Hong Kong family physician Natalie Hutchins has been inundated with calls since the city started rolling out its Covid-19 vaccination programme in February.

Reassuring patients about potential after-effects of the different jabs is part of Hutchins’ daily routine, as people struggle to process the overload of information – from proven side-effects to conspiracy theories – circulating online.

And she says most calls are from women. “There are a lot of scary stories circulating on the internet, about infertility, about the impact of vaccines on fetuses,” says Hutchins. “There is a lot of misinformation spreading about vaccines and women’s health, and that’s dangerous.”

“I try to reassure my patients by saying that we must focus on what the evidence shows,” Hutchins says. “And the evidence shows that these vaccines are really safe. But we understand it can be a tricky thing for people to get their heads around.”

The science is constantly evolving, adding to the many challenges faced by governments and medical experts worldwide. On April 7, the European Medicines Agency – the EU’s medicines regulator – announced that there is a “plausible link” between rare types of blood clotting and the AstraZeneca vaccine.
