Why do people who have been vaccinated and received two doses also have to stay at home if they live in the red areas?
Even when protected by the vaccine, the possibility of becoming infected is not completely excluded. All vaccines, not just anti-Covid vaccines, are not a 100% shield. Immunity reaches up to a certain percentage (in the case of AstraZeneca, Pfizer and Moderna preparations it ranges from 70 to 95%) and much depends on the individual response which can be more or less ready. Some do not react optimally.

Does it apply to all infectious disease vaccines?
Even those who take the flu, which among other things have lower coverage than anti-Covid, do not shy away from the probability of catching the infection.

So whoever has completed the inoculation cycle must behave like everyone else?
He must stay at home and respect the travel limits imposed in the various Regions, wear a mask and take care of hand hygiene. These are new drugs, the vaccination campaigns started a few weeks ago, the number of people who received the doses is still too limited to draw definitive conclusions. Therefore it is good to observe the rules and consider yourself potentially exposed in order not to risk being infected by the virus. With high probability we will not get sick, but we may develop an asymptomatic form which passes Sars-CoV-2 to others.

How long does the protection last?
We do not know, we will see it over time. Many vaccines need a more or less close booster.
–
Will there come a time when the vaccinated, on the strength of an ideal patent, will be able to feel free, as in Israel?
Of course it will. When we reach a certain percentage of the vaccinated population, up to herd immunity, the virus will circulate less and then the constraints can be dropped. Not now, with the epidemic peaking, the incidence high, the hospitals under pressure again, the Rt replication index above unity. The return to normal life will not happen suddenly.

the fault of the variants?
Also. Data on the protection of vaccines from mutated strains are not sufficient. They seem to defend against the more severe forms of the disease and well to do them.
