Same level of antibodies

The working group studied data from a clinical trial involving approximately 500 adults and comparing the two types of injection. “People receiving the vaccine intradermally received one-fifth (0.1ml) of the dose subcutaneously (0.5ml) but produced similar antibody levels as people who received the subcutaneous dose. higher dermal », explained the WEA. On the other hand, the risk of skin irritation is higher.

Designed by the Danish group Bavarian Nordic, the Imvanex vaccine was initially approved to fight against smallpox, declared eradicated worldwide since 1980. Studies later showed that this vaccine was also very effective against monkeypox, less virulent.

Due to the similarity of the two viruses, the European health authorities approved the extension of its use on July 22, specifying that the injection must be subcutaneous, therefore deeper. This decision triggered a rush towards this now only authorized vaccine against this disease.
