Doha: Senior health officials at the Ministry of Public Health say multiple local and international scientific studies show clear evidence that for the majority of people the protective immunity against infection obtained from the first two doses of the vaccine gradually declines with the passage of time, supporting the need for a booster vaccination after six months following the second dose.
They also urged people to take the booster dose as the recent studies show booster doses to be highly effective at preventing severe infection from the new Omicron variant.
“Research supports MOPH's policy of offering the booster dose to all individuals who received their second vaccine dose more than six months ago,” tweeted the Ministry today.
According to the Ministry, “Studies showing up to 95 percent effectiveness against severe infection during the first six months, followed by a quick decline in immunity.”
