Vaccinations
Where do these figures come from?
RIVM delivers weekly data on the number of vaccine doses administered. This data is not currently available as an open data file.
The figures on coronadashboard.nl on the total vaccination coverage in the Netherlands (18 years and older / 12 years and older) come from a different source than the figures on the vaccination coverage per age group and the vaccination coverage per municipality.
The figures on the total vaccination coverage in the Netherlands are the figures that RIVM provides to the European Center for Disease Control (ECDC). These data are not yet available as an open data file.
The figures on vaccination coverage by age group are not yet available as an open data file.
The figures on vaccination coverage per municipality are available as an open data file.

How are these figures determined?
Vaccine doses administered
The number of doses administered is drawn from data that the municipal health services (GGDs) pass on to RIVM. RIVM records the number of doses administered by GGD vaccination centres, hospitals, healthcare institutions and general practitioners (GPs) in its central COVID Vaccination Information and Monitoring System (CIMS). However, the CIMS data is still incomplete, as GPs and institutions have not yet reported a small proportion of the doses that have been administered to RIVM.
Despite the incomplete data, we want to depict the number of vaccine doses administered and the number of people vaccinated as accurately as possible. To this end, the dashboard shows RIVM’s estimates of the number of vaccine doses administered in healthcare institutions and GP practices, and the number of people vaccinated. The estimates are based on the number of vaccine doses that have been delivered to the locations where injections are given.

Underneath the table showing the vaccination figures is a green bar. Click on ‘More information’ for a detailed explanation.
The calculated number of doses administered in general practices is currently unchanged, as the RIVM is recalculating this number. Once the calculation is complete, the number of doses administered in general practices will be updated.
Vaccination coverage
So far, RIVM bases its figures on the total national vaccination coverage on the calculated number of doses administered. This is because the reported vaccinations in the registration system CIMS were not complete enough earlier. As the vaccination coverage is partly based on calculations, the actual coverage may be slightly different.
The figures for vaccination coverage by age group and vaccination coverage per municipality come from CIMS. RIVM registers in CIMS how many people have started and how many people have completed the primary vaccination course.
A primary course has started when someone has had the first corona jab. A primary course is completed when someone has had the last necessary dose. Depending on the type of vaccine, this may be immediately after the first dose (Janssen vaccine), after the second dose (other vaccines) or after a corona infection and one dose (other than Janssen). If someone has had the last necessary dose, this person is fully vaccinated. Persons with a immune disorder are being offered a third dose. For this group, the third dose is part of the primary course of vaccines. These people also receive a booster.
On the dashboard we show how many people have had one shot and how many people have had the primary course of jabs. Third shots are not included in the booster vaccination rate.
We also show what percentage of all adults (18+) have received a booster jab. The booster turnout for the group aged 12 and older is shown as of 24 March 2022. A very high booster turnout in young people aged 12 to 17 is not a government goal. Young people will be offered a booster jab but the decision to get one is theirs (and/or their parents or guardians).
From 22 March 2022, we also show the number of repeat corona jabs. Repeat jabs are offered to groups of people (over-60's, people with a severe immune disorder, people with Down syndrome and people in care homes).
If the vaccination coverage is very high or very low in a certain population group, this can be traced back to individuals. For reasons of privacy, the dashboard in those cases therefore shows 'more than 95%' or 'less than 5%' instead of an exact percentage.
Vaccination coverage by age group and per municipality and number of fully vaccinated people actually higher
The vaccination coverage by age group and per municipality is in reality higher than shown on the dashboard. There are three reasons for this:
- General practitioners and institutions have not yet reported to CIMS a small proportion of the vaccinations they have carried out. The figures on the number of vaccinated people are therefore not complete.
- CIMS only lists the vaccinations given to people who have given permission to register their vaccination.
Waiting time after last vaccine dose
The dashboard counts someone as having had the primary course of corona jabs immediately after the last vaccine dose was administered. The dashboard therefore does not take into account the waiting time after the last dose. In the Netherlands, there is a waiting period of four weeks for the Janssen vaccine and a waiting period of two weeks for other vaccines. Only then does the vaccination provide sufficient protection against COVID-19 and does it count as a valid corona certificate.
Changes in the figures
Correction number of fully vaccinated people
From November 11, 2021, people who have had corona and one vaccine dose count as having completed the primary course of corona jabs in the 'Vaccinated people' graph. Until this date, they counted among not having completed the primary course.
Vaccination coverage
People who have had one shot after having had corona will also count as having completed the primary course from 22 September 2021 in the figures per municipality and per age group. As a result, these numbers have increased. In addition, a number of Janssen vaccinations that had been counted too much were removed from the data on the same date. As a result, the vaccination rate per age group has decreased somewhat.
Improved data
The GGD has removed appointments that were cancelled or that did not result in vaccination from its data set. It has also corrected the data for people who received doses of two different vaccines. Around 160,000 doses have been removed from the data set. The improved data set includes the data up to and including 8 August 2021. The figures on the dashboard were updated on 10 August 2021.
Administred vaccine doses
From 11 November 2021, it will no longer be possible to estimate how many vaccines have been administered for a first or second vaccination for vaccinations administered by providers other than the GGD (for example, institutions or hospitals). The reason for this is that the estimate of the number of administered first and second shots is based on the number of vaccines applied. With the spread vaccines, no distinction is made between the vaccines for the first and second shots and the vaccines used for the booster shot. It is therefore assumed that no more first and second shots will be administered by other providers as of 11 November 2021.
Where do these figures come from?
Data on deliveries and doses in stock is provided by the National Institute for Public Health and the Environment (RIVM). This is not yet available as an open data file.
How are these figures determined?
Deliveries
The ‘Deliveries’ graph on the dashboard shows the number of doses that the Netherlands has received and expects to receive. RIVM assumes that each vaccine vial contains a specific number of doses – BioNTech/Pfizer: 6.9 doses per vial; Moderna: 10 doses per vial; AstraZeneca: 11 doses per vial; and Janssen: 5 doses per vial. This may differ from the manufacturer’s instructions for some vaccines.
These figures include the vaccine doses for the Dutch Caribbean and the vaccine doses that the Netherlands donates to other countries.
Doses in stock per type of vaccine
In the graph ‘Doses in stock per type of vaccine,’ the dashboard shows the total and available stock per type of vaccine at the central storage site. The total stock covers stock that is available and stock that is not yet available. The stock that is not yet available comprises vaccines that still have to be checked.
The size of the stock fluctuates: shortly after a new delivery, the total stock of a vaccine is relatively high; just before the next delivery is released from quality control, the available stock is low.
These figures include the vaccine doses for the Dutch Caribbean and the vaccine doses that the Netherlands donates to other countries.
