Booster and additional dose



Preventive booster dose

Who can get revaccinated

Revaccination by the 3 rd dose is possible for people who have at least 6 months after receiving the first dose in case of single-dose vaccine (Janssen) or the second dose in case of other vaccines.

The age, job, or health status does not matter.

The booster dose is primarily recommended to people with immune disorders, chronic diseases, 60+ people, healthcare professionals and social workers.
However, the booster doses will also be available for anyone who wants to intensify their protection against Covid-19.

When you can get revaccinated

The revaccination with the booster dose is available from 20 September 2021, the dose is optional and paid for by your health insurance. On October 18, the period of 8 months after the second dose (or one dose of Janssen) has been changed to 6 months.

How the revaccination looks like

The day you reach 6 months after the last dose of your vaccination, you will receive a text message or e-mail 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.)

Administration of the booster dose (or more precisely getting to the place, where you will be vaccinated) can be done the following ways:

1. Registration at the vaccination center (through Central Reservation System)

Since 20 September, it is possible to register for revaccination. You can make your registration at REGISTRACE.MZCR.CZ and it has the same process
as with the previous doses. You type in your telephone number (the one you used for downloading the certificate or for registration before would be the best) and wait for PIN 1 sent in a text message. After its receiving, fill in
your personal details including your telephone number, health insurance number, name, and surname. The rest of your personal details are filled automatically in so called identification. The system knows you got vaccinated more than 8 months ago and can get your booster dose. Next you can choose a vaccination centre, finish the registration, and wait for PIN 2 that you will later use for logging into the reservation of your booster dose date (on REZERVACE.MZCR.CZ).

2. General practitioners

Since 20 September, it is possible to make an independent revaccination appointment with your GP.

3. Vaccination centres without registration

It is also possible to use such centres (you can find the complete list with the “Bez registrace a rezervace” (Without reservation or registration) filter on ockoreport.uzis.cz), where you get the booster dose if it is more than 8 months since receiving the Janssen vaccination or the 2 nd dose of other vaccines.

4. Telephonically on Infoline 1221

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.

People that received the first two doses of Comirnaty vaccine will be
revaccinated with Comirnaty vaccine once again.

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 on Dovolená 2021 (Holidays 2021).

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

Why to get vaccinated by the booster dose?

It has been proved that as the time progresses after the vaccination, there is a
graduate decrease in the effectiveness of the protection and therefore also
higher probability of getting infected. By this decrease of protection are mostly
and sooner at risk older people and people with immune disorders or chronic
diseases (typical also for other vaccinations). The booster dose significantly
increases the protection against getting infected more intensely and faster than
the previous doses.

Receiving the booster dose very quickly reinforces the protection even against
new coronavirus variants (such as the Delta variant) that have not been yet
known at the time of vaccinations development but are still spreading
worldwide. The antibody level is not equivalent to the vaccination protection.

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 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.
