The Quebec government says fully vaccinated residents who have received the Oxford-AstraZeneca COVID-19 vaccine can receive a third dose of an mRNA vaccine before travelling, but recipients are on their own for weighing the risks of doing so. The extra shots are being offered because some countries don’t recognize the version of the vaccine made at the Serum Institute of India, and Canadians who have received it could find themselves barred from entry.

Robert Maranda, a spokesman for the Health Department, said a third dose of the Pfizer-BioNTech or Moderna vaccines doesn’t necessarily provide more protection compared with two doses, adding that the safety of receiving two shots of AstraZeneca mixed with an mRNA vaccine is unclear.

He adds that there are no studies that assess the impact of receiving three doses of two separate vaccines.

“The person should be properly counselled to be informed of the potential risks associated with this added dose compared to the benefits of the planned trip,” Maranda said in an email. “It is up to everyone to weigh the balance of risks and benefits.”

Meanwhile, Premier Francois Legault announced on Monday his government is relaxing more rules for bars, nightclubs, festivals, and entertainment venues.

Legault said on Twitter that beginning Sunday, bars and nightclubs can serve alcohol for an extra hour, until 1 a.m., and they must close by 2 a.m. Festivals will be able to host a maximum of 15,000 people outside – up from 5,000. Indoor venues will be permitted to welcome a maximum of 7,500 people seated indoors, up from 3,500. Dancing, however, remains prohibited.

Quebec’s public health institute says 83.5% of residents aged 12 and up have received at least one dose of COVID-19 vaccine and 62.55 are considered adequately vaccinated.
