Sweden has reported an 88% increase in primate testing over the past five years. The sharp rise contrasts with the previous five-year period.
Researchers used more macaque monkeys during COVID-19 vaccine development. These animals played crucial roles in creating effective vaccines against the virus.
Karin Loré, a vaccine researcher at Karolinska Institute, explained the temporary increase. She said macaques proved extremely important for developing COVID vaccines.
Loré does not expect primate testing to keep growing. She predicts numbers will return to previous levels soon.
Artificial intelligence could help reduce animal testing in future vaccine research. AI might identify potential side effects before human trials begin.
Sweden maintains strict animal welfare laws despite the testing increase. The country follows European Union regulations on animal research.
The ethical debate continues as science advances. Researchers balance medical progress against animal welfare concerns.
