Johnson & Johnson is a single-shot vaccine, meaning a person is fully vaccinated after just one dose.
Denmark has said it will not use USA drugmaker Johnson & Johnson's single-shot Covid-19 vaccine in its vaccination campaign, citing concerns over serious side effects involving blood clots.
However, the New Jersey-based company also has a pharmaceutical line pharmaceutical arm - called Janssen Pharmaceutica- that started work on a COVID-19 vaccine as soon as the pandemic began. Administering a second dose is crucial to effectiveness of the other vaccines, and is also a challenge for Dr. Henry who has made a decision to delay second doses as long as possible in order to give as many people as possible a first dose of vaccine.
The NACI said the single-dose vaccine should be limited to people in that age group who don't want to wait for the Pfizer-BioNTech or Moderna vaccines. These all use the virus' genetic code to promote an antibody response, but enter the cells differently.
The advice is nearly identical to that issued for the Oxford-AstraZeneca vaccine last month and comes as both are suspected of causing a new and very rare blood clotting syndrome.
Health Canada has paused the distribution of the Johnson & Johnson coronavirus vaccine after discovering that it was manufactured at the same Maryland plant which screwed up the ingredients in some 15 million doses of the jab meant for the U.S. market, ruining them.
The World Health Organization and European medicines watchdog have both authorised the J&J vaccine. The US Food and Drug Administration (FDA) has since ordered the facility to stop making more J&J vaccines until it addresses the violations and manufacturing errors, which resulted in 15 millions of those doses being destroyed, the report said.
The JNJ vaccines expected to come into the country do not come from the Emergent facility, Health Canada had said in an earlier statement.
Those shots will only be released for distribution once Health Canada ensures they've met its "high standards for quality, safety and efficacy", the federal department said in a statement Friday evening. That means B.C., with around 13 per cent of the national population, is in line for around 40,000 doses from the first shipment.
