Dr. Cathriona Walsh believes it's not possible to say for certain if an additional booster will be required to protect against further variants.
She says it depends on how long antibodies last for from the third booster.
Dr. Walsh believes a successful booster campaign in Ireland is the reason behind milder omicron symptoms.
Speaking on Let's Talk the Leitrim based doctor says time will tell whether or not a fourth dose will be required.
