Pinterest users searching for vaccine-related information will be directed to results from “public health organisations”.
Last year, the social platform stopped showing results for vaccine searches to tackle the spread of misinformation.
Social media companies are facing increasing scrutiny over how they moderate content on their sites.
In recent months, other firms including Facebook have taken some steps to address vaccine misinformation.
Under the new policy, Pinterest said searches for “measles,” “vaccine safety” and other related health terms will return results from public health bodies including the World Health Organization (WHO), the Centres for Disease Control and the WHO-established Vaccine Safety Net.
“We’re taking this approach because we believe that showing vaccine misinformation alongside resources from public health experts isn’t responsible,” the firm said in a statement.
“As we continue to tackle health misinformation, we remove it and the accounts that spread it from our service,” Pinterest said.
The firm also said it won’t show ads, comments or recommendations on results pages for vaccine searches.
