Vaccinated people who have recently been infected with COVID-19 should still receive a third injection, despite the natural immune response of the infection itself, according to the BC provincial health officer and an expert from the SFU .
“When you feel better and have recovered from this infection, you can get your booster dose and we encourage you to take your booster dose,” Dr Bonnie Henry said at a press conference Tuesday.
Ralph Pantophlet, associate professor in the faculty of health sciences at Simon Fraser University, said that just like people infected before vaccines were introduced were encouraged to get vaccinated, vaccinated people who are infected should receive a third injection after healing depending on the level of natural immunity following an infection varies from person to person.
“Even if you have been vaccinated and you have been infected with the Delta variant or the Omicron variant or any variant, you should consider, after some time after recovery, to get a boost,” he said. he declares.
“While it’s likely that the infection naturally boosted your immune response, this infection may not have boosted that immune response as well as a vaccine could.”
Pantophlet says vaccines do a better job of targeting the spike protein.
“If you get an infection your immune system makes antibodies or develops an immune response to everything the virus has to offer, to every protein, which is great,” he said.
“But it’s really the spike protein that is the key. So getting a vaccine will boost immunity or boost the immune response specifically at the spike.”
According to the Government of British Columbia’s Recalls website, all people 18 years of age and older will be asked to receive a third dose approximately six months after receiving their second injection.
Those who have had COVID-19 and are six months away from their second dose are encouraged to receive a booster after completing a period of self-isolation and at least 10 days have passed since the onset of symptoms or, for those without symptoms, the date of a positive test result.
