COVID-19 vaccination during pregnancy—already known to protect women from hospitalization and severe complications—can also protect babies younger than 6 months, researchers reported today.In other COVID-19 research developments, a separate team that looked at COVID-19 hospitalizations in kids found that levels jumped dramatically during the Omicron variant surge, especially in kids younger than 4, a group not eligible yet for vaccination.Real-world evidence of baby benefitsThe study on the impact of COVID-19 vaccination during pregnancy on the youngest infants examined hospitalization trends across 20 children's hospitals in 17 states from July 2021 through January 2022.

The team published its findings today in an early online edition of Morbidity and Mortality Weekly Report (MMWR).At a Centers for Disease Control and Prevention (CDC) briefing today, Dana Meaney-Delman, MD, MPH, who wasn't involved in the study and heads the CDC's Infant Outcomes Monitoring Research and Prevention Branch, said scientists already now that SARS-CoV-2 antibodies are found in umbilical cord blood and can cross the placenta.

However, she said it wasn't known if the maternal antibodies provided any protection to babies."Now we have real-world evidence in babies younger than 6 months," she said.The study authors found that babies born to pregnant women who had received two doses of an mRNA vaccine were 61% less likely than those born to unvaccinated moms to be hospitalized with a COVID-19 infection.Of 176 babies hospitalized with COVID-19 over the study period, 84% were born to mothers who were unvaccinated during pregnancy.

Canada will scrap pre-arrival COVID-19 testing rule for vaccinated travellers April 1
COVID-19 testing requirement for fully vaccinated travellers, the federal government announced on Thursday.Starting April 1, vaccinated travellers won’t need to track down a COVID-19 test in the last day before their vacation ends.“Today’s announcement is encouraging, but let us remember that all measures are subject to review,” said Health Minister Jean-Yves Duclos, speaking to reporters Thursday morning.“We will continue to adjust them as the epidemiological situation here in Canada and abroad evolves.”Currently, all travellers entering Canada — regardless of vaccination status — have to show proof of a negative COVID-19 antigen test, taken within 24 hours of their flight or arrival at Canada’s border.As an alternative, they can show proof of a negative PCR test from within the previous 72 hours. Is Canada dropping its COVID-19 guard too quickly? Experts weigh in But starting next month, travellers who are fully vaccinated — with two doses of an approved COVID-19 vaccine — won’t have to show either.Fully vaccinated travellers might still have to undergo random testing when they arrive in Canada, but they don’t have to quarantine while awaiting their results, Duclos added.Unvaccinated and partially vaccinated travellers will be subject to a molecular test both when they arrive and again eight days later.
