Giving booster vaccine Covid-19 has been carried out since mid-January as one of the protections against variants Omicron. In addition, experts reveal there are major benefits of booster vaccines. What’s that?
Pulmonary specialist Erlina Burhan revealed that the Covid-19 booster vaccination can trigger super immunity, which is a condition that helps a person become more immune to Covid-19.
“Boosters for individuals who have never been infected or who are naive can (form hybrid immunity). If people have no history (of being infected with Covid-19) coupled with this complete vaccination, super immunity will be formed,” Erlina said at an online event, Saturday (22nd). /1).
Super immunity or hybrid immunity is a condition of high immunity against all variants of the corona virus, including future variants. This condition is known to occur in individuals who have a history of being infected with Covid-19 and have received a full dose of vaccination.
Individuals with super immunity are said to be more immune than those who have never been infected with Covid-19 even though they have been vaccinated.
“But this theory should not be misunderstood, yes, with people who were immunized or vaccinated yesterday and then wanted themselves to be infected because they wanted to get hybrid immunity. No,” said Erlina.
According to him, there are alternative ways that can be used to achieve this super immunity or hybrid immunity. He said booster vaccinations, for example, could help trigger super immunity for the body.
“If you have received the primary dose twice, in order to achieve hybrid immunity, one alternative is to undergo a booster dose,” said Erlina.
In addition to the booster vaccine, Erlina also said that increasing the interval between doses also helps the formation of super immunity in individuals.
“Later boosting or lengthening the interval it promotes the efficient and persistent expansion of T cells (a class of cells that work during infection) of memory cells. so that, later boosting or extended dosing intervals in the naive population can increase the ability of memory T cells,” he explained.
However, Erlina said that the extension of the interval was only valid for a maximum of 10 weeks. He then reminded that the formation of hybrid immunity also needs to consider several things, such as the prevalence or number of Covid-19 cases in immunity.
“If the prevalence is higher, it is better that the interval is short, not long. If the immunity from natural infection is high, it may be possible to extend the interval from dosing,” he said.
“So don’t go blind if there’s a theory saying that extended dosing this vaccination interval will be better for hybrid immunity,” he said.
