveness is 79% with incomplete cycle and 95.8% with complete cycle."

With a methodological note: these are estimates that do not take into account factors that could influence the assessment, such as the presence of "comorbidities" in infected subjects, that is, with pathologies that could multiply the risk.

The range of 12 to 39 years

This is the age group that started about a month ago with the administration of the vaccine in Italy.

Now it has entered the heart of the campaign.

It has an almost irrelevant Covid lethality index, but it has greater mobility and, therefore, greater capacity for the virus to transmit.

The

88.4% of infections

in the last month and in this age group occurred in

unvaccinated subjects

.

8.1% of the cases had been covered with one dose.

3.4% with two doses.

97.2% of hospitalizations correspond to people without coverage and only 0.8% of those who have completed the vaccination cycle.

There were zero deaths for those who were vaccinated, while 87.5% of adverse events were recorded among those who were not vaccinated.

The range of 40 to 59 years

In this age group there are similar differences between those who are not vaccinated and those who are.

71.3% of

Covid

cases

this last month, reports the ISS, refer to subjects

without vaccination coverage

, 19.7% had received a dose, only 9% had completed the vaccination cycle.

In this age group, there was zero risk of vaccinated people ending up in intensive care.

There are no reported cases because

95.7% of those who needed oxygen were not vaccinated

.

Even in similar proportions of deaths: 90% were not vaccinated, only 2% had received both doses and 8% only one.

The range of 60 to 79 years

In this range, the lethality of

Covid

is more relevant.

In the last month the proportions have shifted, tipping the balance largely on the side of the vaccinated.

47.7% of the new cases were not vaccinated, while only 18.2% had completed the vaccination cycle.

Of those who ended up in

intensive care, 71.2% had no coverage

, with a double dose the percentage dropped to 3%, to 25.8% with a single dose.

73.1% of the deceased were not vaccinated, only 5.6% had completed their course.

Over 80

Also in this range there is a substantial difference between vaccinated and unvaccinated.

Among those hospitalized, the gap shortens only for ordinary hospitalizations: 49.9% of hospitalized patients were not vaccinated compared to 42.1% who were.

But 80.8% of those who ended up in the ICU on ventilation had not received the vaccine and only 19.2% had received the full two-dose cycle.

Deaths also affect those who did not want to be vaccinated by 65.9%.
