A pulmonologist and the head of the respiratory research department at Blessing Health System, Humam Al-Farah said Sunday during his participation in Roya's Donya Ya Donya program, that the Moderna coronavirus vaccine is the most effective against the Delta variant, followed by the Pfizer-BioNTech jab and AstraZeneca.

He indicated that the antibodies formed following the administration of the Sinopharm vaccine resist the Delta strain less, noting that those who received this jab should take caution.

Farah pointed out that up until now, no directives were issued confirming whether or not individuals should receive a third dose of Pfizer, Moderna or AstraZeneca vaccines, but those who received Sinopharm can receive a Pfizer or Moderna 'booster shot' to supplement their immunity.

He emphasized that doses from different vaccines can be administered to one individual.

Farah denied that politics, America's control and its economic and media power have any role in promoting its vaccines, as the matter is purely scientific.

He stressed that the greater the spread of the virus, the greater the opportunity for new mutations to arise, indicating that the Delta variant is the most dangerous among all previous strains, as it is more prevalent, and affects younger people.

He said in the health center he works in, the ages of most cases of hospital admissions were in their 70s and over, but now, with the Delta variant actively being transmitted, a larger number of young people between the ages of 45-60 are regularly being admitted into the hospital, all whom do not suffer from chronic diseases.

However,  there have been no reported deaths from the Delta variant in his place of employment, with the exception of two, one of whom was a woman in her 90s.

He warned against countries declaring they have reached herd immunity, as no one is immune to the virus as long as another country is battling it.

Herd immunity is only obtained when 75-85 percent of the population is vaccinated, said Farah.
