Canada Stops AstraZeneca Vaccinations for Adults 55 and Younger

Canada’s National Advisory Committee on Immunization (NACI) has recommended that the Covid-19 vaccine should not be used in adults under 55 years of age at this time, while rare cases of serious blood clots were being further probed.

In a statement issued on Monday, the NACI said the cases, known as vaccine-induced prothrombotic immune thrombocytopenia (VIPIT), “have been recently reported in Europe following post-licensure use of the Covid-19 vaccine”.

“Cases identified so far have been primarily in women under the age of 55 years, although cases in men have also been reported and have mostly occurred between four and 16 days after receipt of vaccine.”

The statement further said: “Following population-based analyses of VIPIT assessing risk of Covid-19 disease by age, and considering that alternate products are available (i.e., mRNA vaccines), from what is known at this time, there is substantial uncertainty about the benefit of providing Covid-19 vaccine to adults under 55 years of age given that the potential risks associated with VIPIT, particularly at the lower estimated rates.

“As a precautionary measure, while Health carries out an updated benefit/risk analysis based on emerging data, NACI recommends that the vaccine not be offered to adults under the age of 55.

“Adults 55 years of age and older may still be offered the AstraZeneca vaccine with informed consent, given the increased risk of hospitalisation and death due to Covid-19 in this population and since VIPIT appears to be a rarer event in that age group.” Read Full Article >
