Do you have any questions about Covid-19 vaccination? Here you can find out why you should be vaccinated, how the vaccination works, how long the vaccination protection lasts, which side effects can occur in rare cases and which vaccines are already in use.

Who should vaccinate when, where, why and how often

Why should I get vaccinated?

A vaccination against Covid-19 will help protect you and contain the pandemic. The virus is very contagious. Some of those infected suffer from a severe course of the disease. People aged 65 and over, pregnant women and adults with previous illnesses are particularly at risk. In addition to the rules of conduct and hygiene, vaccination is the most effective means to date to reduce the number of serious illnesses and deaths in Switzerland. Only when around 70 % of the population are immune will the transmission of SARS-CoV-2 be reduced to such an extent that this pandemic will pass.

Do I have to get vaccinated?

Vaccination is not compulsory in Switzerland. However, we recommend getting vaccinated. Vaccination offers good individual protection and helps contain the pandemic.

When and where can I get vaccinated?

The authorities in your canton can tell you when and where you can get vaccinated. The vaccination doses are only available in limited numbers at the beginning. People who are particularly at risk therefore have top priority. All others are asked to be patient. 

What does the vaccination cost?

The Covid-19 vaccination is free of charge for you.

How often do I have to get vaccinated?

For complete vaccination protection, you need to be vaccinated twice with an interval of three to four weeks.

Who shouldn't get vaccinated?

The only contraindication to the vaccination is in people with a severe, confirmed allergy to any component of the vaccine (especially PEG).

The Covid-19 vaccination is currently not recommended for the following people:

  • Pregnant women
  • Children and adolescents under 16 years

If you have a high fever, feel sick or unwell, are waiting for your Covid-19 test result, are in isolation or quarantine, do not get the vaccination. Get the vaccination as soon as possible.

Vaccination protection

Is the vaccination effective and safe?

Every vaccine needs approval and a recommendation in Switzerland. To do this, it must meet high standards for safety, effectiveness and quality. The Swiss Agency for Therapeutic Products, Swissmedic, carefully examined and approved the vaccine against Covid-19. It is safe and it works. Tens of thousands of people have already received the vaccine in medical studies. It is also safe and effective for the elderly and those with chronic diseases. Swissmedic continues to monitor the safety and effectiveness of the vaccine. In general: The risk of serious side effects after vaccination is much smaller than the risk of serious disease progression after infection with the coronavirus.

How does vaccination protect?

Ihr Körper baut einen Schutz gegen Covid-19 auf. Die Impfung stärkt Ihre Abwehrkräfte und hilft Ihrem Körper, gegen das Virus zu kämpfen. Die Impfung senkt das Risiko, dass Sie Covid-19 bekommen erheblich. Einen vollständigen Schutz gibt es jedoch nicht. Einige Menschen können trotz der Impfung Covid-19 bekommen. Mit der Impfung ist die Chance jedoch höher, dass sie nicht schwer krank werden.

How long will it take to be protected after vaccination?

Protection begins about two weeks after the first dose and is complete (95 %) one week after the second dose. 

How long does the vaccination last?

You don't yet know. At the moment, manufacturers are investigating how long the vaccination protects. It may be that after a certain period of time another vaccination has to be given.

What side effects can the Covid vaccination cause?

A distinction must be made here between harmless, temporary vaccination reactions and real serious side effects. Vaccine reactions are common and go away within a few days. Possible vaccine reactions are pain at the area of injection, tiredness, headache or body aches or high temperature. They show that the body is building up the vaccine protection and are therefore a good sign in mild form. Very rarely are there serious side effects such as a severe allergic reaction right after vaccination. An allergic reaction may cause swelling, redness, itching, or difficulty breathing. If you experience such symptoms, contact your doctor immediately.

How long can side effects last?

The side effects usually go away after a few days. If after a week you still have any side effects or they get worse, speak with your doctor.

Could serious side effects still occur years later?

More than two million people have now been vaccinated. Severe anaphylactic reactions - these are severe allergic reactions - have only been reported in the single digits. Affected were patients with known severe anaphylaxis. Other serious side effects discussed in previous vaccinations, such as paralysis, have not yet been attributed to the Covid vaccinations. In addition, a serious autoimmunological reaction to a real infection or to a vaccination never occurs after years, but if so, then in the first one to a maximum of three months after the immunological «stimulus».

Vaccination and Covid-19

Can I get Covid-19 from the vaccination?

No. You will not get Covid-19 as a result of the vaccination. There are no corona viruses in the vaccine.

Can I get vaccinated if I already have Covid-19?

The exact duration of protection after illness with Covid-19 cannot yet be conclusively answered. Data indicates that you are protected from re-infection for at least three months. If you have already contracted the new coronavirus, vaccination is therefore only recommended three months after the illness. With the vaccination you receive optimum protection and the immune defence is additionally strengthened. If the infection has gone unnoticed, a vaccination is not harmful. 

Can I infect other people with Covid-19 even if I have been vaccinated?

The vaccination protects you from the consequences of a serious Covid 19 disease. However, it is not yet known whether the vaccination will prevent infection. So it could be that you still infect other people despite the vaccination and without showing symptoms. You should therefore continue to adhere to the rules of hygiene and behaviour.

I recently had another vaccination or another vaccination is due (e.g. against influenza). Is that a problem with the Covid vaccination?

There is no reason to believe that there could be an interaction between the Covid vaccine and other vaccines. Vaccinations protect you from infections that can also endanger or harm you during the pandemic. However, there should be a minimum of 14 days between vaccinations. This does not apply to emergency vaccinations.

Vaccines

What types of vaccines are available?

So far, the federal government has signed contracts with the vaccine manufacturers Pfizer / BioNTech, Moderna and AstraZeneca. The Comirnaty® vaccine from Pfizer / BioNTech received approval from Swissmedic on 19 December 2020. Moderna's vaccine (COVID-19 mRNA Vaccine Moderna) was approved by Swissmedic on 12 January 2021. The AstraZeneca vaccine is in the approval process at Swissmedic.

How do Pfizer / BioNTech and Moderna vaccines work?

Pfizer / BioNTech and Moderna's mRNA vaccine contains genetic information of the novel coronavirus. From this tiny piece of blueprint, the body creates a small part of the virus - the so-called spike protein. The immune system recognises this as foreign and forms antibodies against it. The immune response has started. Both the mRNA blueprint and the spikes are broken down within days. This active immunisation prevents the SARS-CoV-2 viruses from penetrating human cells and multiplying.

This video from Swissmedic explains how the mRNA vaccine works.

What are the differences between Pfizer / BioNTech and Moderna vaccines?

Both preparations are highly effective. The vaccine developed by Pfizer / BioNTech offers around 95 percent protection against Covid-19. At Moderna, an overall effectiveness of 94.1 percent is stated.

While Comirnaty® gives 30 micrograms of vaccine per injection, Moderna's mRNA-1273 has 100 micrograms. The Pfizer / BioNTech vaccine is suitable for anyone aged 16 and over. The Moderna vaccine differs from this with its suitability for all people aged 18 and over. The two vaccines contain different additives.

Otherwise, the two vaccines are similar. Both vaccines are mRNA vaccines and are well tolerated. Both Pfizer / BioNtech's Comirnaty® and the Moderna preparation require two doses for the vaccine to develop its full effect. These should be administered about four weeks apart. The second vaccination must be given with the same vaccine as the first.

Can the new mRNA vaccine change my genetic material (DNA / genes)?

The mRNA vaccine is not transported into the cell nucleus and cannot affect the human genome. The vaccine contains mRNA, which codes for the formation of a specific protein that forms the spike-like projections (spikes) on the SARS-CoV-2 virus wall. This protein serves as an antigen, is recognised by the body as foreign and thus stimulates the body's own immune system to react against the spikes of the SARS-CoV-2 virus. Antibodies are formed which are responsible for protecting against the virus.

Will the vaccine be injected into my body at -75 ° C?

No. The Comirnaty® vaccine from Pfizer / BioNTech is stored at -75° C - that from Moderna at -20° C - but shortly before vaccination it is thawed and absorbed in saline, which is stored at normal refrigerator or room temperature.

All interim results on the effectiveness and safety of the vaccines can be found on the Infovac website.
