BREAKING
Sheikh Qassem: Resistance is a source of power for Lebanon that must be preserved.
Sheikh Qassem: "Israel" must implement the agreement as Lebanon has already done so, and any new accord would amount to absolving it and opening the door to further attacks.
Sheikh Qassem: We do not wish to assume anyone's role; those accusing us of this must cease their accusations.
Sheikh Qassem: We will recover our lands through national solidarity; Resistance's goal is national liberation, while enemy goal is occupation.
Sheikh Qassem: Protection of sovereignty protects Lebanon. It is in real danger because of US belligerence, greedy Israeli expansion.
Qassem to Lebanese people: We are not asking for support but for us not to be stabbed in the back in the back or for some to serve Israeli interests; government is primary party responsible for [preservation of] sovereignty.
Sheikh Qassem: "Israel" can occupy, but it cannot persist in occupation of our land.
Sheikh Qassem: Intimidation will not change our stance of resistance and steadfastness. We are not advocates of surrender or defeat, and we will never accept it.
Sheikh Qassem: Where does US stand regarding enemy's unjustified assassination of a government worker and other civilian martyrs?
Sheikh Qassem: Is the Lebanese Army's defense of its land and citizens an accusation [leveled against it]? Where does US stand regarding the enemy's killing of civilians and constant destruction?

    WHO noted that the UK study's preliminary results should be interpreted with caution.

The World Health Organization (WHO) confirmed Friday that preliminary results of a UK non-peer-reviewed study showed that the Pfizer and AstraZeneca vaccines are less effective against the Omicron variant than they were against the Delta variant.

Referring to a preprint named "Effectiveness of COVID-19 vaccines against the Omicron (B.1.1.529) variant of concern," during its technical brief on Omicron, the WHO indicated "a significant reduction in vaccine effectiveness against symptomatic disease for Omicron compared to Delta after two vaccine doses of either Pfizer BioNTech-Comirnaty or AstraZeneca-Vaxzevria vaccines."

However, the WHO document read that a Pfizer booster showed higher effectiveness against Omicron two weeks after receiving the shot, which is was slightly lower or comparable against the Delta variant.

The organization noted that these preliminary results should be interpreted with caution.

In November, the WHO identified the new strain as one of concern, as its high number of mutations possibly allows it to proliferate 70 times faster than the original COVID-19 and Delta variants.
