Does the vaccine provide immediate and definitive protection against COVID-19, and can a vaccinated person still infect someone else?
Does the vaccine provide immediate and definitive protection against COVID-19, and can a vaccinated person still infect someone else?
Last update: 14/04/2021The risk of getting COVID-19 is much lower in people who have received the vaccine, but this vaccine – like any other vaccine – is not 100% effective.
Vaccines available today or under development reduce the severity of symptoms.
When a person receives a vaccine, they are not immediately protected. Vaccine efficacy is obtained 7 to 14 days after injection (2 doses for most vaccines, 1 dose for Johnson and Johnson).
Even vaccinated, you could be infected without knowing it and transmit the virus to relatives. Wearing a mask therefore remains necessary.
