Every week, nearly 300,000 people get an injection against COVID-19.

But, why do you still have to adhere to the corona measures after this injection and what do we now know about the side effects?

Eight questions about the consequences of a corona vaccine.

Do I still have to comply with the measures after vaccination?

Yes, at this point you must also adhere to all existing measures after vaccination.

So you have to put on a mouth mask in the supermarket and you are not allowed to throw a party with fellow vaccinees.

One of the reasons for this is that it takes time for the vaccines to work optimally.

Every vaccine approved so far consists of two injections.

The protection is only optimal after the second injection.

For the first two weeks after the first dose, the vaccine does not provide any protection at all.

After two injections, you must adhere to the measures, because there may still be a chance that you will infect others.

Research does indicate that the risk of becoming infectious after vaccination is much smaller than without vaccination.

In addition, the vaccines have been proven to protect against COVID-19, but none of the vaccines provide 100 percent protection.

Do I still have to get tested after vaccination?

For the reasons mentioned in the above question, you should, even if you have been vaccinated, have yourself tested if you have complaints that match COVID-19.

Only if you develop a fever or headache within 48 hours after vaccination you do not need to be tested.

You will probably suffer from the side effects of the vaccine.

If you suffer from shortness of breath in addition to a fever shortly after vaccination, a test is recommended.

How well does the vaccine work?

All approved corona vaccines protect against COVID-19.

Moderna and Pfizer vaccines prevent more than 90 percent of coronvirus infections with complaints.

AstraZeneca's vaccine prevents about 60 percent of COVID-19 cases with complaints.

These figures include both mild and more serious cases of COVID-19.

If you only look at severe COVID-19 or death from COVID-19, research indicates that the AstraZeneca vaccine offers good protection.

In Scotland, for example, it was found that a single dose of the AstraZeneca vaccine four weeks after vaccination was over 90 percent effective in preventing hospitalization.

The figures from one dose of the Pfizer vaccine were comparable.

What do we know about the side effects?

Regular side effects after vaccination are an aching arm, headache or temporary fatigue.

These side effects usually disappear within a few days.

There is no evidence that any of the corona vaccines cause serious side effects.

In rare cases, people can have a serious allergic reaction after vaccination, so everyone is monitored for 15 minutes after vaccination.

This means that any allergic reaction can be treated quickly.

Every two weeks, side effects center Lareb reports how many reports of side effects have been reported.

The known side effects, such as headaches, have been reported so far.

In addition, 87 deaths after vaccination have been reported.

The Lareb currently has no indications that serious side effects of the vaccination played a role in these deaths.

In the Netherlands, according to the Lareb, about 750-800 people die in nursing homes every week from all kinds of causes.

It is therefore to be expected that a number of elderly people who just happen to have been vaccinated will also die from something that has nothing to do with the vaccine.

To be sure, it is investigated whether there really is no connection.

How long does the vaccine work?

We know that the vaccines that have now been approved will provide protection against COVID-19 for at least several months.

This protection is expected to last a lot longer.

The reason we can't say how long the vaccines will work is that there aren't people who were vaccinated, say, a year ago.

Why is it still busy in hospitals, many elderly people have been vaccinated anyway?

The pressure on hospital care is still high.

The main reason that the vaccination campaign has little effect in the hospital can be seen in figures from the NICE foundation.

Most of the people who have been admitted to the intensive care unit were between 50 and 75 years old.

This group has barely been vaccinated.

So far, in addition to care workers, mainly people over 80 and nursing home residents have been vaccinated.

These people have a relatively high risk of dying if they get COVID-19.

However, Frits Rosendaal, professor of clinical epidemiology at the LUMC, previously explained to NU.nl that people from these groups are regularly not admitted to hospital if they get severe COVID-19, because the disadvantages of admission are sometimes greater than the possible benefits.

The risk of serious confusion or anxiety developing, for example, is greater during hospitalization.

Why will young people soon also receive a vaccine?

From May on, young people without a medical indication should also receive an invitation for vaccination.

What is actually the benefit of vaccinating this group?

Hans Heesterbeek, professor of theoretical epidemiology at Utrecht University, said earlier that one of the reasons for vaccinating young people is that we cannot predict precisely for whom COVID-19 will be mild and for whom severe.

"Of course there are risk groups and ages, that is clear. But there are also among the older elderly people who had little trouble and there are also serious cases among younger people," said Heesterbeek.

In addition, as long as the corona virus continues to circulate, new variants may also continue to emerge.

The risk of this is that variants will also emerge against which the vaccines offer much less protection, Rosendaal said earlier.

Are we already seeing the effects of vaccination?

The number of nursing home residents infected with the corona virus is decreasing.

In the over-80s living at home, the number of infections seems to stabilize and the number of deaths is decreasing, while the number of infections in 60 to 80-year-olds is actually increasing.

This is most likely an effect of vaccination.

Nursing home residents were among the first to be vaccinated and many over 80s have also had one shot.

Due to vaccinations in nursing homes, measures are now also slowly being relaxed.

Outgoing Minister Hugo de Jonge (Public Health) announced on Monday that if the residents in a nursing home are fully vaccinated, two people are allowed to visit each day instead of one.

A fully vaccinated resident of a nursing home also does not have to be quarantined as long if he or she has been in contact with someone with COVID-19.
