COPENHAGEN (Reuters) - Getting a third dose of either Pfizer-BioNTech's or Moderna's COVID-19 vaccine offers a "significant increase" in protection against the Omicron variant in elderly people, according to a Danish study published on Wednesday.

The study, which is not yet peer-reviewed, investigated the effectiveness of COVID-19 vaccines that use so-called mRNA technology against the Delta variant and the new, more infectious Omicron variant.
