The number of reports of disease cases that fall within the national vaccination program

The National Vaccination Program (RVP) Monitoring Report describes how things are going in the Netherlands with 12 infectious diseases against which the National Vaccination Program vaccinates.

In 2021, fewer people will have a disease against which they are vaccinated under the National Immunization Program (RVP) than before the COVID-19 pandemic. Most likely, this is largely due to corona measures, such as keeping your distance and washing your hands.

Surveillance data and scientific developments
The National Vaccination Program (RVP) Monitoring Report describes how things are going in the Netherlands with 12 infectious diseases against which the vaccine is vaccinated. The report examines how severe diseases are and how effective vaccines are. This is done, for example, by looking at how many people have fallen ill and how often someone has had to go to hospital. The report also compares these figures with the same numbers from previous years and from other countries.

The report also contains information about communicable diseases that are not yet included in the NIP, such as rotavirus.

The number of patients is less than it was before the Corona pandemic
Reports of pertussis, mumps and acute pneumococcal disease have decreased in particular. The number of reports of meningococcal disease type W decreased further after this vaccination was added to the NIP in 2018.

Measles was not reported once last year, while there are still 84 reports in 2019. Furthermore, there have been no reports of rubella and polio. There were also no reports of diphtheria and tetanus in 2021.

There were fewer cases of acute hepatitis B in 2021 than in 2020: 72 cases in 2021, 95 in 2020. The number of reports of chronic hepatitis B was about the same in 2020, but compared to 2019 it is down The number is about a third. There’s a good chance that fewer people will have chronic hepatitis C. This decrease may be due to the fact that people have visited the doctor less due to the Corona pandemic.
The only exception in which the number of reports has not decreased is severe illness due to Haemophilus influenzae type b (Haemophilus influenzae type b). This is a bacterium that is present in the nasal cavity of almost all people. In 2020 and 2021, HCV was reported 68 times, while in 2019 there were only 39 cases. The RIVM is investigating why this is. The vaccine appears to work as before.

Low national vaccination coverage
The vaccination rate has decreased slightly compared to last year. This is a decrease of 1 to 2 percentage points. The percentage of immunizations in vaccinations given before the age of two is between 92% and 93%.

The decrease is partly because some vaccinations were given later than usual due to the coronavirus pandemic. If the decrease persists, an investigation into the cause should be carried out. Based on these findings, measures can be taken.

Changes to RVP
Since February 2022, girls and boys are invited to be vaccinated against human papillomavirus (HPV), and the HPV vaccination is given in the year children turn 10. A catch-up campaign has also been launched for boys and girls under the age of 18 who are not (fully) vaccinated against HPV.

Rotavirus vaccination and influenza vaccine for pregnant women
In 2021, the Board of Health advised that all young children be vaccinated against rotavirus and called for more high-risk groups to be vaccinated against influenza, including pregnant women. The Ministry of Health, Welfare and Sport (Ministry of Health, Welfare and Sport) has adopted both recommendations and preparations for their implementation are underway.

Since last year, a chapter on Corona has been added to the Red Sea cruiser monitoring report. The most important point from this chapter is that corona vaccines work well against serious diseases, and therefore against hospitalizations and deaths. Vaccinated people who get sick are less contagious than unvaccinated people. Protection decreases slowly after vaccination, but is restored by booster and repeat vaccinations.
