The National Advisory Committee on Immunization in Canada is currently evaluating various Covid-19 vaccine options and schedules and is expected to provide guidance in the coming months. Meanwhile, the U.S. Food and Drug Administration has already cleared updated Covid-19 shots from Moderna and Pfizer-BioNTech for individuals aged 6 months and older.
Pfizer and BioNTech have announced that their new vaccine can be administered as a single dose for individuals aged 5 and older, irrespective of their vaccination history. Children between 6 months and 4 years old will receive the vaccine as a three-dose series if they haven’t completed a primary Covid-19 vaccination course. For those who have completed the course, a single dose will be sufficient.
The companies anticipate that the updated vaccine will be available in Canada in the coming weeks. They are also closely monitoring emerging strains of the SARS-CoV-2 virus and conducting studies to assess the vaccine’s effectiveness against the Omicron BA.2.86 “Pirola” variant and the globally dominant EG.5.1 “Eris” subvariant.
