Booster and additional dose



As of July 18, administering a second booster dose is possible at your general practitioners and vaccination centres without registration. Registration for the second booster dose will be possible as of August 15.

Booster doses

In order to prolong the efficiency of the vaccination, it is recommended to get a booster dose after finishing the basic vaccination scheme.

The first booster dose (also called the "third dose") can be administered 4 months after a finished basic scheme.

If it has been another 4 or more months after the booster dose, you can get revaccinated by the second booster dose (or the "fourth dose"). The administration of the second booster dose is available as of July 18, 2022, according to the Ministry of Health's decision (Czech only).

First booster dose

The first booster dose can be administered

  • after at least 4 months since finishing the basic vaccination scheme (thus 4 months after the application of JCOVDEN (former Janssen) vaccine or the second dose in case of other vaccines),
  • to people who are older than 12,
  • to inhabitants insured in the Czech Republic on the costs of the health insurance companies,
  • with the Comirnaty and Spikevax vaccines (for minors between 12-17 only with Comirnaty),
  • at your general practitioners and vaccination centres without registration, or with registering through the Central booking system

In case you are entitled to get revaccinated by the booster dose, because 4 months since finishing the basic vaccination scheme have passed, you will receive a text message saying: 

CPOJ 32xx28xx22 se muze registrovat na posilujici davku ockovani proti Covid-19. Kontaktujte praktickeho lekare nebo se registrujte na crs.mzcr.cz.

(CPOJ 32xx28xx22 can now register for booster dose vaccination against Covid-19. Contact your GP or register on crs.mzcr.cz.)

If you decide to get revaccinated by your general practitioner, do not make a registration through the Central booking system.

You can find a list of vaccination centres that do not need registration here by clicking on the “Bez registrace a rezervace” (Without reservation or registration) filter.

The procedure of registering for the booster dose is the same like in case of the first dose. You can register here by clicking on "Registrace" (Registration). When registering through the Central booking system, it is necessary to use the same phone number that is saved in the ISIN system from the last entering of data (i.e. the last testing or vaccination). In case you come across any difficulties, contact Infoline 1221.

The certificates are generated in any case of booking, it does not matter whether you registered for the dose or not.

You can download the certificate here or in the Tečka app. If you cannot find your certificate or have troubles with signing in, contact Infoline 1221 or visit the support page of the Tečka app.

The certificate is valid right after administering the dose. As for now, according to the Regulation of the European Parliament and of the Council (EU 2021/953), its validity is not limited. However, in case of travelling, please verify your certification at the Ministry of Foreign Affairs since every country has its own altered entrance rules.

If you have used the JCOVDEN (former Janssen) vaccine during your basic scheme, the certificate will be marked as 2/1; if you used two doses during your basic scheme, the certificate will be marked as 3/3.

Self-payers: Self-payers will (pre)register at the registration for self-payers.

Second booster dose

The second booster dose can be administered

  • after at least 4 months since the first booster dose,
  • to people older than 18,
  • to inhabitants insured in the Czech Republic on the costs of the health insurance companies,
  • at your general practitioners and vaccination centres without registration, or with registering through the Central booking system

As of July 18, 2022, it is possible to get revaccinated by your general practitioner and at the vaccination centres without registration. The vaccination is recommended to people over 60 years old and people with a vulnerable hate state.

If you decide to get revaccinated by your general practitioner, do not make a registration through the Central booking system.

The revaccination by a second booster dose before the start of autumn is recommended to all people as part of the prevention of increased incidence of respiratory diseases.

Additional dose

Who can get revaccinated

People that suffer from:

  • moderate and severe immunosuppression,
  • moderate or severe primary immunodeficiency,
  • advanced or untreated HIV infection or
  • a condition requiring immunosuppressive therapy.

When you can get revaccinated

It is already possible to receive this dose provided that it is at least 4 weeks after finishing the basic immunization schedule i.e., at least 4 weeks after the first dose in case of Janssen vaccine or after the second dose in case of other vaccines.

How the revaccination looks like

This way of revaccination needs to be sufficiently substantiated by scientific results. You can get the additional dose only with a recommendation from a physician specializing in one of the above-mentioned conditions.

What you get revaccinated with

You will be revaccinated by mRNA vaccines i.e., Comirnaty vaccines (Pfizer/BioNTech) and Spikevax (Moderna). Other vaccines will not be used for
revaccination. A person that has been vaccinated for example with Vaxzevria vaccine (AstraZeneca), will be revaccinated with one of the mRNA vaccines as well.

Vaccination certificate validity

Vaccination certificate validity has not been altered i.e., the certificate is valid 14 days after the first dose in case of single-dose vaccine (Janssen) or the second dose in case of other vaccines. This validity is the same for the Tečka application. If you are going abroad, read up on the validity conditions in the given country, for example at Travelling.

In the Tečka application, you can also see the record of the additional dose.
