October 8th 2021 - When the first dose of the vaccine is administered, the risk of infection is the same as for unvaccinated persons because the immune system needs a few weeks to give rise to the response. The response then grows and protection over time increases until
it reaches its maximum about 15-28 days after the second dose. Vaccination therefore does not increase the risk of contracting the disease at any time.
