Vaccination Myths – What We Say
The VetTrust Medical Team Clarifies
Vaccination often causes uncertainty among pet owners. Is annual vaccination really necessary? Can vaccines harm my pet? And what about indoor cats – do they need protection at all?
In this article, we clear up common misconceptions and provide you with the information needed for informed decisions – factual, clear, and professionally backed.
“Do I really need to vaccinate every year?”
VetTrust adheres to the latest recommendations of the Swiss Association for Small Animal Medicine (SVK-ASMPA) as well as current guidelines and findings in small animal medicine.
Not every vaccine requires annual boosters – but regular vaccinations remain important. There are core vaccines (essential) and non-core vaccines (depending on lifestyle and risk factors).
Dog Vaccination Schedule
Some vaccines offer multi-year immunity, while others – like leptospirosis – require annual boosters.

Cat Vaccination Schedule
Your vet will create an individual vaccination plan tailored to your pet’s age, health, and lifestyle.

“Vaccines make animals sick.”
Fact: Vaccines in Switzerland are strictly controlled and considered very safe. Mild reactions like fatigue or slight swelling at the injection site can occur but are rare.
Serious reactions are extremely rare and generally far less risky than the diseases themselves. Our vets will openly discuss any risks and adjust the schedule if needed.
“Puppies are protected by mother’s milk – vaccination can wait.”
Puppies receive antibodies through mother’s milk, but this protection fades quickly – often before their immune system is fully developed.
This is why primary vaccination in early months is essential to bridge the gap.
“My cat stays indoors – does she need vaccines?”
Indoor cats can still be exposed to pathogens:
- Via humans (clothing, shoes)
- Parasites like fleas
- Other pets or accidental outdoor access
Many clinics also require up-to-date vaccinations for hospital stays. A reduced but targeted plan is often advisable – we’re happy to advise you.
“My pet is old or chronically ill – vaccination is too risky.”
Older or chronically ill pets often benefit most from strong vaccine protection.
We carefully balance benefits and risks, tailoring the vaccination plan to each case.
Our Conclusion: Vaccination Protects – Targeted and Individual
Vaccination isn’t about “everything every year”, but smart prevention based on real risks. We develop a plan that fits your pet and lifestyle.
