New vaccine recommendations have emerged
The committee has set an age limit.
The Canadian National Advisory Committee on Immunization (NACI) has provided recommendations for the Johnson & Johnson vaccine, the first shipment of which recently arrived in Canada.
The committee recommends vaccinating people 30 years of age and older, but with a caveat. If a person does not want to wait for another vaccine, or if the benefits of Johnson & Johnson outweigh the risks, people under 30 can be vaccinated.
The NACI recommendations are not mandatory; each Canadian province is free to decide whether or not to follow them.
Johnson & Johnson's product is a viral vector vaccine, requires a single dose, and can be transported at moderately low temperatures. Viral vector vaccines contain weakened or non-viable microorganisms that induce an immune response but cannot cause disease. AstraZeneca operates on the same principle.
Health officials say that mRNA-based vaccines (Pfizer and Moderna) are preferable. They encourage the body to synthesize antibodies but do not contain the virus itself.
