fifteen people with links to monkeypox cases have been given the smallpox vaccine, and around 10 others were booked to get the shot on tuesday, montreal’s public health department says.
quebec says it is administering the imvamune smallpox vaccine to “high-risk contacts” of confirmed or probable cases of monkeypox, a rare viral disease first detected in the province two weeks ago.
since monkeypox is closely related to the virus that causes smallpox, administering a smallpox vaccine can prevent people from contracting the disease or make it less severe, officials say.
because the vaccination campaign is targeted and based on contact tracing, it’s impossible to say how many people might get vaccinated, said marianne paquette, a spokesperson for montreal public health.
a single dose of the vaccine can be administered within four days of exposure. a second dose can follow only if the risk of exposure is still present 28 days later.
officials have said several montreal cases were linked to a traveller who came from boston.
paquette said the public health department does not have any more information about the possible source of the montreal outbreak. “at the moment, the priority is on limiting the outbreak rather than on finding the origin,” she said.
