As of today, people will need to prove that they are two weeks after the second dose of vaccine (or one dose of the Janssen vaccine) to be considered vaccinated. It is no longer sufficient to show 22 days from the first dose of vaccination to prove that you are not capable of transmitting Covid-19, which is needed to visit some services or mass events. In such a case, it will be necessary to submit a negative test. Insurance covers four antigen tests a month, which proves non-infectiveness for three days, and two PCR tests a month, which are valid for seven days. The government has tightened conditions due to the risk of spreading the Delta variant, against which a single dose of vaccine is less effective. People should show proof when entering mass events in culture or sports, when visiting a theater, or when using certain services such as accommodation, swimming pools, hairdressing, or wellness. People should also prove themselves at the inspection when visiting a restaurant, but the operators do not have to check the certificates. According to Health Minister Adam Vojtěch, however, a change is being considered.
