The corporate’s Covid-19 shot accommodates an precise model of the virus’ spike protein that can’t trigger illness however can set off the immune system. The vaccine developer mentioned it had began creating a spike protein particularly based mostly on the identified genetic sequence of the variant, B.1.1.529. “The preliminary work will take a number of weeks,” an organization spokesperson mentioned.
Novavax’s vaccine obtained its first emergency use approval earlier this month in Indonesia adopted by the Philippines.
The pharmaceutical big has additionally utilized for authorisation for his or her coronavirus vaccine within the EU with a choice potential “inside weeks”.

It additionally accommodates a substance to assist strengthen the immune responses to the vaccine.
“When an individual is given the vaccine, their immune system will establish the protein particles as international and produce pure defences — antibodies and T cells — in opposition to them,” the EMA mentioned.
If a vaccinated individual later got here into contact with the coronavirus, “the immune system will recognise the spike protein on the virus and be ready to assault it”. “The antibodies and immune cells can shield in opposition to Covid-19 by working collectively to kill the virus, forestall its entry into the physique’s cells and destroy contaminated cells,” the EMA mentioned.
The vaccination routine calls for 2 0.5 millilitre jabs, given intramuscularly 21 days aside, Novavax mentioned in a press release.
