Your head aches, your limbs ache and your temperature is rising – these are typical flu symptoms. Many people have mixed feelings about the flu vaccine. Comparis explains the pros and cons of getting the flu vaccine.
It's the same story every autumn – should you get the flu vaccine or not?
This uncertainty is what leads many to put the decision on hold or wait until the ideal time to get vaccinated (mid-October till mid-November, but can be later) has passed.
Between October and April, the Federal Office of Public Health (FOPH) provides weekly reports on the status of flu-like illnesses in Switzerland (in German, French and Italian only). This ensures that the general population as well as doctors are informed of any flu outbreaks in good time. If the number of suspected flu cases reaches 69 per 100,000 inhabitants, this is considered a flu epidemic.
According to the FOPH, around 1.21 million vaccine doses are available in Switzerland for the 2019/2020 flu season. This number is comparable with the quantity produced in recent years. The largest number of vaccine doses were supplied in 2006 (1.39 million). Since then, the figures have not fluctuated significantly.
The problem is that vaccine sceptics endanger not only themselves, but others too. Many of those infected don't notice that they are ill or think they just have a slight cold. By continuing to use public transport, going to work or to the cinema, they unknowingly spread the virus – including to at-risk groups such as pregnant women or the elderly.

The following people should be vaccinated against flu:
A flu vaccine generally provides protection for about four to six months. You should therefore be vaccinated once a year to cover you for the flu season during the winter months. However, flu viruses are constantly changing and therefore vary from season to season. This is why the vaccine has to be modified for each flu season.
Vaccines protect – even if not 100%. But why are so many reluctant to get the flu vaccine? For one thing, the protection it offers is limited. While the measles vaccine is almost 100% effective at preventing an outbreak of the disease, the flu vaccine is only around 60% effective. This is because the flu virus has time to mutate after the vaccine is manufactured in February. If it does, this will affect rates of effectiveness. What's more, not all flu vaccines protect against the latest viruses.
Possible side-effects are another negative aspect:
Severe side effects are extremely rare and many times rarer than the risk of serious complications from the flu.
Even though the vaccine offers limited protection, it is not completely without effect. According to experts, the illness is less severe in vaccinated people and complications are more seldom.
To protect yourself and others: the vaccine protects the majority of vaccinated people from the flu and its consequences. It also prevents you from spreading the illness (unknowingly) to other people (including at-risk groups such as pregnant women and those with chronic illnesses).
To lower the risk of serious complications: there is less chance of secondary infections developing in the flu-weakened body. These infections are bacterial and can be more dangerous than the original illness. The vaccine prevents serious outcomes from developing in at-risk groups in particular.
No days spent in bed or hospital: genuine flu can last up to two weeks, and in some cases even longer. Complications like a lung infection may lead to a stay in hospital.
Less expensive and time-consuming than catching the flu: the flu vaccine prevents expensive hospital stays and absences due to illness. On national flu vaccination day at the beginning of November, GP surgeries and many chemists offer flu vaccines with no need to register beforehand. The vaccine costs 30 to 40 francs. Health insurance covers the cost for people who are particularly at risk, if they have reached their deductible. In the workplace, these costs are often paid by the employer.
Less fear of catching flu: if you are vaccinated, you don’t need to be so afraid of taking public transport, going to shopping centres or concerts, or attending family celebrations – you can just relax, even in crowded spaces.
Aside from getting the flu vaccination, there are some simple measures you can take on a daily basis to prevent the transmission of harmful viruses.
If you still do not wish to get vaccinated, you should at least take basic hygiene precautions such as washing your hands and sneezing into a handkerchief – and stay at home at the first sign of illness out of consideration to others.
