COVID-19 Vaccine Janssen is intended for all vaccine-eligible people ages 18 years or older to protect against coronavirus infection (COVID-19).
Currently, this vaccine is used in Lithuania only as a booster, i.e., it can be given to people who have already received Janssen COVID-19 Vaccine for the primary series. This decision is based on the fact that one dose of COVID-19 Vaccine Janssen is less effective compared to the other vaccines used.
Janssen COVID-19 vaccine is produced from another virus in the adenovirus family that has been modified to contain a gene encoding the SARS-CoV-2 spike protein. The vaccine does not contain the virus itself and cannot cause COVID-19 disease.
For more information about the vaccine, see the product sheets that include the package leaflet.
