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.
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.
Vaccination is not compulsory in Switzerland. However, we recommend getting vaccinated. Vaccination offers good individual protection and helps contain the pandemic.
The authorities in your canton can tell you when and where you can get vaccinated.
(daily 6 a.m. to 11 p.m.)
The Covid-19 vaccination is free of charge for you.
For complete vaccination protection, you need to be vaccinated twice with an interval of three to four weeks.
Vaccination is also recommended if you have already been infected with the new coronavirus. One dose of the vaccine is sufficient in this case. You do not need to get a second dose. Exceptions apply for people at particular risk. Consult your doctor for more information. It is generally also possible to have two doses of the vaccine after a coronavirus infection.
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:
- Children under 12 years
The Federal Office of Public Health does not recommend the general vaccination of pregnant women for the time being. However, in the case of certain forms of chronic illness or an increased risk of infection (e.g. healthcare workers), vaccination with an mRNA vaccine is possible. If you are pregnant, please discuss your options with your doctor.
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.
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.
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.
Protection begins about two weeks after the first dose and is complete one week after the second dose – or 14 days after the first vaccination with the Johnson & Johnson vaccine as this is administered in a single dose.
You don't yet know. At the moment, manufacturers are investigating how long the vaccination protects. Current data show that protection from getting the disease lasts for at least 12 months. It may be that after a certain period of time another vaccination has to be given.
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.
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.
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».
No. You will not get Covid-19 as a result of the vaccination. There are no corona viruses in the vaccine.
If you have already contracted the new coronavirus, vaccination is recommended by six months after the infection. From 4 weeks after a confirmed coronavirus infection, one dose of vaccine is sufficient. 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.
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.
So far, the federal government has signed contracts with the vaccine manufacturers Pfizer/BioNTech, Moderna, AstraZeneca, Novavax and Curevac. 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 Covid-19 vaccine “COVID-19 Vaccine Janssen” from Johnson & Johnson was approved on 22 March 2021. The AstraZeneca vaccine is in the approval process at Swissmedic.
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.
The Johnson & Johnson vaccine is based on an adenovirus (harmless human cold virus), which contains the blueprint for the spike proteins of the coronavirus SARS-CoV-2 and introduces it into the body. This blueprint enables the body’s own cells to produce the protein that is unique to the COVID-19 virus. The human immune system recognises that this protein is foreign and reacts by establishing natural defences against a COVID-19 infection. The adenovirus in the vaccine cannot multiply and does not cause illness.
The video from Swissmedic explains how the viral vector vaccine works.
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 approved for anyone aged 12 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.
The “COVID-19 Vaccine Janssen” from Johnson & Johnson is a viral vector vaccine and is administered just once (single dose). The data shows an efficacy of between 64.2% (age group 18 to 64) and 82.4% (aged 65 and over) in all investigated age groups 14 days after the vaccine. The vaccine can be stored frozen at -25°C to -15°C and transported chilled or thawed at 2°C to 8°C. Once removed from the freezer, the unopened vaccine can be stored in a refrigerator for up to 3 months.
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.
No. The Comirnaty® vaccine from Pfizer/BioNTech is stored at -75°C– that from Moderna at -20°C and that from Johnson & Johnson at -25°C to -15°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.
