How long after being vaccinated doHow long after being vaccinated does an individual acquire protection against the virus?

The efficacy observed in clinical trials refers to a few days after the administration of the second dose. Therefore, maximum protection occurs after this period. Although, according to preliminary data from the ongoing campaign, some protection is also likely to occur after the first dose, this does not happen immediately following the inoculation of the vaccine, but develops progressively at least 7-14 days after the injection. The second dose of the vaccine, administered a certain number of weeks after the first dose, has the purpose of boosting that dose and prolonging its effects.
