Director of the Allergy Immunology and Cell Biology Unit at the University of Sri Jayawardenepura Dr. Chandima Jeewandara, says it is important to obtain the booster vaccine dose in order to protect one from contracting the Omicron variant of the coronavirus.
Dr. Jeewandara speaking at a media briefing today said a booster dose builds immunity fivefold in comparison to the first two vaccine doses.
Dr. Jeewandara said while the efficacy of vaccines in long-term illnesses is lesser, the current vaccine dose prevents serious illness.
He noted that hospitalisations of an individual with Omicron with one vaccine dose is 54 percent less, 64 percent in an individual with two vaccine doses between a period of two to 24 weeks, and 44 percent after a 25-week period since obtaining the vaccines.
Dr. Jeewandara said when the booster is obtained in six months, it leads to an 83 percent prevention against COVID-19.
Therefore, he noted that it is important to obtain the booster dose after three months to maintain immunity and build antibodies to fight the virus.
Dr. Jeewandara added many individuals claim that the virus is contracted despite obtaining all three vaccine doses.
However, he noted that the main objective of vaccines is the prevention of serious illness by COVID and to prevent deaths.
Dr. Jeewandara also stated that vaccines reduce the seriousness of symptoms, the duration of the illness, reduces hospitalisations, and the likelihood of spreading the virus to others.
