Find your vaccine batch
A website now lets you see the possible side effects recorded according to the batch number of your COVID vaccine. This code can be found on the vaccination card you received when you were vaccinated against COVID, or in masanté.be.
Please note: some codes do not correspond to batches but are rather a multi-brand reference designating a vaccine. Note also that the same batch numbers can produce different effects.
The site lists batches in several categories: American batches and batches from all other countries, as well as batches by manufacturer (Pfizer, Moderna and Janssen).
