That’s why you need the third dose: after 6 months the protection from infection drops to 50%

by admin

There is new data confirming the need to protect yourself with the third dose after 6 months. It is the one just published by the Higher Institute of Health where for the first time the effectiveness of the vaccine is recorded before and after 180 days from the injection. In fact, in the table developed by the ISS, the vaccine‘s shield against infection – that is, the possibility of getting infected – drops on average significantly after 6 months, that is to 50,2%, while before 6 months from the last dose the protection against infections is instead (always on average) del 75,7%.

Protection against severe forms remains high

The new data from the Higher Institute of Health reaffirms the need to carry out a third dose as early as 6 months after the last injection, especially to protect yourself from infection while the shield against the more serious forms that lead to hospitalization always remains high. . According to this new table, in fact, after 180 days, protection from infection (ie from contagion) drops to 50.2% (before 6 months it is on average 75.7%), but protection from “severe disease” remains high, that is from the risk of ending up in hospital, which always after 6 months is82,1% (before 6 months instead it is 91.8%).

The most significant decline is among the elderly

In short, the ISS data shows that there is a very sharp decline for infections, while it is more contained for the so-called “severe covid”, which brings together hospitalizations, intensive care and deaths. The decline can be seen in all age groups, but statistically it is more significant for the elderly, because we are still in a phase in which the vast majority of people vaccinated for more than 6 months (about 1.8 million), and the few who are not elderly are those who were vaccinated first: therefore they are either very fragile or belong to particular categories, such as health workers, who are more at risk of contagion. It is no coincidence that protection from contagion drops to 39.6% in the 60-79 age range and 41.9% between 40 and 59 years, while before 6 months the shield from infection is 71.9% for these two age groups.

The importance of the third dose

«The vaccine efficacy remains very high for hospitalizations, admissions to therapy and for deaths, it exceeds 90%, while for diagnosis, especially for the more central age groups it is a bit lower. It decreases significantly starting from the sixth month. This is why it is important to adhere, as six months pass, to the third dose according to the modalities recommended by the ministry “, confirmed Silvio Brusaferro, president of the Higher Institute of Health (Iss) in his speech at the usual press conference on the analysis of data from the Covid-19 monitoring of the Control Room. “There are millions of citizens – added Brusaferro – who have not even taken a dose, and it is extremely important that they start the cycle”.
